# Grades 7,8,9 : LIFE SCIENCE - Activities 35 - 44

## 35. WHAT'S ON YOUR MIND?

SUBJECT: Science GRADE: 7,8,9 GROUP SIZE: Large in pairs TIME: 30 to 45 minutes TYPE OF ACTIVITY: Student Investigation TEACHING STRATEGY: Expository and Discovery CONCEPTS: ESP Telepathy "Fair" Experiments SKILLS: Identification and Control of Variables ' RESOURCES: BK - A.5;H 124

Objectives: To duplicate ESP experiments tried by some of the astronauts; to develop methods of experimental data collection and experimental control.

Materials: ESP cards from study sheet; data recording sheet for each student.

Teacher Background Information: An experiment which took place on one space flight dealt with ESP and Telepathy.

An astronaut tried to "send" thoughts to a person on the ground and visa versa. Quite a bit of scientific work is going on now in both the United States and Russia to test whether or not persons do have some ability to send information by thought wave alone. The following activity uses the same ESP cards the astronauts used in their experiment.

Procedure:

1. Run off the cards from the activity sheet on card stock or heavy paper if possible. You will need 5 each of the 5 designs.
2. Have students make a data sheet. (See illustration)
3. Have the students consider how to set up a "fair"

experiment. what variables need to be controlled? How should the data be recorded? How will a record of the actual cards turned be recorded? How should the data be evaluated? what is the probability of a correct response by chance? How many correct responses indicate 'ESP sensitivity?

1. Suggested format...Have two students take a set of twenty five cards out of sight of the other students.

Have one student turn the cards over one at a time and think of the card turned. Have the second student record on a response sheet what the card was and say "first card, second card," etc. until all twenty five have been turned. Have the students record the number of the card under the symbol on their sheet. (see the sample).

1. Have the students circle their correct responses as a student reads from the master list.
2. Repeat the experiment at least one more time and preferably twice.
3. Evaluate the data. If there are students who consistently get more than 9 or 10 correct responses try to test them separately. Some researchers say that about one in five persons has ESP powers. How does your class data stack up against this? '

Extensions: Research the findings of the astronauts. Try additional experiments in ESP including: A. Clairvoyance, B. Precognition, C. Psychokinesis.

## 38. AIRCRAFT AND THE ENVIRONMENT

Objectives: To help students understand how aircraft have impacted on the environment with positive results and with problems that need to be considered.

Materials: Books, pamphlets, encyclopedias on aircraft and what they do ("Aircraft and the Environment," Dept. of Transportation, FAA, Washington, D.C. 20591, is helpful); model rocket; %A engine; 2 ring stands; ring stand test tube clamp; ring stand upright; 2 clamps or wire; model rocket ignition system.

Teacher Background Information: Set up the ring stand "launcher" as follows: Attach the extra ringstand upright between the two stands with clamps (or wire the rod to the stands). Attach the test tube clamp to the rear ring stand. Insert the rocket engine in the clamp with the nozzle pointing away from the stand. BE SURE THE NOZZLE IS POINTED AWAY FROM FLAMMABLE MATERIAL AND AT LEAST 15 FEET FROM ANY WALL. If a vented hood is available, aim the rocket exhaust into the hood, If you do not do this experiment outdoors, ventilate the room right after the rocket is fired. Remember, the rocket discharges forward also. l* I Ea '51 .div . ', #A '

Procedure: Ask the students to observe very carefully all that happens during and after the rocket "launches." Set off the rocket and ask them to relate what happened. "It went forward," will surely be followed by "It was loud" and “It smells!" Focus on the pollutants it leaves: noise, smell, smoke, etc. Think through with the students what sorts of environmental ramifications there may be as we send shuttle crafts up every 10 days or so.

L-_c SUBJECT: Science GRADE: 7,8,9 GROUP SIZE: Large TIME: 45 minutes TYPE OF ACTIVITY: Teacher Demo Student Research TEACHING STRATEGY: Guided Discovery Open Discovery CONCEPTS: Environmental ~ Impact Pollution SKILLS: Observation Inference Research RESOURCES: BK - A.1;B FM - 6,34 129

If this little rocket can do what it does, have them imagine what 2 rocket boosters such as those on the Shuttle must be like. , Second, discuss some of the possible negative environmental results of any aircraft being launched today. (Noise? Emissions? Cementing over of acres of land? Crop dusting pollutants?) Third, have the students brainstorm and list the positive environmental impact of aircraft in the atmosphere. (Use in agriculture to seed, fertilize, apply herbicides and insecticides? in livestock production? forest management? logging? game management? freight hauling? people-moving?, etc.) Fourth, question the data as you go. what do the students know and understand about what the use of aircraft can do environmentally? Are there facts to support contentions that something is beneficial rather than harmful in the final analysis? Where can they look to find facts to support or refute what they think they know? Fifth, after the students have brought as much information to the discussion as they can, fill in any spots you feel are important and then ask the class to help you categorize the elements discussed into general areas of environmental concern and areas of environmental benefit. Have groups research information about the environmental impact of aircraft in the atmosphere and check if the original understandings were supported or not._ Provide time and materials for searching and have the students share their data with the whole class.

