Small Scale Sculpting: Etch Lab
Make works of art using a vintage yet effective etching strategy. The surface of a semiconductor chip has specific patterns formed through a process called etching. Through a lab investigation, young scholars recreate that process on a...

Chalk Fizz
Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....

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.

Using Environmental Models to Determine the Effect of Acid Rain on an Ecosystem
Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

Predicting Chemical Reactions
Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Dust in the Wind; Chemicals in the Water
High schoolers explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...

Great Glaciers!
Seventh graders study the earths surface and how changes happen to it. In this glacier lesson students complete a lab activity to see how glaciers form.
Curated OER
Boom and Fizz
Students investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.

Using Your Senses
Young scholars use their senses to make observations. In this senses lesson plan, students investigate unknown substances by using their senses for observations. Young scholars identify the number of the substances used, the color, the...

Mixtures
Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

Mystery of the Eleven Unknown Substances
Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.
