TRANSCRIPT
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.
