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. Share in the comments: What method worked fastest in your house? Any surprises? Heatwave Hideout • Day 1 of 5
