Play it cool by building your own ice box.
Materials

Materials Needed


  • cardboard box (less than one cubic foot)
  • waxed paper
  • masking tape
  • newspaper
  • aluminum foil
  • rubber bands
  • ice cubes

Instructions

Instructions


  1. Using these materials, make a container to see how long you can keep an ice cube from melting. Find out what works best to keep the heat away from the ice cube. Wrapping the box in aluminum foil? Hanging the cube?
  2. Put your ice cube in the container. Take another ice cube and don't put it in a Keep-a-Cube container. It will be your control. In 90 minutes, check both ice cubes. If at the end of 90 minutes, the control ice cube is the same size as the ice cube in your Keep-a-Cube container, the container didn't do much to keep the ice cube from melting.


Keep experimenting with ice cubes. Build another Keep-a-Cube container using different materials, like a plastic bowl instead of a box, or notebook paper instead of waxed paper. Test it out, then share your results with the world in our fabulous ZOOMsci feedback area.

We covered our box on the out side with foil and the inside with bubble wrap. Then we put our ice cube in and covered it with packing peanuts. It didn't melt at all!

Bailey, age 11 of Omaha, NE wrote:
The first time we tried our cube melted. The second time we tried, we put bubble rap on the bottom & sides, and put cotton balls all over the ice cube. It only melted a tiny bit.

The second time we did it we put packing peanuts in it and that made the that insulated very well.

Brock, age 10 of Omaha, NE wrote:
The first time, when we used bubble wrap, a plastic bag, and wax paper, it barely melted at all. Compared to the control cube, it did really well. The scond time we did it, we got rid of the plastic bag, and replaced the wax paper with cotton balls. I thought it would do worse, but I was wrong. It didn't melt at all.

Michael, age 10 of Omaha wrote:
The first time I did it it melted more the second time I did it I changed some things and it didnt melt much.

Frankie, age 11 wrote:
First it mealted in the 30 minute time period. The 2nd time it stayed. All that we changed was we didnt tape shutt and we ddidnt putt it in a bag. The 2nd time it mealted only one drop. So we found ouut how to keep a cube.

Josh, age 12 of Omaha, NE wrote:
We used a shoe box with bubble wrap inside of it and we put cotton balls and packing peanuts around the ice cube and our experiment was the most succesful.

Allyson of Yarmouth County, NS wrote:
I used different materials. I used a regular sized shoe box and used a larger sized icecube. Then I rapped the inside with tissue paper and left the outside bare. Where the sun was hitting the box, I put a towel to keep the sun from getting to close.

We added some of our own materials like a baby diaper, bowls, bubble wrap, and plastic wrap. We put a diaper in a cereal box and it lasted from 6:30 to longer than 11:00pm. We had fun doing this!
