Renewable/Non-renewable Resources Activity

Do Now How are these car engines different? How are they the same? Which is better for the environment? How do you know?

There are 2 types of energy What are they?

Renewable Energy Resources

Non-renewable Energy Resources

What is a renewable energy resource?  Renewable energy is natural energy which does not have a limited supply.  Renewable energy can be used again and again, and will never run out. Types:  Biomass  Hydro-electric  Geothermal  Solar  Wave  Wind  Wood

What is a non- renewable energy resource?  An energy resource that is not replaced or is replaced only very slowly by natural processes  Fossil fuels are continually produced by the decay of plant and animal matter, but the rate of their production is extremely slow, very much slower than the rate at which we use them. Types:  Coal  Oil  Nuclear  Natural Gas

Make a concept map differentiating between renewable and non-renewable as ENERGY RESOURCES

Do Now: Give 2 examples of renewable energy and 2 examples of non- renewable energy

TARGET GOALS  SWBAT… (STUDENTS WILL BE ABLE TO…)  Understand how population relates to energy resources  Evaluate problems related to resource availability  Discover differences between renewable and nonrenewable energy resources  Learn strategies to prevent resource depletion

What are Natural Resources?  All of the things we use in our physical environment to meet our needs and wants.  Water  Land  Material for clothing  There are 2 types of Natural Resources  Renewable  Non-Renewable

Non-Renewable Resources Exist in FINITE amounts Once they are used up, they are gone FOREVER!!! For example, fossil fuels are formed through natural processes that take MILLIONS of years. If we use all of the available fossil fuels, no additional amounts of them will EVER be available to us – at least not for MILLIONS of years!!!

Renewable Resources  Can be replenished through natural and/or human processes.  For example, even though trees die and are cut down, new trees are naturally reseeded or can be replanted by humans.  Solar energy, wind, and tides are renewable resources that are constantly being renewed or restored.

Sustainability  the ability to be sustained, supported, upheld, or confirmed.  In Environmental Science, it’s the quality of not being harmful to the environment or depleting natural resources, and thereby supporting long- term ecological balance.

Sustainable Yield  The maximum rate at which people can use a RENEWABLE RESOURCE without reducing the ability of the resource to renew itself.  For example, sustainable yield of timber would mean harvesting only the volume of trees that the forest could grow.  Sustainable Yield also applies to water and wildlife.  It varies from region to region and is different depending on the resource.

Follow-Up Questions Categorize the following as renewable or non-renewable  A field of corn  Oil in the Arctic tundra  Coal in the Appalachian mountains  Sunshine  Trees in a forest  Tuna in the ocean  Sand on a beach  A breeze over the Texas plains  Water in a river  Which resources would continue to be available no matter how much people used them?  Under what circumstances would a renewable resource not be renewable?
