Rubber
Rubber is a natural polymer made from the sap of the rubber tree, Hevea brasiliensis. It is an elastic material that is used in a wide variety of products, from tires to rubber bands to waterproof clothing.
Properties of Rubber:
- Elasticity: Rubber can stretch and return to its original shape.
- Flexibility: It is flexible and can be bent or twisted without breaking.
- Insulation: Rubber is a good insulator, which means it does not conduct electricity well.
- Waterproof: It is resistant to water and is often used in waterproof products.
Uses of Rubber:
Rubber is used in a wide range of products, including:
- Tires for vehicles
- Rubber bands
- Shoe soles
- Gloves
- Seals and gaskets

LIFE SCIENCE
Ecosystems: Interactions, Energy, and Dynamics
Obtain information from literature and other media to illustrate that there are many different kinds of living things and that they exist in different places on land and in water (e.g., woodland, tundra, desert, rainforest, ocean, river).
EARTH AND SPACE SCIENCE
Earth’s Systems
Make observations from media to obtain information about Earth’s events that happen over a short period of time (e.g., tornados, volcanic explosions, earthquakes) or over a time period longer than one can observe (e.g., erosion of rocks, melting of glaciers).
Collect and evaluate data to identify water found on Earth and determine whether it is a solid or a liquid (e.g., glaciers as solid forms of water; oceans, lakes, rivers, streams as liquid forms of water).
