Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

The Thermal Layers of Oceans
How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Lake Strata and Internal Waves
Use the classic density demonstration of placing a cola, a clear soda, and a diet soda into a tank of water. Then let learners attempt to pour some of the soda into layers in a clear container. The procedure explains a thermocline, and...

Why Do Some Things Float?
Students recognize that density determines whether objects sink or float. In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their results.

The Role of Density in Sinking or Floating: Relational Causality
Students consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids...

Ocean Layers
Young scholars investigate how temperature and salinity causes ocean layering. In this ecology lesson, students observe and sketch their experimental result. They report their findings in class.
Curated OER
Hot, Cold, Fresh and Salty
Students observe the effects of layering water and what is more or less saline than normal. For this geoscience lesson students create saline solutions, layer them and observe how the water becomes different temperatures in different...
