Lesson Plans

Arctic Algae :

In this lesson, students will analyze an intended to support reading in the content area. The article explains how climate change is reducing the amount of sea ice in the Arctic Ocean. Within this sea ice is found algae that forms the base of Arctic food webs. As the sea ice goes, so does the algae, which in turn could affect the entire Arctic ecosystem. This lesson includes a note-taking guide, text-dependent questions, a writing prompt, answer keys, and a writing rubric.

Holy Jumping Earthworms, Batman!:

In this lesson, students will analyze an informational text that shows how a seemingly harmless invasive species of jumping worm may cause much more destruction than once thought. The Asian jumping worm eats the debris on the forest floor at a rate that out-competes the native worms so much so that it is causing a number of problems, including forest re-growth. This lesson plan is designed to support reading in the content area. It includes a note-taking guide, text-dependent questions, a writing prompt, answer keys, and a writing rubric.

Go with the flow:

This lesson uses everyday household materials to provide students with a visual representation of the energy flow through an ecosystem, emphasizing the inefficiency of this energy transfer. It provides students with the opportunity to calculate the amount of energy available for transfer between organisms integrating math into your lesson while the extension activity allows students who are stronger in language to shine as they create a newspaper article.

Type: Lesson Plan

Web vs Web:

Students will compare and contrast food webs from two different underwater ecosystems - one that uses the sun as energy source and one that uses an alternative energy source.

Type: Lesson Plan

Tangled Web and a Missing Organism:

Students will participate in an interactive activity in small groups. After briefly finding out what their organisms consume or what consume them, students will physically connect organisms using string and pushpins. Once the web is tangled, you will go around and designate a "removed" organism. Students will follow all the strings attached and explain how the connected organisms are affected. Eventually, in the mist of the class discussion, students will realize that the entire ecosystem is affected.

Algae Embedded in Sea Ice Drive the Arctic Food Web:

This informational text resource is intended to support reading in the content area. Species that live in the open ocean may suffer as sea ice disappears. As sea ice disappears, the algae embedded and living in the sea ice will be reduced. This article explores the evidence collected to show the role of algae in driving the Arctic food web.

Earthworms: Can These Gardeners' Friends Actually Become Foes?:

This resource is designed to support reading in the content area. The article describes new research on the ways Asian jumping worms are affecting American forests. Findings show they are much more of a problem than initially feared. Because Asian jumping worms have bigger appetites than other earthworms found in the U.S., they are much more successful at eating the debris on the forest floor. This exposes vulnerable areas that may bring more diseases and invasive plants. It can also prevent delicate seedlings from taking root.

The Ecological Cost of Dinner:

This lesson is about the flow of energy in ecosystems. The setting is Plimoth Plantation, a living history museum in Plymouth, Massachusetts, USA, where students will learn about the first Thanksgiving meal in America, celebrated in 1621 by early American settlers and Wampanoag Indians. By examining this meal and comparing it to a modern day Thanksgiving celebration, students will be able to explore the way in which food energy moves and is transformed in an ecosystem. The learning goals focus on the movement of energy from one feeding level to the next within a food web, the way in which energy changes form, and the inefficiency of energy transfer, which in turn affects the availability of food energy for organisms at the highest feeding level. The lesson is directed at high school level biology students. Students should be familiar already with food webs, food chains, and trophic (feeding) levels. They should also be familiar with the general equations for photosynthesis: 6H2O + 6CO+ Energy(light) -> C6H12O6 + 6O2 and cell respiration: C6H12O6 + 6O2 -> 6H2O + 6CO+Energy(about 38ATP), and understand the basic purpose of these processes in nature. This lesson can be completed during one long classroom period, or can be divided over two or more class meetings. The duration of the lesson will depend on prior knowledge of the students and on the amount of time allotted for student discussion. There are no supplies required for this lesson other than the downloadable worksheets (accessed on this BLOSSOMS site), paper and some glue or tape.

Deep Sea Vents and Life:

Excerpted from NOVA: "Volcanoes of the Deep", this video segment reveals strange and luminescent forms of life, such as giant tube worms, spider crabs, and billions of microbes clumped together like a cottony web. The site where life began on Earth may have been where black smokers stream from hydrothermal vents and chimneys along the sea floor.

Decomposers:

This video segment from Interactive NOVA: "Earth" describes the role of decomposers in the living world. We've all been victimized by decomposers: Lettuce rots; bread becomes moldy. Bacteria and fungi often consume our food before we have a chance to. However, if we stop to consider the important work that decomposers do, we may be a little less disgruntled by their presence.
