Your answer
11- Using a graduated cylinder, measure ice water (with no ice) and pour it into one small cup. Repeat for hot water (from the tap or from your teacher).
Your answer
12- Perform the control experiment (no insulation). Record your data in the “Control” column in the table below.
Your answer
13- Collect necessary materials and create a Mars Thermos for each cup and perform the experiment, noting the data in the data table below. Your goal is to limit the temperature change of the water to no more than 5°F in 10 minutes. Note the materials you are using for each cup here:
