Using an underwater viewer enables you to discover much about life underwater without having to catch any animals. You can use the viewer in a stream, lake or in tide pools. Here's how to make one!
What you’ll need
- A large can or pop bottle
- Clear plastic
- Strong elastic bands
- Scissors, x-acto knife or can opener
What to do
1. Carefully take the top and bottom off a tin or a plastic bottle (get an adult to help you). Make sure there are no sharp edges.
2. Fix the clear plastic tightly to one end with an elastic band.
3. Push the plastic end into the water and look through it.
Now you can explore the underwater world with your scope! Depending on the type of aquatic environment you are looking at (for example, freshwater or marine, still water like a pond or moving such as a stream), you will be able to see different underwater animals. Make sketches of your observations and see if you can identify the creatures using aquatic animal guides. The types of animals found in an environment can also give us clues as to the health of the environment. For example, stone fly larva are very sensitive to pollution and if you find them in a stream, the water is very clean.
