Sample Experiment

Materials

One of the following for each group:

  • Needle
  • Tweezers
  • Bowl
  • Water

Procedure

  • Fill the bowl with water. Using the tweezers, carefully pick up the needle and place it on top of the water. You may have to try it several times before you succeed. You will know you have done it correctly when the needle "floats" on top of the water.
  • Observe the needle carefully. How would you describe the way the needle sits on the water? Write down your observations in your folder. When it is time, share your thoughts with other students in your group.
