Station 1: Lava Lamp• Observe and record what

you see in the lava lamp.• How might density play

role in how the “goo” moves in the lamp?

• What does heat play on atoms and molecules?

• How might heat affect density?

Station 2: Mystery Ice

• Observe the two containers with clear liquid and ice.

• Why do you think the ice is floating in one liquid and sinks in the other?

• Can you come up with a possible explanation?

Station 3: Magic Eggs

•What differences do you observe between the eggs in the different glasses?

•What do you think causes the differences between the eggs in the glasses?

•Can you make a connection between what the egg is doing and something you have seen in the “real” world?

Station 4: Diffusion Confusion

• Place a few drops of food coloring in the container of hot water. Then place an equal amount of food coloring in the cold water.

• What do you observe?• Why do you think the two liquids behaved

differently?

Station 5: Bobbing Grape• What happens to a

grape with no skin in 7up?

• What patterns do you see the grapes taking?

• Does this remind you of anything you have seen or learned?

Station 6: Christmas Convection

• What happens to the windmill when the candles are lit?

• What is making the blades spin?

• Would the blades keep spinning if the candle were blown out?

BIG IDEA 1

As matter heats up, it rises.

When matter cools, it sinks.

BIG IDEA 2

The density of matter affects sinking and floating.

BIG IDEA 3

The amount of salt in water affects its density.

The more salt in the water, the more dense it is.

BIG IDEA 4

Particles that are heated have more energy, and therefore,

move faster than particles with less energy.

BIG IDEA 5

Changes in density can

cause convection.

BIG IDEA 6

Air is a fluid. By adding heat to air, you change its

density and cause it to rise.

BIG IDEA 7

Fluids will layer based on their densities. Two things that affect the density of a liquid are temperature and

salinity.
