Students illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.

Young scholars, in groups, combine given materials from an everyday kitchen until a chemical reaction occurs and record the reaction time.

Learners use the scientific method to complete to experiments that have visible reactions. In this visible reaction lesson, students participate in an experiment with melting ice and one with inflating a balloon. Learners record their...

Students create piston systems and explore the conversion of linear to rotary motion that propels a car. In this motion lesson, students build and test a model piston/crankshift system and discover why there is a maximum limit to how...

Learners create a model volcano in groups, and discuss what each part of the model represents as they go along.  In this volcano lesson, students come back together as a whole group and discuss what group did the best work,...

Students identify liquids as conductors. In this circuits lesson, students build a circuit, then use various liquids to complete the circuit, and determine which liquids successfully conduct electricity.

Fifth graders observe and identify the differences between chemical and physical changes. In small groups they mix different substances together in glass beakers, and identify which had a chemical change, supporting their statements...

Fifth graders observe and conduct a variety of experiments to differentiate between physical and chemical changes. They mix cabbage juice with different liquids and record their observations on a chart. Students write down their...

Sixth graders, in groups, observe the difference between physical and chemical changes and create a collage of pictures to show the difference.

Students explore pH levels of different substances. In this lesson about pH, students work together in three to four groups to test substances. moving between three different stations performing tests on the substances to determine...

Young scholars use the scientific method to determine physical and chemical properties of unknown substances. In this scientific method lesson plan, students discuss chemical and physical properties of substances as a class after a...

In this chemical reactions learning exercise, students are given fourteen chemical reactions that they must write using chemical formulas for the reactants and products. They balance each equation by placing the proper coefficients in...

Students examine the properties of solids, liquids, and gasses. In this states of matter lesson plan, the teacher guides students through a series of experiments to illustrate each state of matter and how matter changes from one state...

Students are introduced to gases. In this science lesson plan, students demonstrate that gases are a state of matter, generate a number of gases, discover some properties of gases, compare some of the properties of different gases, and...

Students investigate how geologic sequestration reduces carbon dioxide concentration in the atmosphere. In this earth science lesson, students simulate oil mining in the lab. They write down their observations and complete the lab report...

Students examine the different techniques that may be used to reduce carbon dioxide in the atmosphere.  In this ocean pollution lesson students divide into groups and complete a lab to see how the ocean holds carbon dioxide.

Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.

In this matter worksheet, students answer ten questions about matter including the phase of matter, mixtures and how they are different from compounds, the physical and chemical properties of matter and the difference between homogeneous...

Learners use plant materials as indicators of acids and bases. In 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....

Middle schoolers investigate gases and their properties by completing 4 activities. For this gases lesson plan, students perform activities to show that gases take up space, they diffuse, and that odors and vibrations pass through gases....

Students investigate the pH of solutions and they learn how to use different types of indicators. In this pH lesson plan, students test various solutions with pH paper and determine if they are acidic, basic or neutral. They also test...

Learners conduct studies of states of matter. In this science lesson plan, students observe the properties of matter and classify different substances as solids, liquids, and gases.

Student explore states of matter. In this science lesson plan, learners define matter, identify the states of matter, tell about the properties of each state of matter, and demonstrate an understanding of the difference between a...

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...
