Teacher discretion
How do you test for hardness?
The scratch test
draw and label the full diagram of liquid, to solid to gas and back
Teacher check
What do these two changes have in common?
a dinosaur bone turning into rock over millions of years
salt and vinegar removing tarnish from a penny
Both involve chemical bonds breaking
Both are caused by heating
both are only physical changes
Both are changes of state
Both involve chemical bonds breaking
The behavior of particles in solids, liquids, and gases affects their properties and how they interact with their surroundings.
The diving board and the bottom of the girl's feet are both solids. Complete the sentence:
The particles in the girl's feet and in the diving board_____________. The particles in the diving board are too__________________ for the girl to pass through them.
- move quickly past one another.....close together
- move quickly past one another.......far apart
- shift and vibrate.....far apart
- shift and vibrate.......close together
