What a Hard Test!
Fifth graders complete an exercise that introduces them to Moh's scale of mineral hardness. The scale is presented on the worksheet, and learners answer three questions which have them assign a hardness rating based on some clues. For...
Cornell University
What Is Rust?
Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.
Cornell University
Sound Off!
Time to witness the effects of sound. Learners analyze different materials to determine their abilities to absorb sound waves. They use free software to monitor the amplitude of the waves to verify results.

Sea Water Mixing and Sinking
Learners investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.
Curated OER
Sea Water Freeze
Middle schoolers 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

The Chemical Context of Life
An educational presentation includes atoms, molecules, the four major elements, as well as neutrons and protons. Additionally, slides focus on atomic number, mass number, atomic weight, polar and nonpolar covalent bonding, ionic bonds,...
Cornell University
Chemical Reactions
Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.
Discovery Education
School of Rock
Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...
