What do I need?
To complete these activities you will need:
 Pencil/pen and paper or a text editor
 Calculator
Overview
The Hooke's law interactive science activity consists of:
 An exploration of the simulation.
 A short multichoice question to help you determine which of the main activities you should try.
 The main activity where you will verify Hooke's law by determining the spring constant for Spring #1. It consists of:
 Calculating the weight of each mass
 Measuring displacements with a "virtual" ruler for several masses.
 Recording your results in a data table.
 Plotting your results.
 Calculating the slope of "best" fit line.
 Determining the spring constant for Spring #1 including the units.
 Checking the value of the spring constant with the theoretical value.
How long will it take?
These activities should take you between 30 and 45 minutes to complete. If you are far from completion after 40 minutes you should contact your teacher.
