Learners read about the bags that the Maya people made and about how reusing bags can help save our environment. In this environment lesson plan, students read and discuss conservation and observe pictures.

Students explore cycles in nature. In this cross curriculum agriculture lesson, students define "cycle" and research weather and planting folklore. Students make a bracelet in which individual colored beads represent the many "cycles" of...

Students explore paper making. In this cross curriculum multicultural ecology and art lesson, students follow written and oral instructions to make paper using common household items. Students predict the amount of paper use in their...

Learners explore the different types of renewable and nonrenewable energy sources. In this earth science lesson, students discuss the pros and cons of each type. They conduct a variety of experiments on renewable energy.

Students investigate the composting process through a variety of experiments. In this ecology lesson, students discuss the benefits of composting. They examine how compost affect plant growth.

Students conduct a series of experiments on mulching. For this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.

Students explore enzyme catalysis through a series of experiments. In this chemistry lesson, students determine the factors affecting catalysis. They explain the different uses of this process.

Though there are seventy-seven slides in this PowerPoint, only small bits of information are presented on each. It outlines the roles microorganisms play in the environment and spends time listing characteristics of each four different...

In this chemical reactions worksheet, students write rate expressions, determine the order of reactants and the rate law, and calculate the rate constant from data. Students calculate the half-life for given reactions. This worksheet has...

Learners explore how trash decomposes. In this ecosystem instructional activity, students discuss new vocabulary words, such as producers and consumers, and think critically to answer how landfills work.

Students explore what the soil temperature would be on the north and south sides of a building. In this temperature instructional activity, students hypothesize what the results will be using a thermometer and then after a week...

Students explore the environment by building a mock ecosystem. In this rainforest analysis lesson, students define many environmental and rainforest related vocabulary terms and discuss the current status of our planet's rainforests....

Fourth graders estimate various measurements. In this activity on measurement, 4th graders estimate the length and mass of multiple objects. Students discuss the difference between a guess and a reasonable estimate and discuss using...

Students examine how not all microorganisms are bad and that some can actually be beneficial.  In this yeast instructional activity students complete an experiment with yeast and answer questions.

Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.

Students develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Students create environments to demonstrate how earthworms interact with their surroundings.

Students perform various laboratory activities involving chemical reactions. They write balanced chemical equations for all reactions observed using computer software.

Students examine how easy it is to break rock. They investigate weathering and erosion in a number of activities.

Young scholars define and identify endothermic/exothermic reactions. Using a series of experiments, they construct and interpret potential energy diagrams for their reactions.

Students collect and study information about worms. They discover how an earthworm helps process and loosen the soil. They write in their journals as well.

Students perform an experiment to find out if plants grow best when grown in soil with no fertilizer, with chemical fertilizers, or with compost that they have made themselves. Students discover how agriculture practices can benefit the...
