Melt Proof Container Lab

That's Cold

Our task for this project was to make a melt proof container and record the temperature of the water every hour for four hours.

This is our container.

As insulators for our container, we used wax paper, cotton balls, plastic wrap, felt sheets, and tape. For a light reflector, we used aluminum foil.

This is the inside of our container.

On the inside of our container, we had a small cup with frozen water inside.

This is our finished container with the thermometer in it.

Temperature Recordings

Every hour for four hours we checked the temperature. These were our findings:

At 11:37 a.m., it was 9 degrees Celsius.

At 12:40 p.m., it was 8 degrees Celsius.

At 1:43 p.m., it was 7 degrees Celsius.

At 3:00 p.m., it was 5 degrees Celsius.


The total cost to make our container was only $1.70. The lowest in the class!

Felt Sheets (1) - $0.25

Tape (2) - $0.20

Wax Paper (1) - $0.15

Foil (2) - $0.50

Cotton Balls (4) - $0.20

Plastic Wrap (2) - $0.40

Job Analysis

1. Did the product meet the design specifications?

Yes. It was 20 centimeters or less on each side, it's cost was as low as possible, and the thermometer could be seen.

2. What was the total cost of the materials?


3. Did your team work well together?

Yes, we did, and we had fun doing it.

4. What was the quality of your team's work - okay, good, or great?

In my opinion, it was great. Sure, it could have been better, but I thought we did great based on the circumstances.

5. What was the biggest challenge for your team?

I think the biggest challenge was agreeing on how to make the container - we all had such great ideas!

6. What could have made the job easier?

The job definitely would've been easier is we could have used more materials.
