Heat-Flow Lab Predict conduction, convection, or radiation — and which way heat flows. 
Insulation Engineer Pick materials to keep the ice frozen the longest — the R-values decide it. 
Thermal-Equilibrium Mixer Mix two bodies — predict where the temperature settles (not just the average). 
Heating-Curve Lab Heat a substance steadily — find the flat plateau where it melts and boils. Thermal Expansion Lab Heat a bonded two-metal strip — predict which way it curls (thermostats, fire alarms). All activities
Heat labs
Heat-Flow Lab Read a real scene, predict whether the heat travels by conduction, convection, or radiation — and which way it flows — then watch the mechanism play out. Insulation Engineer Pick materials and thickness to keep the ice frozen — or the cocoa hot — the longest. Predict which build wins, then see the R-values that decide it. Thermal-Equilibrium Mixer Mix two bodies of different mass, material, and temperature — then predict the temperature they settle at. Discover why it is not just the average. Heating-Curve Lab Heat a substance at a steady rate and predict what the temperature does at each stage — find the flat plateau where melting and boiling happen. Thermal Expansion Lab Heat a bonded two-metal strip and predict which way it curls — first which metal expands more, then which side it bends toward. The physics behind a thermostat, a fire alarm, and a circuit breaker.
Practice & play
Mixed Practice A short round across the kits you have played — brought back to make it stick. HeatForge Sprint Race your OWN best on what you already know. Timer optional, no penalty for a miss. Trick Questions Brain-teasers with a twist — spot why the obvious answer is a trap. Teach the Cast Teach a heat idea to a cast member still learning it — teaching makes it stick. Heat Duel 2–4 players take turns on one device — same questions, highest first-try score wins. Heat Expedition A progression trail through every kit — clear each stop of real practice, then move on. Progress Your levels, streak, and how each skill area is coming along — saved on this device. Progress report For grown-ups — a private on-device snapshot mapped to the skill areas.

-
Touch Conduction (contact-bound molecular transfer) -
Drift Convection (fluid circulation carrying heat) -
Glow Radiation (electromagnetic energy across empty space) -
Shift Phase change / latent heat (state transition without temperature change) -
Hush Insulation / thermal equilibrium (slowing transfer, reaching balance) -
Amass Heat quantity vs temperature — how-hot is not how-much; a lukewarm lake holds more total heat than a scalding cup -
Billow Convection — warmth makes things spread out and rise; heat needs room to move -
Rasp Friction heating — rub two things together and warmth appears; motion turns into heat -
Smooth Conduction toward equilibrium — heat always spreads toward even, and never un-spreads on its own -
Steep Heat capacity — some things soak up heat slowly and hold it long; water is a heat sponge
