This test covers the following topics:
Solids, liquids, gases
Particle diagrams
Changes of state
Properties of solids, liquids and gases
Brownian motion
Melting and boiling points
Heating and cooling curves

Collision theory / kinetic theory crossword Do Now
Students are required to 'fill in the gaps' to complete the crossword. The purpose is to check their understanding about the collision theory and how scientists can increase rates of reaction.

The 7 solutions are:
activation, collide, energy, kinetic, orientation, speed, temperature
Year 7 or 8 Do Now on elements, compounds and the periodic table.
Students have to identify metals and non-metals using the periodic table, then have to determine the number of atoms in compounds, eg. 2 x hydrogen and 1 x oxygen in water.
