Underwater Viewer Experiment

On May 10th, Room 8 went out on their very first scientific expedition to find out what sat at the bottom of the sea. Underwater viewers were designed and constructed to help with Room 8’s discovery. The purpose of the underwater viewers were to see things clearly beneath the water.

Our location was set at the Tamaki River. The seabed was muddy and surrounded with mangroves and mudflats. Some of the areas were easy to walk on while other surfaces were more difficult since there weren’t a lot of shells which meant it wasn’t as firm.

A lot of creatures were found on the mud including shrimp, crabs, sea slugs and sea snails which were mainly found underneath rocks. Some sea creatures left behind shells which were scattered along the areas we were examining in. Non-living items including tyres, pipes from drains, broken glass and rusty chains from the boats were also found.

The difficulty of this expedition was reaching the waters edge because at the time we experimented the tide was low. The closer we came to it, the mud became softer to a point where we got stuck. Our underwater viewers weren’t used during the expedition. If the tide wasn’t low that day, the area where we found things would have been under the water. Without the help of our device we still discovered what sat at the bottom of the sea.
