Upcoming chemists use chemical reactions to determine relative pH in two different acids. This is a terrific lesson plan for middle schoolers that can stand alone as a practice in precision and lab skills, or as part of the unit on...

Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

Students study the differences between an acid and a base.  In this pH activity students view a demonstration then test chemicals in groups.

Let's make coal flowers! With this fun activity, young learners watch and learn as they grow crystals! With simple household materials and the instructions included in this lesson plan, your class can grow their own crystals. Learners...

Who's going to get slimed? Your entire class! Scholars create slime using Borax, water, and white glue. Some food coloring can give the slime a bit of color.

Lesson 21 in a series of 36 specifically focuses on elements and their compounds from groups 13, 14, and 15 on the periodic table — including boron, carbon, aluminum, silicon, nitrogen, and phosphorus. Classes learn how some of these...

Ninth graders apply the skills of kitchen equipment and management.

In this marine animal worksheet, 3rd graders study the parts of seaweed. Students label 2 seaweed diagrams and study 24 household objects, circling those that come from seaweed extracts and/or ingredients.

Students use the net they make to dip macroinvertebrates at or below the surface. The flat side of the net allows pressure on the substrate so that organisms do not escape under the net. Two students hold onto the handles and submerge...

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Pupils describe environmental interrelationships using list of criteria. They are able to explain organism interaction, based on definitions provided. Also, students can use references and worksheets, to describe effects of pollution on...

Students consider the source of disease and parasites in West Africa. In this environmental issues lesson, students read "Working with Environmental Issues," by Fred Koehler. Students participate in an activity that requires students to...

Students observe crystals and their shapes and formation. In this crystal formation lesson, the teacher prepares crystal gardens for the students to observe, then the class finds examples of crystals in nature and observe a teacher...

Sixth graders use teacher prepared samples of substances. They perform the same observations and complete charts for each substance. After recording and analyzing their results, 6th graders make changes in the recipes to create a better...

Students engage in three short, hands-on, in-class demos which expand students' understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, they create paper snake mobiles to...

In this light worksheet, learners construct a pinhole viewer using a paper box, wax paper, tape and a pushpin. They answer six questions about their observations, the orientation of the images they saw, and the results of their experiment.

Students investigate the strength of solutions. In this scientific inquiry lesson plan, students examine various solutions of food color and water as they discover the concentration of the solutions by adding bleach to clear the color.

Fourth graders explore physical changes and the true life story of Wilson Bentley. They observe the changes that take place with snowflakes. Students discuss what happens when snow flakes melt. They create their own snowflakes using...

Eighth graders discuss uses and disposal of common household chemicals. They select a household chemical to test for impact on plant germination. Students decide how they want to set up a seed germination project. They design their plan,...

Learners investigate the by-products of wood and explore the wood products in their own environment. Products containing both cellulose and silvichemicals obtained from the trees are examined in this lesson.

Young scholars begin the lesson by completing a survey about how much and what types of water they drink on a daily basis. Using a worksheet, they calculate the amount of water an American uses each day and the amount their own family...

Young scholars read and analyze the story Away on the Bay as a springboard to discuss water pollution. They may look into ways in which water can be cleaned and a watershed restored.

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.
