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...
Deep-Sea Ecosystems – Entering the Twilight Zone
5th - 6th CCSS: Adaptable
Imagine an ecosystem without any light or oxygen, where living things convert carbon dioxide into food. This ecosystem is thriving and might just be the largest ecosystem on our planet, yet we know very little about it. The lesson...
Breaking Down Ecosystems
6th - 8th
Ecosystems are crucial in allowing for the flow of energy. In this collection, learners look at how energy flows from one organism to another through food chains and food webs. With videos, interactives, and worksheets, the material in the collection is great for a week long study of ecosystems. The end of the collection provides a quiz for young life scientists to show what they learned.
Ecological Pyramids interdependence, food chains, food webs, trophic levels
4th - 8th CCSS: Adaptable
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.
Construction of Food Chains and Tracing Energy Changes
5th - 9th
If you need a few basic activities for teaching food chains to your emerging ecologists, here they are. Three sheets of organism cards are included for learners to cut out and arrange according to trophic relationships. To make the most...
