For this activity, you will need your computer and assembled thermistor sensor, plus:
1. 5 cups
2. Hot tap water from the sink
3. Ice cubes
4. A thermometer
5. A piece of paper, and a pen or pencil to write with.
1. Prepare 5 water baths of different temperatures by adding a different number of ice cubes to hot water. For example:
a.Water bath #1: Hot Water Only
b. Water bath #2: Hot Water + 1 Ice Cube
c. Water bath #3: Hot Water + 2 Ice Cubes
d. Water bath #4: Hot Water + 3 Ice Cubes
e. Water bath #5: Hot Water + 4 Ice Cubes
Prepare water baths in cups and place them on top of an absorbent surface like a towel.
2. Create a spreadsheet (either digital or by hand) where you will record temperature (measured from the thermometer) and resistance across the thermistor:
