Activity #8 U Are So Dense!
Students watch as the teacher demonstrates: if a single liquid is placed in a U-shaped tube, the level of liquid on both sides are the same. When the mass is greater on one side than the other, liquid is pushed from one side to the...

A SALT WATER-Y WORLD
High schoolers observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.
Curated OER
Solutions
In this solutions learning exercise, students read about solutions, solutes, and solvents. Students compare solutions with mixtures that are not solutions. Then students complete 10 fill in the blank, 12 matching questions, and 10 terms...

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.

Ice Energy
Students observe the chemical reaction that occurs when salt is put on ice, and use the energy that is released to make ice cream.
Curated OER
Ice Energy
Students investigate how salt affects the state of ice. In this ice cream making lesson plan, students change the freezing temperature by adding salt and observing the results. Students use experimentation and comparison to see how...
