Description
5E Ocean Science Unit: Salinity, Buoyancy, and Density!
With 40 pages of teacher slides, step-by-step guide with photos and videos, and editable student handouts - this is everything you need for a complete 5E science unit covering key tops of ocean layers, buoyancy, salinity, and density!
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.

NGSS5-PS1-3
Make observations and measurements to identify materials based on their properties. Examples of materials to be identified could include baking soda and other powders, metals, minerals, and liquids. Examples of properties could include color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility; density is not intended as an identifiable property. Assessment does not include density or distinguishing mass and weight.
NGSS5-ESS1-1
Support an argument that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from Earth. Assessment is limited to relative distances, not sizes, of stars. Assessment does not include other factors that affect apparent brightness (such as stellar masses, age, stage).
NGSS2-PS1-1
Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. Observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.
NGSS2-ESS2-3
Obtain information to identify where water is found on Earth and that it can be solid or liquid.
