TN COMPONENT OF SCIENCE: Unifying Concepts of Science
BENCHMARK: The form of a structure implies its function. The function of a structure tends to dictate its form.
All living things get their energy from food. A food chain is formed as one living thing eats another. Food chains begin with plants. A pond food chain could begin with lily pads. Dragon flies eat lily pads. Fish eat dragon flies. Men eat fish.
There are two kinds of things that make up a food chain. A producer is a living thing that makes its own food. A consumer is a living thing whose food comes from other living things. Food chains vary due to the environment within the habitat. Sometimes changes occur to disturb the natural habitat of animals. Habitat is a special place where a particular population lives. Sometimes an animal's natural habitat can be destroyed by man's poor planning or carelessness. Often man can help nature by building new habitats for animals or protecting the existing ones. This can be done by building parks, wildlife preserves, and zoning land as wilderness areas. Why would we want to protect these habitats? (so they do not become endangered) Endangered animals and plants are scarce. That means there are not many of them.
Living things can become endangered when many of one kind die. There may be a shortage of food. A certain disease may cause plants or animals to die.
People can cause living things to become endangered. They can destroy plant and animal habitats.
2. Discuss where state or national parks are located and why. How do they protect the environment?
3. Write a report on "Why the natural habitats should be preserved." (Display or read to the class).
4. Conduct a field trip in a nearby open field to locate habitats. Identify life forms in that habitat. Do not bother the animals or the habitat.
2. Examine the zoning regulations of the community.
