Students explore algal blooms.  In this ecosystem and health lesson, students define and describe harmful algal blooms, then discuss ways in which the impact of these algal blooms could be reduced.  Students work in groups to...

Students research coral reefs and identify their benefits to humans, threats to the reef, how to reduce and eliminate threats, and more. In this coral reef lesson plan, students research the reefs, and take a field trip to an aquarium.

Students create a garden.  For this ozone lesson, students discuss ozone injury, identify plants sensitive to ozone, and then plant their own ozone garden.

In this biology instructional activity, students write identify the different parts of a leaf shown in 5 different diagrams. They also complete 12 short answer questions after reading the information about leaves.

In this ecology worksheet students complete a crossword puzzle that incorporates all of the ecological vocabulary in the word puzzle.

Learners complete a food chain. In this ecosystem lesson, students learn about producers, consumers and decomposers. Learners identify herbivores, carnivores and omnivores and complete two worksheets.

Students become familiar with the products made from various plants.  In this plants lesson, students experiment with natural dyes from plants.  Students complete a list of things made from plants. Students answer...

Learners observe the similarities and differences between plant and animal cells. In this cell activity, students use microscopes to observe self prepared slides of animal and plant cells.

Students experiment with plants. In this plant lesson, students research the needs of plants. Students determine if all plants have the same requirements for growth.  In small groups, students experiment with different plants.

Students study life science. In this food webs and food chains comparison lesson, students examine the wetlands to discover the relationships that exist between the animals that live there. They participate in group activities and...

Students explore the differences between food webs and food chains.  In this wetland lesson students play a food web game and go on a scavenger hunt. 

Learners examine biodiversity and interrelatedness concepts.  In this ecology lesson plan students go on a field trip and fill out a data sheet. 

Young scholars discuss the importance of plankton in the ocean ecosystem. In this biology lesson plan, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect...

Students use TLC separations to identify various substances.  In this chlorophyll lesson students separate pigments found in different plants.

Learners conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson plan, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

Tenth graders create food web displays in the classroom. In this ecology instructional activity, 10th graders identify the different pollutants in the environment and their effect on organisms. They collect samples of sediments from the...

Have your class discuss food chains using this presentation. This resource goes through a step by step exploration of plants and the food chain. It talks about the energy of the sun, producers and consumers, herbivores and carnivores,...

It may not stand as a cohesive presentation, but individually you may find a use for these slides. One slide describes how civilization began once man learned to plant and harvest food. Another explores the population growth over time....

Using a jigsaw approach, earth science experts teach each other about the physical, biological, and geologic components of the carbon cycle, with a specific focus on the ocean.
