| Write the word resource on the board. Review with the
students the meaning of a resource. A resource is something people use
to meet a need. The natural features of the Earth are land and water.
Land and water are used as natural resources. Tell the students that one
way we use natural resources is for recreation.
|
| Pull down the Landscape Picture Map. Have the students locate the
lake and the river. Ask the students to describe some of the ways they
can have fun on lakes and rivers. (Examples might be swimming, boating
and fishing.)
|
| Ask the students if they would enjoy swimming more in a clean or
dirty lake. How do lakes or rivers become dirty? List the student
responses on the board.
|
| After the discussion, tell the students that when people throw
things into a lake or river they are causing pollution. Pollution is the
act of making your surroundings unsafe or dirty. Write the word
pollution on the board.
|
| Ask the students: Who is responsible for keeping the lakes and
rivers clean? Is it the police, fire department or each person?
|
| Conclude the lesson by suggesting ways people may keep lakes and
rivers clean and safe. |
