THIRD+VISIT

__**Free Journal Entry #3**__

This time when I went to Manoa Stream, some things have changed from my last visit. The greatest significant difference is that this time it was raining a lot harder than any other visit I’ve had. This caused the current of the stream to rapidly increase downstream. The current was so rough that the ducks couldn’t go up the stream and were compelled to follow the direction of the current. During my visit, we also saw a tree lying on the ground that looked like it had been blown down by the heavy winds.

However, I was still able to take pictures and make observations for my hypotheses. One testable hypothesis I came up with is that IF the water is calmer THEN there will be more ducks and fishes living in the stream. This is a testable hypothesis in which I can observe and record the number of ducks and fishes living in the stream when the water current is moving rapidly. Then, observe and record the number of ducks and fishes when the water current begins to decelerate. Another testable hypothesis I came up with is that IF there were less pollution in the stream THEN there would be more animals living in the stream. This is also a testable hypothesis in which I can observe and record the amount of pollution in the stream and specify what kind of waste and debris there are. Then, I record the number of animals living in the stream. Then, clean out some of the pollution in the stream or the main sources of debris and observe and record the number of animals living in the stream. Lastly, another testable hypothesis I can create is IF the water in the Manoa Stream always looks brown, murky, and polluted THEN the water readings (such as pH level, Dissolved Oxygen (DO), turbidity, odor) of the Manoa Stream will be contaminated. This is a testable hypothesis in which I take a cup of water from the upstream of the Manoa Stream and a cup of water from the downstream. I calculate both of the cups of waters’ pH level, turbidity, odor, and amount of Dissolved oxygen (DO) with the DO probe, pH probe, and etc. The results of these readings will show how acidic or clear the water in the Manoa stream is. Out of the three hypotheses, the water readings is the most problematic because I will need to use or buy a DO probe, pH probe, or a water reading kit to do my experiment. The dirty and contaminated water that might contain bacterial diseases or leptospirosis might also be a hazardous concern.

The tree was knocked down to the ground by the heavy winds.

The plants were blown in one direction by the heavy winds.
