Unit 1 · Energy & Matter in My World
Driving question: Where does energy go, and where does "stuff" come from? Across five lessons students build one connected model — that energy and matter are never created or destroyed, only transferred and rearranged — and then use it to design a real device.

The lessons
Week 1
Where does the warmth come from?
A hand-warmer heats up with no flame. Particles, energy, and exothermic change.
MS-PS1-1 · MS-PS3-3 Week 2Why does an ice pack get cold?
The mirror of Week 1 — energy absorbed (endothermic), still conserved.
MS-PS1-6 · MS-PS3-3 Week 3Where does a melting popsicle go?
States of matter as particle arrangement — and conservation of matter.
MS-PS1-4 Week 4When something burns or rusts, where does the matter go?
Physical vs. chemical change; atoms rearrange but are conserved.
MS-PS1-2 · MS-PS1-5 Week 5 · Performance taskDesign something that gives off or soaks up heat
Synthesis + the summative design task, scored with a 3-dimensional rubric.
