Students, in groups, select two cleaning agents that they feel solves their cleaning problem.

Learners read and discuss decomposers and how they affect the environment. In this decomposers lesson plan, students also discuss how engineers use decomposers to help the environment.

Young mathematicians dive into the number line to discover decimals and how the numbers infinitely get smaller in between. They click the zoom button a few times and learn that the number line doesn't just stop at integers. Includes...

Learners experiment to determine the efficacy of various household cleaning products and soaps as antibacterial agents. They work in groups to complete this four part lesson series which includes identifying household bacteria,...

Here are some instructions for leading learners through a hands-on activity for investigating ultraviolet radiation. First, introduce them to light and refraction. Then introduce them to the electromagnetic spectrum. Finally, give...

Pupils investigate the effects of a variety of cleaning agents on the biotic and abiotic properties in the Great Lakes. They work with student from other schools to determine a workable solution that reduces the impact of cleaning agents...

Tenth graders demonstrate that natural selection is an agent of evolution. They quantitatively apply the Hardy-Weinberg Principle to an imaginary population of fish. They utilize math and graphing skills, collecting and analyzing data,...

Students review what they know about quick breads and bananas. In this art lesson, students discover two different recipes for Banana Muffins off of the computer. Students prepare a recipe for Bananas Muffins carefully and clean up their...

Students participate in an experiment in which they test the cleanliness of the lab tables. They practice using different materials and analyze their results. They answer comprehension questions to end the lesson.

Students discuss pollution and the steps in the hydrologic cycle. They follow a drop of water through a watershed simulation. They discover the components of a water cleaning system as well.

Students demonstrate safe ways to handle bacteria, prepare agar plates, and grow bacterial cultures. They identify different kinds of bacterial colonies, and devise a controlled experiment.

Students discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.

Students investigate surface tension, adhesion and cohesion. In this surface tension lesson plan, students complete 3 activities to better understand the concepts of surface tension, adhesion and cohesion. Students add drops of water to...

An engaging experiment allows scholars to understand why the recommendation is to wash for 20 seconds with soap and water — while making them aware of their own habits! 

Learners use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.

Students explore volcanoes, locate them on maps, record general information about volcanoes, and organize information on a fact sheet.
