The
student will investigate and understand that plants produce oxygen and
food and are a good source of useful products.
Key concepts include:
- important plant products (fiber, cotton, oil, spices, lumber, rubber, medicines and paper)
- the availability of plant products affects the development of a geographic area
- useful purposes of plants (provide homes and food for many animals and prevent soil from washing away)
Plants contain cellulose, which is used to make paper and clothing (fiber and cotton).
Their wood is used as a fuel source and for lumber for houses and furniture.
Plant parts are also used in other commercial products, including paint thinner, rubber, chewing gum, spices, oil, and medicines.
Students should be able to:
- Classify and identify the sources and uses of plant products such as fiber, cotton, oil, spices, lumber, rubber, medicines, and paper.
Plants may only grow well in certain geographic areas, thus enabling the production of plant products that allow humans to live in, as well as develop, those areas.
Many living things depend on plants for the oxygen they produce.
Many living things use plants as a source of food (fruit, nuts, berries, spices, herbs, vegetables).
Plants provide homes (shelter) for many animals.
Plants are also important in preventing soil from washing away.
Students should be able to:
- Comprehend that plants produce oxygen and food.
- Describe plant products grown in Virginia that are useful to people including wood, fruits, and vegetables. List and classify plant products.
- Construct and interpret a chart illustrating the plant foods consumed by different animals.
- Compare and contrast different ways animals use plants as homes and shelters
- Construct and interpret a model that demonstrates how plants prevent soil from washing away
