Title: Building an Insulator
Categorize: Science
This week in science, we worked in teams to create a water bottle insulator that kept the water inside the bottle the coldest for the longest amount of time. First, we planned what we would need, how we would build it, and sketched our first design. Next, we tested our design to see how well our insulator worked. Below you will see the results and how we will improve our first insulator to make it even better!
An insulator is… something that slows the transfer of heat.
Here is a picture of our original design:
The materials we used were… tin foil, tape, rubber bands, water bottle, and a plastic cup
Results! What was the temperature of your water to begin with? After 15 minutes? After 35 minutes?
| Time | Temperature (in Fahrenheit) |
| 0 minutes | 55 |
| After 15 minutes | 51 |
| After 35 minutes | 55 |
The engineering process includes thinking about how to make your design better and re-building your product. The improvements that we will make to our insulator are… none
These changes will improve my insulator because… we are not doing improvements
Here is a picture of my re-designed insulator: no changes
New results:
| Time | Temperature (in Fahrenheit) |
| 0 minutes | 43 |
| After 15 minutes | 45 |
| After 35 minutes |
