It’s hot out there. Time to bring the cold inside.
Grab some ice cubes and a tray. Your mission: figure out how to melt your ice cube as fast as possible without using the oven, microwave, or hot water from the tap.
That’s it. Go.
Gather Your Gear:
• Ice cubes (at least one per person)
• A tray, plate, or bowl to catch the melt
• Timer (optional)
• Paper and pencil to record observations (optional)
Steps:
1. Everyone gets one ice cube.
2. Each person picks a strategy — hands, breath, sunlight through a window, a dark cloth, salt, sugar, pressing it between objects…
3. Set a timer for 5 minutes.
4. Compare results. What worked? What surprised you?
5. Try again with a new hypothesis.
Variations by Age
Age variations:
🐣 Ages 3–6: Just play with the ice — touch it, watch it, talk about what’s happening. “Is it getting smaller? Why?” No strategy needed. The wonder IS the activity.
🔍 Ages 7–12: Add a prediction round before you start. Write down what you think will work best and why. After, compare your prediction to what actually happened.
🧠 Teens: Challenge them to design the slowest melt insulate an ice cube using only materials in the house and see whose lasts longest. Bonus: look up why salt melts ice and whether that matches what they observed.
