My Burrow - Our Burrow!:

"…Everything affecting the gopher tortoise's habitat affects the tortoise and … eventually affects all other organisms in its ecosystem. Efforts to save the gopher tortoise are really a manifestation of our desire to preserve intact, significant pieces of the biosphere. …We must preserve…the gopher tortoise and other species in similar predicaments, for if we do not, we lose a part of our humanity, a part of our habitat, and ultimately our world." — Dr. George W. Folkerts, "The Gopher Tortoise: A Species in Decline"

The gopher tortoise of the southeastern United States is a reptile that creates and lives in a subterranean burrow primarily in dry upland habitats. The are also found among coastal dunes. More than 350 species depend upon the gopher tortoise burrow for protection from temperature extremes and periodic fires. The fires, in turn, ensure that the canopy is open for plentiful sunlight. Low growing vegetation is the tortoise's primary diet and depends on open sunny areas. The animal species living in the burrow are known as commensals and include hundreds of invertebrates and vertebrates that would not survive without the burrows these tortoises create. This lesson is designed for students to deepen their understanding about symbiotic relationships and, most importantly, learn that the removal of a keystone species (the gopher tortoise) affects the entire food web of the habitats in which these inhabitants exist.

Students will, with help of the teacher, till the ground with removal of ground cover, build border for garden, add soil, attach poles with string to create a life size graph all so they can grow tomatoes and plot the data easily in their survival journals.This is Part 2 of a 4-Part Project on Survival.

Survival of the Fittest:

This is a five day lesson integrating Science, Reading and Writing. It is developed on a Reading lesson plan format using Shared Reading, Core Reading, Guided Reading and centers but can easily be transferred on to a Science 5E lesson format. The versatility of the lesson and the integration between subjects lends itself to it being widely used among teachers for different reasons; whether the teacher's need be in Science, Reading or Writing the lesson provides opportunities for all areas to be addressed. Most importantly, it offers the busy teacher an opportunity to implement one lesson to cover three subjects.

Type: Lesson Plan

Symbiotic Socializing:

Students will collaboratively work towards understanding symbiotic relationships in various ecosystems. Activities include KWL chart, short Youtube Clip, Symbiotic Sea Social, Symbiosis Scavenger Hunt, Symbiotic Style Four Corners, and creating a cumulative Symbiotic Diagram of an ecosystem of students' choice.

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.
