K-2

M3: Identify commonly used resources, their sources, and where waste products go.

Curriculum Organizing Questions

What things do we get from the living environment that you use everyday?

When the things that we use everyday are no longer useful, where do they go?

Where do we get the materials to make this from? Where does it go if you throw it away?

Elaboration
This is not intented to be an in-depth analysis of materials, or a study of decomposition. Students should simply be encouraged to wonder where things come from and where they go.

Specific Ideas

People burn fuels such as wood, oil, coal, or natural gas, or use electricity to cook their food and warm their houses.Benchmarks 8C2.

Resources are things that we get from the living and nonliving environment to meet the needs and wants of a population.NSES F3a.

Some resouces are basic materials, such as air, water, and soil; some are produced from basic resources, such as food, fuel, and building materials; and some resources are nonmaterial, such as quiet places, beauty, security, and safety. NSES F3b.

Some materials can be used over again. Benchmarks 8B4.

Developmental & Instructional Implications
At this age lessons should be strongly tied to the immediate world of home and school.

Examples
Aluminum is found in special rocks and used to make lots of things like cans. If you throw a can in the trash, it will go to a landfill or to an incinerator facility. If you recyle the can, it will be melted and made into another can or something else that is useful.
