Unit 3 Kelp Forest

Unit 3:

Kelp Forest

Discovery Education

Activity 1

Objective

I can develop a model to explain how kelp density can change in a kelp forest.

Poll

Have you ever seen or touch kelp before?

• Yes

• No

• I do not know

In this unit

In this unit, your job is
to figure out why the
kelp forest that Paloma
observed did not have
much kelp in it.

Exploring Kelp Forest Observation

While watching the video, observe the amount of kelp present in both kelp forests.

Video Time

Open Ended

Please provide four observations, two for each kelp forest seen in the video. Please let me know if you need any further clarification.

Modeling the Anchor Phenomenon

Now you will work together in a small group to develop a model to show each of
the two different kelp forest ecosystems. Think about how you will show the
relationships among the organisms in a kelp forest in your model. Discuss your
ideas.

Draw

Illustrate the differences between the two kelp forest.

Open Ended

Now that you have seen and compared different models, write a list of everything the models have in common. Your list must include at least 3 things

What Did You Figure Out Today?

Constructing an initial model can help you communicate what you already know
about ecosystems and uncover ideas you may not fully understand about
ecosystems and the interactions that take place there.

Open Ended

Write two things you
figured out today and one question you have about kelp forests.
