This lesson is intended to address the BC Grade 5 Physical Science Learning Outcomes but may be adapted to suit a wide range of grade levels from Primary to Intermediate.
The teacher will guide students to discover that a wedge, can make raising or splitting an object apart easier. Discussion about wedges will follow the discovery lesson.
Station One: Fashion Design 101
- class set of large sewing needles with thread
- variety of buttons, bells that can be sewn on, sequins, beads,etc.
- lightly used sweater (cardigan type)
Station Two: Picasso Paintings
- paint brushes
- paint trays or containers with paint
Station Three: My Initials
- 6 small craft hammers
- 200 1" nails ( 10 nails per student)
- scrap boards donated by local carpenter (need a small board for each student to hammer nails into)
Station Four: Calendar Capers
- 6 pairs of scissors
- 3X3 squares of coloured tag; 2 per student minimum
- tagboard tracers of shapes under 3" such as apples, frogs, or butterflies
- At Station One the task is for each student to sew decorative pieces such as buttons, bells, sequins,etc (using a needle and thread) on the sweater.
- At Station Two the task is to paint like Picasso - piant a picture.
- At Station Three the task is to hammer nails into a board to form your first initial.
- At Station Four the task is to trace, then cut out shapes on tagboard to be used for the classroom calendar.
- Set up 4 stations with appropriate materials.
- Explain stations to students.
- Divide class into four groups, with one group starting at each station
- Each group will have a turn at each station, approximately 5 to 7 minutes.
- As students rotate through ask them to think about the tools they are using for each activity.
- A wedge is used for splitting something apart, peircing things or to raise up very heavy objects.
- Three of the four stations had tools that were wedges. Which stations were they and which tools were they?
- Is a shovel a wedge? Is a ladder a wedge? Can you think of other examples of wedges?
If you take two of the simple machine I am thinking of and place them together they form a wedge. What am I thinking of?
