Energy Transferthe strength and vitality required for sustained activity that is passed from one organism to another.

Misconceptions* Students think organisms contain cells.* All cells look alike.

K-2: Introduce the food chain. Teachers can use recycling to help students understand matter is present even if it changes forms.3-5: Model circular food chains with plants, herbivores, and omnivores to show how each organism extracts and uses energy.Middle School: Students need to study food chains and webs in greater depth so they can make connections between the collapse and reassembly of matter.**Students need to understand matter does not just appear or disappear.

Teaching Strategies

K-2: Provide students with magnifying glasses, and have them study plant and animal cells.3-5: Use low powered microscopes to study organisms.Middle School: Use microscopes to compare human, animal, and plant tissue to connect cells to the building blocks of life.

Teaching Strategies

Misconceptions*energy disappears once an organism dies.* food webs involve creation and destruction of matter

Truths:*Organisms are made up of cells.*Different organisms have different types of cells.

Truths:*Energy is passed from one organism to the next. *Matter coolapses and reassembles
