Solid
- Particle arrangement
- Packed tightly in fixed positions
- Shape and volume
- Fixed shape and fixed volume
- Motion
- Particles vibrate but do not travel around
- Examples
- book, brick, shoe
Week of Sep. 21–27
CURRENT SCIENCE · STATES OF MATTER
See what particles are doing.
Instead of memorizing isolated words, connect particle motion, heat, and every phase change.
⚛️Particle rule
Adding energy speeds particles up. Removing energy slows them down.
PARTICLE PICTURE
Four states, four arrangements
Choose a state and watch how its particles behave.
HEAT + PHASE CHANGES
Where is the energy going?
Tap a change to trace its starting state, ending state, and energy direction.
🧊Solid
Melting→Energy absorbs
💧Liquid
Real-life example: An ice cube becoming water. The substance takes in energy, so its particles move faster.
Boiling vs. evaporation
Both are vaporization. Boiling happens throughout a liquid; evaporation happens only at the surface.
TWO-WAY FLASHCARDS
Know the term and explain it
DEFINITION MATCH
Find the science word
Each miss gives a memory clue instead of just marking it wrong.
MATCH 1 OF 11
Anything that has mass and takes up space.
🧪
MATTER LAB
Run six mini experiments
Use particles, energy, and the gas laws to explain what happens.
