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.

Complete 5E Science Unit:

  1. Engage: Which object will sink or float?

  2. Explore: Salt Water Density Experiment + Scuba Diver Experiment

  3. Explain: Connect Experiments to Science Concepts

  4. Elaborate: Deepen Understanding with Discussion + Ocean Zones in a Bottle STEAM Art Activity

  5. Evaluate: Think Pair Share + Reflections

4-60 minute Lesson Sequence:
