- Observe fish in a fish tank. Movement, fins, gills, eyes, mouth, sleeping, eating, interaction with other fish. Note that is living in water.
- Alternatively, purchase a whole fish at the market. Observe body structure, color, iridescence, scales, inside mouth, teeth, gills, fin and tail structure. It is possible to cover with a thin layer of paint, and press on paper to make a print. When dry, label the various parts.
- Animals have features that help them live in different environments. A fish's body is perfectly suited to life underwater, just as our bodies are suited for life on land.
- Fish live under water. Can people live underwater? Why? Then how can fish? We have lungs to breathe air (oxygen), and fish have gills to extract oxygen from water.
- We have legs to go places. How do fish get around? Talk about fins and tail movement in water.
- Fish are not mammals, so they do not have live babies. They lay eggs. (Show photo).
Have the children draw a large outline of a body and tail on paper. Cut it out and decorate with tissue fins, bright markers and glitter. You can make it 3 dimensional by stapling or taping a backing, and stuff it with bits of newspaper.
- Create flying fish for counting games: fill old socks with lima beans or similar, tie it closed with a knot. Throw at a target, or into a container.
- Crayon resist: draw colorful fish etc. with crayons; paint over with a thin layer of turquoise watercolor.
- Counting sets of goldfish crackers on to paper fish bowls.
