Key Learning Outcomes
Learn about the STEM Career of an Oceanographer and Jacques Cousteau
Apply prior knowledge of how items sink or float based on everyday life experiences.
Predicate if an item will sink or float and justify reasoning.
Test to see if predictions are accurate.
Record predictions and results in a scientific process.
Predict how changing the type of water will change sink or float results. Compare and contrast saltwater to freshwater.
Light objects have buoyancy and float in water.
Divers have to add weight belts to their bodies to overcome the buoyancy of their bodies in the water.
Learn about the 5 oceans, buoyancy, salinity, and density.
Learn that oceans are salty and salinity and density increase buoyancy.
Learn the vocabulary of buoyancy, density, and salinity.
