Inquiry set up. When we where starting the Duck weed proses we added 20ml of water. Then we added a small pinch of fronds. After that we wrote the numbers of fronds on the bottle so we know how many fronds we have in each of the bottles. After we aded the fronds we then added one ml of liquid fertilizer. Then we put the test tubes on the rack so they cold get some sun but before we put them on the rack we put the number order that the bottles where in on a peas of pepper so we know which group the rack goes to.
Phosphors set up. Phosphorus is a cemicle that is bad for the water. With all the farms around the water is not heathy. The stuff that the farmers use is called fertilizer. Fertilizer is killing fish and some plans. Each farm can hold 1,00 chemicals. If the river has too many chemicals in it the chemicals will kill all the plants and animals in the lake or river. Fertilizer concentration can affect the growth of duck weed. To much bacteria can kill plants and animals because there is not enough oxygen.

My class and Mrs.Pierpont’s classes came together and tested 3 different samples of water. One was from our guppy tank and the other was from Monkton pond a week ago. The third one was from Monkton pond yesterday. We took some notes from 3 different categories: Raw Data, Evidence, and Reason. For raw data I compared sample A and sample B. Sample A is sort of foggy. When we added sulfate to sample A, both A and B looked like rust. Both A and B is starting to chunk up. We added oxygen to sample A. For evidence there were chemicals in sample A and sample B. My claim is that all 3 samples are going to show different results. My reasoning for my claim is because the guppy water is cleaner than the pond water and even though there are 2 Monkton pond samples one is more different than the other because one has been out of Monkton pond longer than the other.

In science my class and l have been studying the water uses of Monkton pond and trying to see what is making the water so polluted. We made our own models.Before we made are models we made a predictions and filled out some questions.then we made a good model and a bad model. After we made the good and bad model we ran them. When we ran the examples we had to watch what happened to the water. We put blue food coloring in the water so we can see if the water changed color or if it got dirtier. I noticed that for the bad model the water got stuck in between the rocks and trash and it picked up the trash and dirt. For the good model it picked up only the dirt because it was not polluted like the bad model was. And after we ran our models we answered more questions. I hope you enjoy!
