Young scientists weave together an understanding of ecosystems with this fun collaborative activity. Taking on the roles of different living and non-living elements of specific habitats, learners use a ball of yarn to create the web of...

Young scientists learn what it takes for life on Earth to survive with this series of photosynthesis resources. Offering twelve different activities ranging from independent practice worksheets to in depth scientific experiments, this...

What better way to learn about ecosystems than by getting outside and observing them first hand? Accompanying a field trip to a local park or outdoor space, this series of collaborative activities engages children in learning about the...

Hidden hundreds of feet above the ground in the redwoods of Northern California is a whole world that was just waiting to be discovered. This video tells the story of Stephen Sillett who, inspired by his grandmother, set out to explore...

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready to start...

Young scientists explore nature's water treatment plants in this simple science demonstration. By placing a stalk of celery in a cup of water mixed with food coloring, children are able to observe how plants absorb nutrients and...

One of the key concepts in life science and biology is the cycling of energy throughout an ecosystem. Learners can take notes on the topic using the vocabulary included within the presentation. From producers making their own food...

Krill is a very small ocean animal that is key to keeping the ocean ecosystem going. The class reviews food webs and chains, learns about the importance of krill, discusses krill anatomy, builds a model of a krill, and then has a...

Does your class know that all water that falls from a watershed ends up in the same large waterway? If they don't, they will after they complete this activity. They make a clay model of a landscape that looks similar to a topographical...

Creating an ecosystem is as simple as baking a cake. Well, maybe not, but using a recipe analogy helps learners realize that ecosystems consist of different components that come together in unique ways. Offer this learning exercise as an...

Starting with a simple food chain, young scientists interpret the difference and interrelatedness between herbivores, carnivores and producers. They answer questions related to cause and effect of food chain disruptions, including the...

A food web consists of complex food chains and the more complex the web, the better likelihood of survival. Learners compare and contrast food webs and food chains and discuss concepts like the predator-prey and consumer-producer...
