For unit 2, we measured mass,
Then rather than doing the density experiments listed in lesson 8, I substituted this one from Education Possible instead.
And we tested buoyancy.
In Unit 3, we determined whether or not a change is physical or chemical,
observed phase changes,
read lesson 12's experiment but didn't do it,
observed air pressure,
demonstrated the diffusion of scent molecules,
observed the effect of temperature on gas volume,
and demonstrated Charles's law.
