Seventh graders analyze and identify the role of the cell membrane and nucleus. They create flash cards to help them review cell structures. They also compare plant and animal cells.

In this cells worksheet, students click on the links to learn about the plant and animal cells complete a comparison chart and answer short answer questions about it. Students complete 10 questions total.

In this plant pigments worksheet, students compare the function of 3 types of pigments: chlorophylls, carotenoids, and phycobilins. This worksheet has 23 fill in the blank, 3 drawing, and 2 short answer questions.

Students make either and insect or a spider using materials their teacher provides. They then draw of picture of their organism and defend why it is either a spider or an insect.

Sixth graders explain what a negative feedback system is and they distinguish it from a positive feedback system. They describe examples of how negative feedback is used in both nature and technology. , Students define homeostasis, and...

First graders look for geometrical shapes in nature to help them appreciate the diversity of the natural environment.

Students distinguish the differences between Prokaryotic and Eukaryotic cells. Using microscopes, they examine a variety of plant and animal cells. Working in groups, they draw and label plant and animal cells and show the mathematical...

Students explore the cell and cell processes. They create "cytoplasm", make a model of the cell and its organelles, and simulate the osmosis and the diffusion of materials into and out of the cell.

Students observe their own epithelial cells from the inside linings of their cheeks using DigiScope technology. They prepare a slide with both onion cells and epithelial cells and make an illustrated booklet for a PowerPoint presentation...

Students explore biology by creating a poster with classmates. In this oceanography activity, students identify the importance of coral reefs to the ocean's ecology and examine a food web of ocean animals. Students define a list of...

Students create a dichotomous key using potato chips. In this classification lesson, students sort potato chips into groups based on observable characteristics. They record their results to create a dichotomous key in preparation for...

Learners view a video clip about animals and their habitats. They work together to discuss how different animals adapt to their environments. They create a new habitat for a specific animal and draw new adaptations for them.

First graders identify the parts of a seed. In this plant biology lesson, 1st graders are given a seed and identify each part of the seed by using a hand lens. Students plant a seed and graph the growth.

Students create their own terrariums.  In this ecological model activity, students create terrariums using soil, seeds, pebbles, and two liter bottles.  Students compare the elements of a  terrarium to a food web.

Students create a design for a school garden. In this garden design lesson, students analyze what plants grow best in their school's climate and work in teams to design a garden. Students measure the existing space, determine the...

Identify the properties of fats and lipids. Compare the properties of saturated and unsaturated fatty acids Identify foods containing triglycerides and identify which foods contain saturated and unsaturated fat Discuss the function of...

First graders ponder the question of how plants help their lives. They observe and compare properties of several different plants. Differentiate between living organisms and nonliving objects.

Third graders practice using classification techniques to identify local trees.  In this plant life instructional activity, 3rd graders discuss how trees differ from other plants and what characteristics are unique to trees alone....

Students participate in an adaptation scavenger hunt at. They obtain various plant specimens, and sort the plants based on whether they came from a desert, tropical rainforest, or wetlands.

Third graders view a clip of the video Backyard Safari, "Trees," and portray the life cycle of a tree. They also view a clip on structures of a tree and draw a diagram of a tree in their science journals.

Fourth graders study the characteristics of five coastal communities. They use logic cards and matching activities to identify the proper community for plant and animal species.

High schoolers visualize plant and animal cells, explain the parts of a cell and their functions and distinguish plant cells from animal cells. Working Students, in groups, must present a particular portion of a cell to the entire class.

Learners examine how to classify living things by effects, environment, and activity. They explore various websites, develop a list of facts they learn about classifications, and participate in a distance online learning session with the...

Students identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.