## sP1N oFFs FROM SPACE 1 3 I

Objective: to help students understand the "Spinoff" benefits of the space program for those of us on Earth. Materials: Various books and/or pamphlets on "spin offs" from the space program. (NASA Spin Off books have been available each year for several years and are super sources.) Procedure: 1. Ask your students to think of the things we now have because of the space program. Write the responses on the board and have someone keep a written record of them. (Most of the initial responses will quite likely be about the Space Shuttle, missiles or rockets, etc., and there will surely be a number of benefits the class will be unaware of. 2. When they have finished, explain that there are numerous benefits from the exploration of space and they can be broken into some basic categories: a. Communication Satellites b. Weather Satellites c. Landsat d. Oceanic Observers e. Defense f. Medical g. Other Technological Benefits (like freeze-dried food, alternative energy sources, computors, fabrics, metal processing, etc.) 3. Break the class into seven groups and have them research the benefits of space with a focus on their specific area of concern. 4. Have the students spend some time searching for information and collecting their data. Encourage students to write to NASA for information on the benefits of the space program. Michigan students can write to: Lewis Research Center, Teacher Information Center, Mail Stop 8-1, 21000 Brookpark Rd., Cleveland, OH 44135 or Aviation and Space Center, Oakland University, Rochester, MI' 48063. 5. After gathering their data, have the students compile the information in a booklet with illustrations of some of the benefits they have found. ha...

6. Bring the class together for a discussion and sharing of the booklets. Prior to class, write the original list of benefits the students had thought of on the board and then have each group present their booklet to the rest of the group. As benefits are presented, have someone write on the board those that were not brought up in the original discussion and compare the two lists. benefit ii-ill ?;%a,, l A 5  ‘%?f2 / - . .

## GETTING SPACEY AT THE AMUSEMENT PARK A 3 8

falling from a plane, just after a person crests a hill in a car, diving in a parabolic arc in a plane, are three examples. If no one mentions some of the rides at the amusement park, bring them up: the roller coaster, the free fall (Demon Drop or Texas Cyclone), the rotor, the parachute drop and the Enterprise or the wheelie. As you discuss some of these rides, talk about when the rider is falling down, falling up, is weightless or is pulling more g's than usual. A. Roller Coaster: what happens when you suddenly drop over the crest of a big roller coaster? What do you imagine your weight is at that point? what happens to the stomach in the valley of the roller coaster? Why? (Because you can go so fast, you can feel 3 g's and that's what astronauts pull at blast off of the Space Shuttlel) when you are back up again and have reached the second hilltop, what can you expect to feel at the peak? Do you know what this free fall curve is called? (parabola) what happens when you're in a roller coaster with loops? (You fall up, just like the water in the bucket.) If you had a ball tied to string that was tied to your writst, what would happen to it as you fell up? B. The Enterprise or Wheelie: This ride is almost a life-size version of the water bucket experiment- The bucket is now a padded car and the person gets to play the water. The rope attached to the bucket is replaced by a set of support beams that extend 25 feet from the center to the seat of each car. Ask the students to imagine the cars building up speed and tilting until riders orbit in a nearly vertical circle at a rate of 4 seconds per turn at a speed of 27 miles per hour. why is speed so important? what does the body pushing against the back of the car tell you about the g force? where would the force be greatest - at the top or at the bottom? Why? Explain to the students that before the Apollo moon missions, astronauts trained on a faster version of the super-gravity machine. It was called a centrifuge. Those tests of human reactions to g forces provided the data to guarantee that the wheelie is a safe ride. (Another “spin-off" from the Space Program!?!) Ask how the students might relate this ride to giant space stations orbiting the earth. How could the concept be

