Though the walrus spends roughly one third of its time on land, it eats organisms that live on the bottom of the ocean. The first in a series of five, the lesson uses a variety of plant and animal cards to have scholars build an arctic...

A brief comparison of human teeth versus animal teeth sets the stage for two worksheets. Scholars match a picture of a tooth-filled mouth to the animal to which it belongs and coloring pages featuring a different animal and informative...

Mammals have unique interactions with their ecosystems. Using a multi-part lesson, learners research local mammals using recommended websites and use their findings to create their own paper ecosystems including appropriate mammals. They...

You are what you eat—or at least a part of what you eat. Budding scientists examine owl pellets to develop their own food webs. They use tooth and skull identification techniques to classify what they find.

Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...

Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...

As the saying goes, you are what you eat. A useful set of lesson plans encourage young readers to take a second look at their eating habits. Pre- and post-reading questions bring in reflective writing and discussion while extension...

When 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...

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.

Tooth be told, your class is gonna love this video! Science scholars look beyond simple cell types and enter the world of teeth. The narrator describes how we think teeth evolved to their present form, how form dictates function, and how...

Learn more about food chains, the food web, and the concepts relating to them. It focuses on consumers, producers, decomposers, energy transfer, and energy loss across trophic levels.

In spring, the Bering Sea turns green due to phytoplankton, which live at the surface, experiencing a population explosion. Groups of scholars play a food chain game, writing down food chains as the game is played. After five to six...

How does one organism get its energy? What is the main source of energy in an ecosystem? How does the flow of energy affect different types of ecosystems? Answer these questions with a fill-in-the-blank worksheet. 

How do different types of living things get the energy they need? This is the focus of a video that describes how carnivores, herbivores, and omnivores get the energy they need to live.

Why do we eat? We eat because we need energy, and humans need energy to grow. This is the focus of a video that explains why organisms need food to live.

Whether your young biologists realize it or not, humans play a significant role in marine ecosystems. To help them understand this fact children first create graphical representations that show homo sapiens' place in marine food chains,...

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,...

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...

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

What can teeth tell us about an animal's diet? Learners examine animal skulls to determine what their canines, incisros, premolars, and molars reveal.
