Students determine the physical and chemical factors that affect plant growth. In this biology lesson plan, students explain the role of hormones in plants. They investigate how competition with other plants affect their growth.

Learners research a variety of local and world ecosystems. Students will create a collage to represent the biotic and abiotic factors and interactions important to their given ecosystem.Learners will understand that an ecosystem is...

Seventh graders design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrot for the materials to be decomposed, and their experiments are carried out in plastic...

Learners investigate plants and the effects beetles have on the plants. In small groups, they collect plants and observe the beetles as they interact with the plants. They record the conditions including temperature, cloudiness, length...

Students investigate the growth of yeast in a sugar solution. They verify the pressure of carbon dioxide using bromothymol blue. Students are asked to describe the difference between the contents of the test tubes used and to explain...

Sixth graders examine the factors that influence the stability of ecosystems. They construct a miniature ecosystem in a jar that includes plants, small fish, and snails, record the population changes over a period of four weeks, and...

Students explore a hardwood forest. In this forest ecology lesson, students examine the diversity and animals and plants as they explore their habitats at Poricy Park Conservatory. Students determine how biodiversity and abiotic elements...

Students examine biodiversity and interrelatedness concepts.  For this ecology lesson students go on a field trip and fill out a data sheet. 

Students plot the Kaibab deer population from 1905 to 1939 and analyze the changes over time. In this populations lesson plan, students investigate the causes of changing populations of the Kaibab deer and they find the carrying capacity...

Students explore the ecosystem by conducting a ziploc bag experiment. In this recycling lesson, students identify decomposer organisms in our environment and how they speed up the recycling process. Students utilize a ziploc plastic bag,...

Pupils investigate temperate forest ecosystems. In this environmental lesson, students discover different forms of decomposition and its effect on the environment.

Learners compare the population of insects in different microclimates. In this biology lesson, students collect data using probes to tabulate temperature and soil data. They predict how certain parameters change as an area goes...
