Students explore a variety of relevant lake water chemistry questions, compose responses, and present their results in a poster format. They, in pairs, answer questions about lake chemistry which are imbedded in this plan.

Students explore the topics of ocean water salinity, ocean life zones, marine life classification, and ocean food chains. They observe demonstrations, conduct experiments, complete quizzes and handouts, and analyze key vocabulary.

Students perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Students design, implement, and report a scientific research project using the scientific method. They explain the experiment and its findings through poster, essay , or other presentation method.

Young scholars consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem....

For this cell organelles worksheet, students read the structure and function of different plant and animal cell organelles to determine what organelle is being described. Students write in the 15 organelles into a chart.

Students understand the stages of a plants life. In this stages of plant development lesson, students read about bean plants and grow their own. Students record growth and photograph changes in their plants. Students label the parts of a...

Students build electrical circuits. In this instructional activity teaching pre-service teachers how to use the 5E instructional model, students use materials to explore how to create an electrical circuit.

Fifth graders investigate the food chain by viewing video clips. For this food web lesson, 5th graders investigate populations and ecosystems by viewing a video in class as well as visiting web sites. Students utilize the Internet to...

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...

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

In this plants worksheet, pupils watch movies about plant growth and then answer multiple choice and short answer questions about them. Students answer 6 questions total.

Learners study three structures of a plant as well as their locations and functions.  For this botany lesson students complete several activities on plant organs and their functions.

For this environmental worksheet, learners read the sheet that is about the greenhouse effect. They examine possible solutions to the problem.

Young scholars research an assigned biogeochemical cycle. In this cycle activity, students need to determine that all cycles need energy to continue. The young scholars will look at a given cycle to describe it, research and draw an...

Children explore the parts of a plant (flower, seeds, stem, leaves, and roots) using a dandelion as an example.

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.

Young scholars investigate how trees produce their own food. They examine chlorophyll cells with a microscope, analyze a cross section of a log, determine how old the tree was, simulate the distance of the roots, and create a play.

Students participate in a variety of experiments designed to illustrate types of heat transfer including conduction, convection and radiation. They complete worksheets as an assessment of the experiments.

Students collect information about various organisms in a forest ecosystem and create a mural that depicts organism interdependence. They then simulate a food web using a ball of string.

Students explore the food chain. They brainstorm and create a consumer-consumed food chains using magazine pictures and research materials. Students identify consumer-consumed relationships.

Students examine the effect of foreign species on various habitats. In groups, they identify the population dynamics of the zebra mussel. They calculate averages and graph data from Seneca Lake in New York. They develop hypothesis...
