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…

An insulator is energy that slows heat transfers 

Here is a picture of our original design:

The materials we used were…

We used a water bottle, tin foil, wire, hot glue, fabric, and pipe cleaner

Results! What was the temperature of your water to begin with? After 15 minutes? After 35 minutes?

Started temperature: 50 degrees F, Temperature after 15 minutes  54 degrees F after 35 minutes 62 deegrees F

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…

We will take off the handle and plastic wrap and add more tinfoil and cover it in 

These changes will improve my insulator because…

The polyurethane is a good insulator.
