WATER CHEMISTRY
Students list reasons why water is important and investigate and graph the freezing points of different solutions.
Curated OER
Does Size Matter?
Students explore chemical solutions. In this chemistry lesson, students investigate the relationship between three related experiments about solutions. Students determine variables that affect the chemical concentration of each solution.

Lego Atoms and Molecules: Chemical Reactions
Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein) before,...
Cornell University
Polymers: Making Silly Putty
Putty is proof that learning can be fun! Share the wonderful world of polymers with your class through an experiment. Young scientists create their own silly putty, then examine its properties.
Curated OER
Inter-State Matters
Students explore the six phase transitions between gases, liquids and solids for a variety of elements. Each group of students focuses on a different element, investigating its physical properties during each of the six phase transitions.
Curated OER
ZIPPLY Delicious Ice Cream
Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.

Eyes on Dissolved Oxygen
Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect dissolved...
Curated OER
If My Configurations are Correct
Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.
Curated OER
Activity #3 Finding Mass
Students use graph paper to construct a graph and determine the slope of a straight line. They determine the weight (mass) of paper clips with a pan balance. Pupils weigh an unknown number of paper clips, and to interpret the graph to...
Curated OER
11 - The Heat Is On
Students observe physical change of melting by observing substance in original state, melting substance, allowing substance to return to original temperature, determining if substance retained its original properties, and recording results.
Curated OER
How Can You Tell One Clear Gas From Another?
Fifth graders perform experiments to determine the identity of an unknown gas sample. In this chemistry lesson, 5th graders fill balloons with air, oxygen, hydrogen, and carbon dioxide. They use mass and reactivity to identify the gases.

Radioactive Decay and Half-Life
Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....
Curated OER
Periodic Trends
Students identify the different periodic trends. For this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.
Curated OER
How Much Do I Know About Water?
Sixth graders explore how water behaves on a penny. In this states of matter instructional activity, 6th graders observe water as they add drops to a penny. This instructional activity helps students apply the adhesive properties of...
Curated OER
Physical Changes of Water
Students observe changes in water. In this lesson about water and its forms, students perform an experiment to determine how water changes. Students analyze what causes water to be solid, liquid, or gas. Students record their...
