Water Density and Salinity
Learners observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the density...
Curated OER
The Weight of Water
Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.

Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. For 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.
Curated OER
Floating
First graders discuss with the teacher if everything will float in water. They observe a marble and determine whether it will float making predictions as a class. After observing the results, they discover that liquids exert an upward...
