Curated OER
Science: The States of Matter
Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Substitution and Elimination Reactions
In this substitution and elimination reactions worksheet, students complete 11 reactions by writing the structural formulas for the products. If no reaction occurs, they write N.R. They also write structures of the products for 3...
Beyond Benign
Breaking the Tension
The tension builds as learners experiment in your classroom. The 17th installment in a 24-part series has scholars investigate the concept of surface tension. After discovering characteristics of surface tension, they add a compound...

How Do I Get a Pure Sample of the Molecules I Make?
Students initially engage in online research and consult print materials to identify a compound to produce. Once a selection has been made, individually, students conduct lab experiments to isolate substances. The end product is a...

Spontaneity, Disorder and Entropy
In this physical and chemical change worksheet, students calculate the entropy change involved in different chemical changes. This worksheet has 4 problems to solve.
Curated OER
Acid/Base Indicators
Learners use plant materials as indicators of acids and bases. For this acid/base indicators lesson plan, students use boiled beets, cabbage, flowers, teas or berries that have been boiled with alcohol to test various acids and bases....
Curated OER
Ice Cream
Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.
Curated OER
Ice Cream
Students explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.
