Students will explore the concept of Thermal Regulation by conducting an experiment using a jar filled with ice and a temperature sensor to record data. Teachers will model the lesson by preparing the “control” jar.

Now, we are going to go back a step in the EDP to Understand. We’ve already worked on understanding existing solutions, understanding our client’s needs, and understanding our problem requirements. We are going to do an experiment to help us understand the science behind our problem, specifically how good different materials are at keeping something at a constant, stable temperature aka thermal regulation (which we have talked about before) and the scientific concept of thermal regulation: heat transfer.

Experiment Set-Up

Materials (per group):

• Plastic Jar
• Govee Sensor
• 1 insulator (student's choice)

Procedure:

• Step 1: Prepare your workstation with one jar and one insulator.
• Step 2: Attach the Govee Sensor to the inside of the jar lid using Velcro
• Step 3: Place 3 ice cubes in your jar (avoid broken ice cubes to ensure consistency). It should be ½ full and not touching the sensor.
• Step 4: Cover your group’s jar in your choice of insulator.
• Step 5: Allow time for the ice to melt. We will analyze the data tomorrow.

Teacher Note: Make sure that students use only one layer of one material for each jar.

We will export our data and visualize it in our next class.
