How we explain it

Children can open this short lesson before they practice.

  1. Natural resources come from nature: water, trees, rocks, soil and oil.
  2. People use them to build, farm, travel and make things. Wood comes from trees.
  3. Conserve them: reduce, reuse and recycle. Floods and droughts can change habitats.

Example: Gasoline for cars is made from…? It is a fuel pumped from underground. Answer: oil
