Web and Food Chain Lesson Plan

Students will discuss food webs and how animals interact in the biosphere. Also they can make an oceanic food web model.

That Class plan about food webs were specially developed to teach students in an easy and interactive way. Check out:

Goal: Students will discuss the food webs and how animals interact in na biosphere. In addition they can make a web model that shows how animals get their energy of other animals and the sun.

Necessary materials:

• Yellow paper for students to make small three-dimensional suns (can be scrap paper or white paper painted yellow);
• Bookmarks;
• Crayons or coloring pencils;
• Pencil;
• Writing paper, etc.

Lesson

• Read a book about the ocean.
• If no books are available: Draw or project a picture of a shark onto the board.
• Ask students where sharks get their energy.
• Lead a discussion about how predators like sharks, humans, lions get their energy.

During the class

• Explain to students that there are some living things on Earth that do not consume food for energy. Ask if they can think of any examples. (plants)
• Ask students where plants get their energy from.
• Explain that plants get their energy from the sun.
• Tell students that there are some special plant-like creatures in the ocean that also get their energy primarily from the sun. They are called phytoplankton.
• Write the word phytoplankton on the board. (Be prepared for comments about SpongeBob's plankton)
• Ask students if they know which animals eat phytoplankton. (krill, among others)
• Write krill on the board and explain that many small fish depend on krill, which are small shrimp-like animals. (Whales also eat krill, but for the purpose of the food chain leading to the shark, you don't need to focus on the whale for this lesson.)
• Explain that fish eat krill.
• Ask students which animals eat fish. (Many animals eat fish, but be sure to talk about seals.)
• Ask students which animals eat seals. (Sharks)

guided practice

Students can write a summary of the day's activity using the new words they learned. The summary can be more elaborate or simpler, based on the class writing program.

Example: “The ocean is an interesting place for many reasons. There are many predators in the ocean that look for prey to eat. Sharks like to eat seals. Seals like to eat fish. Fish like to eat krill. Krill like to eat phytoplankton. Phytoplankton get their energy from the sun and other minerals in the ocean.”

Closure

Students can read their writing and discuss the activity using class vocabulary.

Assessment

Students will make a model showing how ocean animals interact in the energy food chain.

Differentiation

The teacher can work with students in small groups to accommodate those who need extra assistance. Students who are reluctant to participate can work with a partner. The teacher can provide both verbal and physical cues to help students.
