Science - 4th Grade
Standard 5 Objective 2
Students will research and report on an endangered Utah species.
Some people do not understand or care how actions of the human race is destroying species of animals and plants in Utah. There are many species that are endangered, threatened or have special concerns that could be extinct if measures are not taken. The following are terminology and definitions from the US Department of Wildlife to help your understanding of these endangered species.
Extinct: a wildlife species that has disappeared from the world.
State Endangered Species: any wildlife species which is threatened with extirpated from Utah or extinction resulting from very low or declining numbers, loss of habitat, environmental changes, or a combination of the above. Continued long-term survival is unlikely without the implementation of special measures.
State Threatened Species: any wildlife species which is likely to become endangered within the foreseeable future.
Most of these species have become endangered and are close to extinction because the loss of habitat has affected them. As the human race grows, so does the need to expand. This expansion is taking over more and more land. The more land we take over, the less land the animals have. Animals are not only losing their homes, but also their food and protection. Some animals cannot adapt to new environments very quickly, so their litters are getting smaller. With smaller litters, there is less food in the food chain. People need to start recognizing the problems and state coming up with solutions that can benefit all animals in this world.
1. Use science process and thinking skills
2. Manifest scientific attitudes and interests
4. Communicate effectively using science language and reasoning
Pre-Assessment/Invitation to Learn
Tell the students that while they are out to recess, something will be happening that will benefit all people. While the students are out to recess, mark off one-half of the room with masking tape. Place a construction sign that reads: Development site: The land will be cleared for this site has been zoned for a new mini-mall. No one is allowed to enter.
Over by the students' lunches and backpacks, mark another area off with masking tape. This is so the students will think that they will not be able to eat lunch. Place a sign that says: New construction: Land will be cleared for a new parking structure. No one is allowed to enter.
As the students come in from recess, there will be a lot of commotion. Have the students sit in the remaining area and start a discussion about the construction. Ask: How do you feel? Is it crowded in the room? What do you think will happen at lunch time? If you were an animal, what would you do for food, water, shelter and protection? What happens when the food and water run out? Can everyone find shelter or protection? What will happen if you can't?
