We've all been there: It's hot out and you want to eat some ice cream, but at first it's too cold to hold and then the sun melts it before you can enjoy it. This ice cream STEM challenge solves both of those problems!
A fun version of this, if popsicles aren't your favorite snack, is a STEM challenge to save chocolate.
The STEM Popsicle Challenge
Challenge
Design and make a popsicle holder to protect your hands from the cold and also to slow down the rate at which popsicles melt.
Extra challenge
Make your popsicle holder reusable or recyclable so there is less waste.
You will need
Frozen popsicles
Recycled or handcrafted objects to make the ice pop holder. For example:
Bubble wrap
Aluminum foil for kitchen
Paper
Tape
Felt
Instructions for the STEM Ice Pop Challenge
Step 1
Design a stand for an ice cream/popsicle.
Think about functionality as well as appearance. For example, the popsicle holder should contain an insulating material to protect your hands from the cold and protect the popsicles from the heat of the sun.
Step 2
Make the popsicle holder. The design can be modified at this stage.
Step 3
Try the ice pop holder.
Does it protect your hands from the cold?
Does the rate at which ice cream melts slow down? To find out, you'll need to do a little research.
Leave it in the sun uncovered and with ice. Cover a second ice cream with the holder and leave it in the same place.
Check both popsicles every 5 minutes and monitor how quickly each one is melting.

Top tips for choosing materials
Bubble wrap is a great option as it will insulate the popsicles from the heat of the sun as the tiny air pockets trap the heat. Bubble wrap is a good insulator.
White reflects heat, so a white or light-colored material on the outside will help keep the popsicle cool. Black paper will absorb heat and speed up the rate at which the popsicle melts.
Extension Ideas
- Cover one popsicle with white paper and another with black paper to investigate reflecting and absorbing materials. Remember that you will need a control popsicle that is uncovered and all three in the same location.
- Organize an investigation to find out if leaving an ice pop in the shade slows the rate at which it melts.
- Design and build a pallet shelter to protect your pallets from the sun.
