What's going on underwater? Sometimes it's hard to see when
you're peering in from the outside.
You can make an underwater viewer to see what's really going on
under the surface.
What you need:
- Plastic tube or plastic milk carton
- Cling film or other clear plastic
- Scissors
- Elastic band
How to:
Be very careful around water . Always make sure someone
knows where you are.
- If you're using a milk carton, cut the top and bottom off. Make
sure there are no sharp ends. If you're using a plastic tube, it
should already have the top and bottom cut off.
- Stretch cling film or clear plastic tightly over one end of the
milk carton or tube.
- Attach the cling film with an elastic band. Make sure it is
watertight.
- Find a pond or lake that you can look at. Put cling film
covered end under the water and look through the other end. What
can you see?
With your underwater viewer you can look under the surface
without getting your face wet!
Try looking at different areas of the pond or lake. Can you see
different things in each part? What animals can you see?
