Keep-A-Cube S.T.E.M. Challenge engineering design process
Don’t be a drip… • What makes ice melt? • HEAT makes ice melt! The air around the ice cube is warmer than the ice. So you need to keep the warm air away from the ice cube. • To do this you need INSULATION which is a material that slows heat energy from passing through it.
Here’s the challenge… • Can you keep an ice cube from completely melting in 30 minutes? • Use the materials to make a Keep-A-Cube Box that will keep an ice cube from melting. • Put a second ice cube on a plate. This is your “control” cube. Don’t make changes to this cube. • Wait 30 minutes • Compare the ice cube in your Keep-A-0Cube Box to the ice cube on the plate. Which ice cube is bigger? Why? • Think about what makes ice melt as you design you box. You can wrap up the ice cube, cover the box, or do anything else you can think of.
Here’s what you are working with… Materials Group member jobs Head Hands Heart Mouth • 2 ice cubes • Cardboard box • Wax paper • Masking tape • Newspaper • Aluminum foil • Rubber bands • Paper plate
Question that… • How can you change the container so the ice cube melts more slowly? • What happens if you use a smaller box? • What happens if you use different materials like foam packing peanuts or cotton balls? Why?
S.T.E.M. in my life… • How can we apply what we learned from this challenge to a career? • How can we apply what we learned from this challenge to real life? • How did we apply what we learned from other S.T.E.M. challenges to this challenge?
