Every child should know about the dangers of hazardous household materials. They draw a line between the types of material and the best precaution to stay safe when using that material. They can complete a secondary activity which has...

In this dry cleaning instructional activity, students read about the chemicals used to clean clothes and the alternative possibilities for dry cleaning use. Students answer three critical thinking questions about the dangers of the...

Exactly how environmentally friendly is your school? From the air fresheners in the bathrooms to the cleaning solvents used in the classrooms, young conservationists search the school grounds for sources of air pollution in...

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...

Students 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...

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 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.

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 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.

The vast majority of hydrocarbons humans use help fuel cars, homes, and provide energy. A comprehensive lesson teaches pupils all about hydrocarbons. From alkanes, alkenes, and alkynes to benzene, classes study the preparation of these...

Halogens comes from a Greek word which translates to make salt. Lesson 27 in the series of 36 teaches pupils about halogens. Pupils read, discuss, and answer questions in order to learn about haloalkanes and haloarenes. From defining...

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.

Learners 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. Learners 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! 

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

High schoolers 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.

Students test different water solutions for the presence of ions. In this water testing lesson plan, students test for iron, calcium, chloride and sulfate ions in solutions. They indicate positive tests based on their results and they...

Students produce esters in the laboratory by combining different carboxylic acids with different alcohol. In this esterification lesson plan, students experiment with 3 carboxylic acids and 3 alcohols to produce 3 esters with fruit like...

Learners determine the contact angle of water on different surfaces. In this physics lesson plan, students calculate their percent error using a mathematical formula. They explain the advantages of using non-wetting surface for certain...

Fourth graders learn about reduce, reuse, and recycle and identify household hazardous products. Students learn about less hazardous alternatives and complete an inventory of hazardous materials in a typical household.

Fourth graders discuss the concept of reduce, reuse and recycle. They identify products in their homes that are hazardous and discover alternatives to them. They examine the inventory of other classmates hazardous materials.