## PHYS ED IN SPACE 1 3 9

Objectives: To understand some of the problems the body faces while living in a weightless atmosphere; to apply the information in devising exercise equipment to offset the problems. Materials: ramificatons of living in space.l Books and pamphlets on the physical Procedures: 1. Talk with the students about what some of the problems of living in a weightless condition might be. Ask them to think about how their body functions in an atmosphere of 1 g. a. How hard is it to walk up hill? b. How much effort does it take to ride a bike? c. How are their muscles used to lift things? d. what sort of exercise do they get when they run? e. Are their legs, arms, lungs and heart all affected by exercise? f. How does gravity enter the picture here? g. what might happen to people who are unable to use their arms or legs for long periods of time, for example, when people have to stay in bed for sev- eral weeks? _ How vital is exercise to a well conditioned body? . How important is gravity and the resistance it provides to a well- conditioned body? h i 2. Discuss what might happen, then, if people were to try to live for long periods without gravity. Have the students make some predictions based on the earlier discussion. 3. Have the students do some research on what space scientists have found out about the body's response to weightlessness. Spend some time gathering information and sharing it in class. 4. Finally, have the students devise, either on paper or with a model, a compact, useful piece of exercise equipment that will help solve at least one of the physiological problems caused by weightlessness. Remind them to think about such things as: - atrophy of the muscles - loss of muscle mass, especially in the legs L» SUBJECT: Science GRADE: 7,8,9 GROUP SIZE: Large TIME: 60 minutes TYPE OF ACTIVITY: Discussion and Student Activity TEACHING STRATEGY: Guided Discovery Expository CONCEPTS: weightless Atrophy Conditioning SKILLS: Reading for Infor» mation Measuring RESOURCES: BK - A.1,5;C FM - 18,48,65,66 139

## DR. FREUD GOES T0 SPACE

Objective: To give students the opportunity to understand some of the psychological needs of living in an enclosed environment in space.


Materials: Paper and pencils. Procedures: 1. Have students break up into groups of six or seven. Try to see to it that the groups are as heterogeneous as possible. 2. Ask each group to spend ten minutes brainstorming the psychological needs of people living together 'hi a closed environment. Ask them to imagine that the vehicle is occupied by the six or seven people in their group, that the space they occupy is approximately the size of an average classroom and they are to be in this space for twelve days. Each group should have someone-jot down what the group comes up with. , 3. After they have spent 10 minutes brainstorming, inform them that the reentry ability of the capsule has malfunctioned and that ground control has determined that they cannot return for a year when they estimate 'the engineers will have a rescue vehicle built capable of picking them up and returning them to earth. All other areas of concern are taken care of: food is plentiful, all systems for pressurizing and decontamination, for example, are fine. Now, what other psychological considerations are there to be concerned with since the trip will take a whole year? Have them brainstorm and keep notes. 4. Bring the groups together and share what each of them came up with. How did the two periods of time affect their lists of psychological concerns? Can they prioritize some of the concerns? How important are the psychological ramifications to a successful living arrangement in a closed environment in space? 5. Finally, have the students work together in their groups to design a craft that is expected to be in space for two years. Assume all physical considerations have been met, but the groups are to imagine they are psychologists who are responsible for determining the most appropriate and emotionally healthy way to provide for the psychological ramifications of 40 SUBJECT: Science &» GRADE: 7,8,9 GROUP SIZE: Small TIME: 60 minutes TYPE OF ACTIVITY: Student Investiga tion TEACHING STRATEGY Open Discovery Guided Discovery CONCEPTS; Psychological needs Living in Space SKILLS: Hypothesizing Working in Groups Inference RESOURCES: BK - A.5;C;H FM - 65

living in space for two years. How would they provide for these in the design of the craft? Ask each group to share their craft and the ideas they come up with with the larger group. Drawings or models with explanations would be fun. 6. After the sharing, discuss whether there were differences in how each of the groups approached their task. were there any differences in what was deemed as psychologically important to the members of the various groups? Were there differences in what members within groups felt was important? Is it helpful to have a meaningful cross-section of people with a variety of perceptions when groups engage _in discussions of this sort? Have them check out how NASA approaches problem solving questions such as this. Extensions: Have students research the 1973-74 Sky Lab space station orbits for information on how a crew of three spent 84 days in space.

