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.
