New ReviewWhen a minnow eats a piece of plastic, that garbage often tracks through multiple animals, causing harm to each as it passes through the food chain. Scholars learn about food chains, food webs, and energy pyramids with a presentation. It...

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...

Our relationship with toxins is, well, a little toxic. Explore how harmful substances work their way throughout the environment with a video from an expansive biology playlist. Topics include DDT and mercury, trophic levels, and water...

Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

A video starts by defining an ecosystem. It expands on the concept by covering trophic structure, primary producers, primary consumers, secondary consumers, tertiary consumers, detrivores, and bioaccumulation. 

Entangle your life science class in learning with this collaborative food web activity. Using pictures of the plants and animals native to a particular ecosystem, young biologists work in small groups to construct visual representations...

Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-activity series. Building on prior knowledge about producers, consumers, and decomposers learners are introduced to the concept...

Jump into an exploration of marine ecosystems with the first lesson plan in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

Transform young biologists into grasshoppers, lizards, and hawks as you teach them about food chains in an interactive life science simulation. Working collaboratively to act out three different scenarios involving these creatures,...

For as small as they are, plankton sure play an enormous role in maintaining marine ecosystems. Dive into an investigation of these tiny organisms with a hands-on life science activity in which children cut out pictures of sea animals...

From bears and owls to chipmunks and trees, all life depends on the sun for the energy to survive. Young biologists develop an understanding of this big idea as they arrange this series of plant and animal picture cards into food webs...

Young scientists explore the interdependence of organisms with this simple life science activity. Using the provided template, students create and label tiered pyramids that model the hierarchy of trophic levels in ecosystems.
