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 transfers heat energy slower
Here is a picture of our original design:
The materials we used were… foil foam cup rubber band tape
Results! What was the temperature of your water to begin with? After 15 minutes? After 35 minutes? 55 start after 51
| Time | Temperature (in Fahrenheit) |
| 0 minutes | 51 |
| After 15 minutes | 53 |
| 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…
MORE TAPE AND FOIL
These changes will improve my insulator because… because it will stay cold
New results:
| Time | Temperature (in Fahrenheit) |
| 0 minutes | 40 |
| After 15 minutes | 43 |
| After 35 minutes | 44 |
