Students explore solids, liquids, and gasses and categorize and describe the three states of matter. In this chemistry lesson, students categorize items as solid, liquid, or gas based on the definitions given by the teacher. Students...

Volcanoes are among the most spectacular geological features on the planet. Jump into an exploration of these amazing phenomenon with this multimedia lesson series. Working collaboratively in small groups, young scientists view videos...

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

Learners explore chemical reactions. In this chemical reaction lesson, students conduct an experiment observing chemical reactions.

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.

Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...

Students investigate the acidity and alkalinity of common household products in an experiment. They use red cabbage juice and litmus paper to show the difference between strong acids and bases as they work with vinegar, dish washing...

Students perform a series of experiments on gas laws. In this chemistry lesson, students analyze the relationship between temperature, volume and pressure. They create a poster summarizing all the gas laws.

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

Students observe one of the direct effects of acid water on plant growth. Students engage in an experiment which will take about 2 weeks. Students will understand the effect that acid rain has on plant growth.

Students observe the pH change of an acid mixture poured over soil in a filter. Since the buffering capability of soils differs, you may want to do this experiment with several different soil types.

High schoolers perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.

Pupils conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...

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...

Sixth graders investigate earthquakes and volcanoes. They demonstrate fault lines with a folded piece of paper, conduct an erosion experiment, and construct a volcano using clay, baking soda and vinegar.

Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.

Students study the vocabulary of the states of matter. In this states of matter vocabulary lesson, students investigate and study the meaning of the words solid, liquid, and gas. They experience demonstration lessons that give them...

Students make a volcano out of a soda bottle, flower, salt, oil, and more. In this volcanoes lesson plan, students also read about volcanoes.

Second graders investigate chemical changes and reactions and will identify four characteristics that indicate a chemical change. In this chemical change lesson plan, 2nd graders perform experiments that promote chemical changes. They...

Fifth graders mix vinegar with different substances and explore the reaction. They record data from the experiment. Students examine chemical change, reaction, physical change and physical reaction.

Four lessons introduce elementary ecologists to salt marsh and sandy beach habitats. In the first lesson, they place shells and other materials in vinegar to determine if they contain calcium carbonate. In the second lesson, they read a...

Young scholars study the human digestion system and the functions of the stomach and small intestines.  In this digestion lesson students view a demonstration on the process. 

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.

Seventh graders trace the lava flow of an erupting volcano. In this earth science lesson, 7th graders experiment using baking soda and vinegar. They record and share their observations.