## IS ANYBODY OUT THERE?

Objectives: To demonstrate how to collect and grow living things in a nutrient medium; to relate the experiment to scientists searching for life in space. Materials: Refrigerator jars, plastic butter tubs or covered petri~ dishes; bread. Teacher Background Information: Molds, yeasts, or similar micro~organisms can be found almost anywhere in the world. Any bit of nmterial, whether of air, water, or earth, contains numerous examples of such micro-organisms. Under ideal conditions, they sprout into lush, spectacularly beautiful, microscopic jungles. This simple form of life offers space scientists a means of investigating the possibility of life on other planets. Scientists believe there. is a greater possibility that this type of plant life, or something comparable, would be associated with other living things. Accordingly, they have designed small robot instruments which land on the surface of distant planets and draw some of the surrounding material inside and drop it into a culture medium. Periodically, this liquid food is checked for chemical changes and the container for temperature or atmospheric composition changes. This information is transmitted back to the earth where the biological scientists compare it with already existing knowledge. Procedure: A covered refrigerator dish or clean glass jar makes a good environmental area for some types of microorganism growth. 1. Have students obtain a supply of molds by rubbing a piece of bread across a carpet or other floor area. Moisten the bread and put it into a covered evironmental area for several days. (Since molds and related plants do not possess chlorophyll, they should flourish without sunlight.) 2. After several days, have the students examine the growth with a low powered microscope or hand lens. Viewing is best with a bright light falling on the surface of the growth. Ask students to notice the rate and types of growth as well as changes in the base materials. 3. Ask students to think of experiments scientists 41 hm SUBJECT: Science GRADE: 7,8,9 GROUP SIZE: small TIME: Several Days TYPE OF ACTIVITY: Student Investiga tion TEACHING STRATEGY Guided Discovery Discussion CONCEPTS: Nutrient Medium Extraterrestrial life SKILLS: Experimentation Interpreting Data Hypothesizing RESOURCES: BK - A.3d;E FM - 36,39

might do in order to determine if life exists on another planet. Why would it be important to determine this? Might there be a need for protection from some microbes in space? Discuss virulent and benign forms of microorganisms. , 4. Ask the students what finding microorganisms in space might say about the liklihood of finding more complicated forms of life in space. Relate this experiment to the Voyager experiments and have the students do some research on how the scientists went about looking for life and what they found. Relate this activity to your general study of mycocetes. ‘§\(§‘ .LB 63- 4:\1\

## MOON ROOM FOR RENT - BEAUTIFUL VIEW

4. Explain to the students that this is a very integrated activity. They should know that they will be expected to use their skills in science, mathematics, architecture, sociology, psychology, political science and economics. They will be expected to consider health care, education and the question of who's in charge on this colony. It is expected that, though people can travel back and forth from the city to the earth (just as some raw materials and finished goods will) most of the people will live out their lives on the moon city and all contingincies for life must be accounted for. The teacher's ability to encourage students to focus on what they know and what they need to find out before and during the construciton is very important. It is very easy for students to fall into science fiction without reality based concepts and, though that can be fun, it does not help to meet the objectives of this lesson. Make certain the students know that evaluation will be based on what you have explained are your expectations about the project. In addition, they will be evaluated on how well they discuss their "city" and answer questions from the class about it. \ ‘VL/;i."<:i\ / 4"/ c_,»<;“j\>,\_ /' -> f § ff/ / /,_,~5_¢1./ ,~// af --\ Y _ __.- ._ - ,' \ ~ -1 . 3- ' '\\|,|| ,' I / 'fr I "’~ ,' "

## I SPACE COLONIES AND THE FUTURE

Objective: To utilize understanding of the hostile environment of space in constructing a model space colony. Materials: ANYTHING YOU CAN THINK OF! Styrofoam or paper plates, hamburger and pie containers; cardboard rolls; straws; styrofoam or paper cups; plastic soda bottles; flat cardboard, felt pens; string; toothpicks; glue; scissors; Exacto knives; masking tape; bits and pieces of colored paper; paint; styrofoam "peanuts" (they make great space peoplel). Procedure: (A) Brainstorming. 1. Write "The Year 2084" on the chalkboard and circle it. 2. Ask students to share what kinds of things they think we would have to concern ourselves with if we were living in space in the year 2084. Jobs, food, entertainment, oxygen, gravity, schooling, plants, storage, enclosed environment, etc. are some of the things that will likely come up. As they share, discuss the problems that are involved with each. Search for solutions. Share ideas with each other. 3. Ask the class whether they really feel we will be able to live for long periods in space in the year 2084. Sooner? Later? what will a space colony look like? what might we have a space colony for? These can be pretty important questions and the students should be encouraged to use all the information they have gathered through their aerospace and other activities to think about them. 4. Ask the class to make some predictions about the future and discuss the difficulty of making predictions in such swiftly changing times. Talk about how it is more vital than ever to learn how to think rather than learning how to memorize out of date answers. 5. Explain that groups of students will be constructing their own space colony starting the following day and they should be thinking about what they would like that colony to look like. Show them what you have gathered in the way of materials and encourage them to bring whatever else they think they will need. 43 SUBJECT: Science GRADE: 7,8,9 GROUP SIZE: Small TIME: Several periods TYPE OF ACTIVITY: Modeling Student Research Nilllllnn TEACHING STRATEGY: Open Discovery Guided Discovery CONCEPTS: Colonization of Space Human Needs SKILLS: Hypothesizing Futurizing Construction RESOURCES: BK - A.2c;B;C;H FM - 47,61,66 147

