Crawl into the world of the darkling beetle with this scientific investigation. Watch as the insects move through the larval, pupal, and adult stages of life, recording observations along the way. Discuss the necessities of life as young...

When it comes to the carbon cycle, the sky really is the limit. The lesson begins with observing a closed ecosystem in a bottle. Then, scholars discuss and answer questions on the carbon dioxide and oxygen cycles. 

Student learns about the life cycle of plants by watching a time-lapse video. This activity provides students with further evidence that all living things grow and change as they progress through their life cycle.

Students examine the carbon dioxide cycle in the atmosphere. In this element lesson plan, students discuss the relationship between carbon dioxide on Earth and the plants that store it. Students play a game to ensure their...

Students create terrariums in containers in order to study the Water Cycle. They examine how the terrarium maintains life in the closed environment.

Students build a model to simulate parts of the water cycle. They recognize and explain the essential elements of the water cycle.

Learners illustrate the life cycle of a butterfly. In this life cycle lesson, students use the book From Caterpillar to Butterfly and the Internet to learn about life cycles. Learners use different types of pasta to represent the...

Students examine the relationship between chlorophyll and carbon dioxide in the atmosphere.  In this investigative lesson students study the local effects of climate change. 

Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.

Looking for a tree-rific addition to your water cycle unit? Teams of young foresters examine the role of transpiration in the water cycle through a week's worth of activities. Pupils analyze how trees take in and transport water during...

In this food chain worksheet, students review terms associated with food chains and food webs. Students also recall the water cycle.

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

Two very hip teenagers walk through the forest collecting evergreen cones. One teaches the other about gymnosperms: cycads, ginkoes, gnetophytes, and conifers. He tries to convince his friend how amazing cones are, while she defends...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...

In this Life Science worksheet, 8th graders match the vocabulary with the list while being tested on terms related to plant reproduction.

Scientists found fossils of plants more than 420 million years old—but plants existed for up to 100 million years prior to these fossils. Learn about the importance of plants to the entire planet. Viewing a presentation helps scholars...

The balance of nature can be a wondrous thing! With the 19th lesson of the 21-part series on systems, learners explore the cycle of photosynthesis and cellular respiration using a lab-based activity. Groups set up different test tubes...

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

Students study the role of plants in recycling water by collecting water vapor that is emitted, or transpired, by green plant leaves. They collect and measure the water that transpires through the tiny pores of plant leaves. Afterwards,...

Students examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...

Students are introducced to how respiration and photosysnthesis cycle carbon through ecosystems. They read background information that describes the role of the Sun as Earth's ultimate energy source and explains how the energy...

Students create a desert biome and a prairie biome and see how plants survive in both. In this biomes lesson plan, studnets create their biomes and see how the water cycle effect each biome and plant differently. 

In this carbon cycle lesson, middle schoolers review the carbon cycle and visit stations in the room where they experience every phase in the carbon cycle. Young scholars journal about their journey through the cycle and brainstorm...

Learners construct their own diagrams outlining the pathway of carbon and oxygen in our atmosphere. They listen to a lecture on the carbon cycle while drawing an example of the carbon cycle on the board. Students comprehend that CO2 is...
