Comic Panel 1
Today we will be looking at a fair test. Our investigation is based on the question "What is the best material to keep hot chocolate warm in the winter?"
  1. Students gather equipment.
  2. Predict which material will be the best insulator (stop the ice cube from melting).
  3. Wrap each cup with an ice cube inside with a different material.
  4. Using a thermometer wait till temperature of each cup gets to 0 degrees to begin stop watch.
  5. Using stop watch, set a timer for 3 mins and record temperature of cup. Repeat this step 4 times.
  6. Record results
