Students heat and cool a box of particles to see why ice, water, and steam are all the same stuff — and discover that everything is made of tiny particles too small to see.
Students will be able to…
Ice, water, and steam look totally different — but they’re all the same thing. What makes one turn into another?
Project this and slide the temperature up and down. Students watch the particles rearrange and record how movement changes from solid to liquid to gas.
Tap any phase to open the teacher moves and student actions.
Ice, water, steam — how can they be the same stuff?
Students heat and cool a box of particles.
Name the states and connect heat to particle movement.
Where do we see these changes every day?
Three quick checks on states and changes.
Aligned to Next Generation Science Standards and Common Core literacy. State-standard crosswalks available on request.
Develop a model to describe that matter is made of particles too small to be seen.
Make observations and measurements to identify materials based on their properties.
Conduct an investigation to determine whether mixing two or more substances results in new substances.
Write informative/explanatory texts to examine a topic and convey ideas and information clearly.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Give groups identical ice cubes and let them design a fair test of where ice melts fastest (sun, shade, hand, water). A printable fair-test planner 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.