(B.) Construction. 1. Divide the class into groups of 4-5. 2. Explain that each group will construct a space colony where people live and work. 3. Explain that, at the end of the construction, the group will be responsible for explaining their construction, what the various parts of, the colony are for, how concerns such as weightlessness, lack of oxygen, decontamination, energy, entertainment, learning, sleeping, loneliness, etc., are being met on the colony. In addition, they should be able to talk about the people living in the colony, who they are and what they do there. 4. As the students construct their colonies, allow adequate time for research and discussion. They should know that real involvement during the construction will be the best way for them to truly understand some of the ramificatons of living in space. 5. As the students work, the teacher should also actively engage in the process: ask what is happening, what problems are being solved, what things are and encourage the groups to explore and answer questions they may not think of on their own. Reinforce the science concepts involved throughout the construction phase. (C.) Presentation. Ask each group to set up their display in an appropriate part of the room. The displays should be "self-explanatory" to some degree (much like a science fair project) but the groups will also be called on to make a verbal presentation. If possible, ask another class in to share the presentations. _E-,lg ;._.;~<:, __ _ * \<' Q 1§ii£!§£'"’i\ 4: * ;;' 2 _ f’ 1**WM®¥’. 'e%2»

## THE SHUTTLE GOES TO THE FAIR

Objectives: To give students a greater understanding of what happens as people live and work aboard the Shuttle; to provide ideas for possible science fair projects. Materials: “Space Shuttle Search Assignment Sheet," lfollowing activity); Books, pamphlets, etc. on the Space Shuttle; Shuttle models or pictures. Teacher Background Information: One of the concerns most science teachers have is getting students to do meaningful science projects either for class or for the annual science fair. One of the reasons for this seems to be that kids tend to do projects “in a vacuum;" they seldom see how what they've been studying relates to them or how it could be extended to an idea for a project. when they do understand how something can be bridged to their own lives, experiments or investigations become a great deal more inviting for most. This activity is an example of how this can work. Small groups of students research Shuttle topics and have the opportunity to present their information to the class verbally and with visual effects. Following the presentation, the teacher and the class engage in a brainstorming session on each of the eleven topics, looking for related ideas that might lend themselves to a question which could be investigated for a science (fair) project. Procedure: (Part I) 1. Show the students a model or pictures of the Space Shuttle. Ask what they already know about how the Shuttle works, what people do on it, how life is provided for. Because of press coverage, they should have some conceptual knowledge about the Shuttle; however, some of their information is likely to be incomplete and some may be incorrect. ENCOURAGE STUDENTS TO QUESTION RATHER THAN TO GIVE INFORMATION ABOUT CONCEPTS THAT ARE FUZZY. 2. when the discussion is completed, break the class into eleven groups and give each group ONE of the assignments from the sheet. Provide time and resources for the students to search for information on their topic. Explain they will be expected to compile their data and to present it on a specific day. 44 L...

3. At the scheduled time, have the students give their presentations to the class. Leave time for questions of the groups and, once finished, display the visual material in a Space Shuttle Centers Invite other classes in to see. (Part II) After the presentations, brainstorm each of the eleven topics with your students keeping in mind they are to think about related ideas that might possibly be worked up as a science project. They are to consider anything that relates to the particular Shuttle topic under discussion; they should not try to think of specific project questions yet ~ just related ideas, No evaluation or qualifying should be done about the ideas at this point, eithers Even if an idea doesn't exactly relate to the subject, it could still be an idea that leads to a good investigation question so write everything down, To give some idea of the sort of thing that can come up in sessions like this, here are a few ideas that came up for topics 1 and 10: 1. Sleeping on the Shuttle How much sleep do I really need? Do animals dream? How can the space in my bedroom be made more efficient? How long can people go without sleep? Does exercise help people to sleep? Are there ways to help people fall asleep? Can you sleep upside down? Standing up? 10. Manipulator Arm Devices to pick up stuff in my room Devices paraplegics use How does my arm/hand work? Robotics Artificial arms and legs Can you use the manipulator arm on Earth? The ideas that come from the brainstorming are just that - ideas - not project questions. The students and teacher will still have to formulate good research questions that can be turned into hypotheses which can then be investigated. .
