"Oh, that's how gills work!"
Third Grade- Floating & Buoyancy
Blue Crabs Survive
The students observe, develop questions & investigate a blue crab's body to see how it survives.
Blue Crab Life Cycle
The students learn about the life cycle of a blue crab as they follow the life cycle of a blue crab in the Chesapeake Bay.
They use microscopes to observe the stages and learn about the salinity of the Chesapeake Bay waters.
Finding out about claws
"It grew one inch when it molted.
Second Grade- Blue Crabs Live & Survive!
Children use the scientific method to complete experiments.
Can soap float?Students use triple beam balances and rulers to measure mass and dimensions. They record their data in metric units. They make hypotheses about soaps.
Building a better boat: Students consider how the shape of the boat affects how much mass it can bear.
Carry out a simple experiment-one of the four:
*Do liquids float? Which ones?
*How much salt does it take to make a carrot slices float?
*Do heavy things always sink?
*Are balls that are the same size equally buoyant?
