Students explore the states of matter through the behavior of particles — and how adding or removing energy drives phase changes like melting, boiling, and condensation, moving matter between solid, liquid, and gas.
Students will be able to…
The same water can be ice, liquid, or steam — same particles, wildly different behavior. What changes, and what drives the transformation?
Project this and tap each state and phase change. Have students connect particle behavior to what they observe.
Tap any phase to open the teacher moves and student actions.
Same water, three forms — what actually changes?
Students investigate.
Teacher explains.
Apply.
Three quick checks.
Aligned to the Next Generation Science Standards (High School Chemistry) and Common Core literacy in science.
Develop a model to illustrate the energy change during a phase change or reaction.
Develop models to illustrate energy at the macroscopic and molecular scale.
Gather evidence about how particle structure affects properties.
Translate information into a visual model.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students read a heating curve and explain why temperature stays constant during a phase change even as heat is added. A printable phase-change sheet is in the Science library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
A quick self-check with instant feedback, drawn from this lesson’s key terms.
A print-and-go review sheet with a built-in answer key. Tap “Show answer key” to reveal answers, or print the clean version for students.
