Ecosystems: Energy Flow

Ecosystems: Energy Flow

7th Grade Science

Opening:

-Review Digital Expectations

-Standard

-Essential Question

-Learning Target

-Phenomena Activity

Digital Expectations:

--Be on time

--Participate in the lesson

--Make sure your sound is on

--Follow the Student Code of Conduct

Standard:

S7L4--Obtain, evaluate, and communicate information to examine the interdependence of organisms with one another and their environments. (b) develop a model to describe the cycling of matter and the flow of energy among biotic and abiotic components of an ecosystem. 

Essential Questions:

-How does matter and energy flow through an ecosystem?

-How can we model the flow of matter and energy through an ecosystem?

Learning Target:

By the completion of this lesson, I will be able to describe and model the flow of energy in an ecosystem.

Energy Transfer Phenomena

-Next, we will watch a video of a caterpillar. As you watch, notice what the caterpillar is doing. How do you think the caterpillar is able to transform? What does the caterpillar need?

Food Chain Model

-Food chains start with producers and the chain continues with organisms that consume the previous organism.

Food Chain Practice

--We will complete Food Chain practice models using the website on the following slide.

Food Web Model

-Many FOOD CHAINS make up a FOOD WEB. (See how many different food chains can make up a food web?)

--We will complete a Food Web model using the website on the following slide (Click on the "Open in New Tab" link.)
