Metals and Non-Metals
A table of the physical properties of metals and non-metals opens this high-school chemistry handout. Also covered are the chemical properties of metals and non-metals, reactivity, and fossil fuels. There are no specific questions to...
American Chemical Society
Changing State: Freezing
There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning.

What Are Cells?
What's in a cell, anyway? Kids read informational text on what makes up both animal and plant cells, including a page of vocabulary terms they will need to be familiar with (cytoplasm, ribosomes, vacuoles, etc.). Full-color images...

What's the Difference Between Concentration and Solubility?
High schoolers discuss the difference between concentration and solubility as well as examine the difference in a hands-on activity. Using water and table salt, they experiment with solubility. They create different concentrations using...

Freddy the Fish
Students complete an experiment. For this water pollution lesson, students brainstorm information about river habitats and water pollution. Students then read the story Freddy the Fish and complete an experiment where they use a...
Curated OER
Sea Water Freeze
Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Curated OER
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.
Curated OER
Properties of Fresh and Sea Water
Middle schoolers work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.

Is There Salt in a Glacier?
What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts.
Curated OER
Point- vs. Non-point Pollution
Students differentiate between point and non-point pollution and determine how the different types of pollution are harmful to aquatic ecosystems. They complete a series of tests on a sample of "polluted" water and a sample of "pure" water.
