Expose your class to the steps of the nitrogen cycle with this short clip. Colorful computer imagery and animation explain how nitrogen travels from the atmosphere as a gas into plants and soil, where bacteria convert it into nitrates....

Take a ride on the carbon cycle by watching this animated featurette. Those who do will learn about the element carbon, how it cycles through the atmosphere and biosphere, and how it contributes to Earth's temperature. This video comes...

Explore various ecosystems from around the world as your class discovers the interdependence of all living things. Using the provided sets of ecosystem cards, young scientists work in small groups building food webs to demonstrate the...

During a three-part lesson, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which is...

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

With the forest as an example, Sam and Zoe talk about the components biotic and abiotic of an ecosystem. They also discuss the role of producers, consumers, and decomposers. This concise clip covers all of the basics. As an introduction...

Mia's friends are fish-sitting while she is away on vacation. Zoe divulges to Sam that different animals need different habitats, and that there are both freshwater and saltwater ecosystems. Examples of the kinds of organisms found in...

Rhinozilla is back to take your lesson plan on trophic levels a step higher! After showing the video on food chains (available through the See All Related Jams button), add to it by showing this one. It deals with omnivores and food...

Strengthen understanding of the musculoskeletal system with a structured lesson! Begin with a discussion of bones, joints, and muscles. Have small groups read assigned articles and watch videos to gather information and then write a...

Pump up your class while studying the cardiovascular system with this pair of activities. In one, learners record heart rates during different actions. In the second, they read kid-friendly heart health articles online and then write a...

With articles entitled, "What's Puke?" and "What is a Fart?" this digestive system lesson is sure to be a gas! Elementary anatomists do a belly dance to illustrate how food moves through the digestive system and then design a board game...

Changes to habitats mean changes to resources. Groups examine aerial maps to predict areas of low and high plant resources. After formulating a plan, they visit the areas to collect data about the plant resources and then share their...

Leaf toughness can add to its herbivore appeal. Learns design an experiment to quantify leaf toughness and then perform their procedures. They follow the experiment with a set of questions that ask them to think about how leaf toughness...

It is a tangled web the ecosystem weaves. Learners begin an activity on ecosystem interactions by building a food chain and then a food web with yarn as a group. To finish, they research local environmental changes that may impact the...

The class studies the soil food web that includes earthworms and conduct four experiments using the crawly critters. Individuals determine whether earthworms are sensitive to light, touch, temperature, and acid.

Twenty questions make up an assessment designed to test super scientists' knowledge of ecosystems. Scholars answer multiple-choice and short-answer questions about organisms, food chains, energy flow, and more.

Thirteen short-answer questions follow a brief food web activity in a formative assessment designed to test knowledge of ecosystems and the energy that flows through them.

Budding scientists work collaboratively to reenact energy flow in a food chain. Scholars take on roles such as producer and consumer and perform tasks that symbolize energy flow in order to provide evidence of how much energy passes...

Get your hands dirty with an interactive lesson plan that showcases the process of decomposing and returning nutrients back into the soil. After building a compost pile, pupils regularly observe the ways worms help with changes to the...
