Renewable/Nonrenewable Resources
What will we be learning today?

  • In this lesson, we are going to learn all about renewable and nonrenewable resources and conservation.

  • Why recycle - because environment provides the materials people use to make products.

  • The paper to make books, magazines, newspapers and containers come from the wood in trees

  • Metals mined from the ground are used to make cars, ships, pots and pans, appliances and many other things

  • Glass is made from sand

  • Plastics are made from chemicals in oil found deep underground

  • Wood, metals, sand, and oil are called raw materials

  • Many raw materials, such as oil and metals are nonrenewable resources

  • Earth's oil was formed millions of years ago and there is limited amounts of it

  • When it's gone, it's gone forever!

  • Other resources, such as wood, are renewable resources

  • If tree are cut down for lumber and paper, more can be planted to replace them

  • But trees take years to grow

  • Recycling paper and other wood products can help keep forests from being destroyed

  • It also can help keep animals from losing their homes and from facing extinction

  • Minerals are nonrenewable resources - they can not be replaced

  • Since minerals are nonrenewable resources we need to conserve them

  • Conserve means to "use wisely or avoid waste"

  • One way people can help conserve is by recycling - to use them again

  • Nonrenewable Resources- a resource that cannot be replaced within a short period of time      or at all

  • Renewable Resources- a resource that can be replaced in a short period of time

  • Recycle - to reuse them

  • Conserve - to save, protect, or use resources wisely

  • Raw Materials - materials not yet refined, manufactured, or processed
