Learners study about chromatography, a process used to separate mixtures. They see that chromatography is used to detect, separate or purify different substances. This nice instructional activity results in a beautiful t-shirt for each...

Learners work as a team to gather organisms from a stream to evaluate if the water quality is excellent, good, or fair to poor.

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.

Students explore how clouds are produced through three different age-appropriate hands-on experiments.

Seventh graders research on energy conversion. After they have researched several types of energy resources, teams of two to four create posters which depict how these resources can be conserved.

Students recognize that the sun is the source of energy driving atmosphere cells. They relate the motion of the atmospheric cells to mantle convection cells. Students recognize that the function of atmospheric cells is to move heat from...

Students study about chromatography, a process used to separate mixtures.

Students plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall. Next...

Engaging hands-on science lessons for grades 2-6 on chemical and physical changes.

This two-part lesson explores chemical change using Winogradsky Columns. Part 1 constructs student concepts concerning chemical and physical changes. Part 2 asks young scholars to compare physical versus chemical changes and observe...

In this chemistry lab, students will investigate, observe, and describe a variety of chemical and physical changes in matter. They will understand that this is part of everyday life.

Explains the difference between chemical and physical changes.

In this classroom lab, students will investigate the characteristics of a chemical change. Students will also provide a definition of what constitutes a physical change through observation of several examples. Students will use/create...

Identify chemical and physical changes and the differences between the two.

[Free Registration/Login Required] Explore how heat and temperature relate to phase changes.

Help solve the mystery and find the missing crystal. Following the activity, read more about chemical and physical changes, and then take a quick quiz to check for understanding.

Can you distinguish physical changes from chemical changes? After reading a brief summary of both types of changes, you'll be presented with some examples and asked to identify them.

Students will learn about reversible and irreversible changes in materials in this lesson.

Observe chemical and physical changes with this lab using everyday household items. Lab includes procedure and online data collection tool where answers can be saved and graded by teacher.

[Free Registration/Login may be required to access all resource tools.] Covers reversible and irreversible physical changes.

[Free Registration/Login may be required to access all resource tools.] Definition of physical change and examples, and how physical changes can be reversed.

[Free Registration/Login may be required to access all resource tools.] Definition of physical change and examples, and how physical changes can be reversed.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students identify the chemical properties of a substance and describe chemical changes and differentiate them from physical changes....
