Microscope+Test

**Hypothesis:** We think that the river water that we took the sample from will have many different organisms that will affect the heath of the water. If there are organisms in the water that we took a sample from, and these organisms are unhealthy, then the health of the water will not be healthy.
 * Period 6 Group D Kelly Brett Julia **
 * Prediction:**

1. Take a sample of water from the river with other living organisms in it that are from the same river. 2. Put one drop of water on the slide. Put a slide cover over it. 3. Put the slide with the drop of water on it on the microscope stage. 4. Look at it through the Microscope and look for any organisms. 5. Identify and record your observations. Under High Power we could not see anything on the slide Under Low power we could see many different black and blue dots but could not get close enough and focus to identify the organisms. In conclusion we could not focus the microscope enough to identify the organisms. Under low power we could see that there is some kind of organisms in the river but under high power we could not see anything. So we do not know what the organisms are that we found in the water sample. **Period - 6 Group F: Matt, Laura, and Juliette
 * Procedure:**
 * Observations: **
 * Conclusion**

Hypothesis:** We believe that there will be various organisms that will be affecting the water well being. If we take a small sample of the water and look for organisms, and we find various types of organisms/ bacteria, then we believe that the water will be unhealthy.
 * Prediction:**

1. Take a small sample of water from the river. 2. Put one drop of water on the slide with a pippette. Place a slide cover over the slide. 3. Put the slide on the stage of the microscope and observe the slide on low power. Observe the slide in five different positions. 4. Do the same for the slide under the high power view. 5. Record/ draw the different things you see under each view. 6. Identify the organisms that you observe.
 * Procedure:**

High Power:** First view- We do not see any organisms. There are black dots in the bottom left corner. Second View- We saw a few airbubbles. Third view- We saw the same thing that we did in the first view. Fourth view- We saw the same view. Something that may have been some sort of organism flowed through. Fifth view- It was the same as the previous with a few bubbles. First view- We saw a lot of bubbles, with a few black dots. Second view- It was the same as previous. Third view- We may have seen an organism, but it did look like it. Fourth view- It had a few black dots and air bubbles. Fifth view- It was the same as the first view.
 * Observations:
 * Low power:**

After conducting our experiment we learned that the water sample we had little to no organisms in it. Our prediction/ hypothesis was incorrect because we said that we would find many organisms, but we didn't. We think this may have been because our water sample was near a point source so organisms may not like the pollution from it. In conclusion, we believe that the river is healthy based on what we observed in this test. We did noit find any unhealthy organisms that would affect the water in a bad way.
 * Conclusion:**

**Period 6- Group B:** **Natalie, Nicole, Jacob**

We think that there is going to be a lot of organisms which will negativly affect the heath of the water. So we should find non living particles and organisms in the water. When we investigate / research what organisms we found, it should say that they are bad for the river's heath.
 * Hypothesis:**

**<** This is a picture of the water in a slide on the microscope.

If there are organisms that negativly affect the water and we examine the water under a microscope and research what we find then we expect the research to show that these organisms are bad for the river.
 * Prediction:**

1. Get river water. 2. Put about 1 drop on the slide using a pippette. 3. Place cover slip on water sample. 4. Put on the stage of the microscope. 5. Look at slide in five different locations. 6. Draw what is seen on high/low power.
 * Procedure:**


 * Conclusion:** We did find harmful bacteria and particles in the water. Some of the bacteria in the water was moving and looked like it was a really small bug. When we were looking under the microscope some things were moving or nothing was happened. There were some big particles in the water, and some didn't move at all. This proves that the water is unhealthy.

Group F- Period 3, Lke, Chris, Stacy, Isabella Purpose-We wanted to find out what kind of organisms that live in the river. We also will look for the answer, if the river is healthy or unhealthy.

Hypothesis- We believe that there will be few fish but a lot of microorganisms like paramecia and euglena. There will be no harmful organisms, so the river will be healthy.

Prediction: If there will be some fish and a lot of microorganisms in the healthy river, and we observe samples of the water under a microscope, then we should see more microorganisms than fish, including detrtus.

Procedure: 1) Take a water sample from the river and record where you took it. 2) Put a drop of water onto a slide and cover with a cover sheet. 3) Put a slide under the microscope and turn on the microscope.   4) Adjust the microscope so it is clear and you can see something. 5) Look for organisms in the water and when you find one, draw what it looks like.   6) Record what kind of organism it was and how many were in the water. ** Data- ** The organisms came in different sizes and were eating the algae and detritus. They moved around a lot and we observed cilia. There was a lot of dirt mixed in the algae and that created a food source for the organisms. We saw at least four or five distinct organisms on the slide. Paramecia was also found ** Conclusion- ** Our conclusion is that life is very much a part of the water from the Passaic River. We also saw algae in the water. This provided the food source for many of the living organisms. There were many microorganisms like paramecia swimming around in the water. We did not find any microoganisms that indicate an unhealthy river system. So we conclude that our hypothesis was supported.

Period 3 Group B Josh L, Adriel, Johnny, Julia O Hypothesis: We believe that the slides we make will contain organisms. There will be dirt and algae, because we think the river is unhealthy.

Prediction: If organisms and bacteria are present in the slide and we search for them then, the water will be dirty.

Materials: -Microscope -Slide -Cover slip -Water sample -Pencil -Notebook -Eyedropper

Procedure: 1) Take a bin of water from the river 2) Take the eyedropper and suck in water 3) Squeeze a sample on a slide 4) Place a cover slip over slide 5) Put slide on microscope and lock 6) Focus out and then back in to slide 7) Look around for unusual objects 8) Record data 10) Repeat steps 2-8, but take sample in a different place of the river

Observations: The first thing I found was paramecium there were small ones and big ones. We also found detritus. We also found air bubbles, but it does not matter because the cover slip will case this. The paramecium looked like it was eating, probably algae. Other organisms were just moving or swimming. Conclusion: We found harmful and hurting organisms and materials, our hypothesis is supported that the river is unhealthy.


 * Period 3, Group C Steven, Billy, Lily, Eva

Hypothesis:** Our hypothesis is that we will find some organisms in the water samples. We expect to find organisms that will live in this water and eat some of the plant matter in the water.


 * Prediction:** Our prediction is that if we collect water and observe it under a microscope then we will find organisms and plant matter.


 * Materials:** notebook, pencil, slide, coverslip, light microscope, water sample

1. Collect water from the river and bring it back to the classroom 2. Take a pipette an put a small drop of the sample on to a slide 3. Place a cover slip on the slide and put it on the microscope stage 4. Turn on the microscope, look through the eyepiece, and focus the image on low power 5. When you find something interesting, switch the objective lens to high power and refocus the image.
 * Procedure:**


 * Observations:** Under the microscope we observed many things in the water. The first of these was detris, which was floating in the water. The second was a few single-cell organisms. These were just swimming around in the water. Finally when we observed some algae, it appeared to be broken into many sections. There were also some other single-cell organisms, that we think are paramecium, eating the algae.


 * Conclusion:** Our hypothesis was supported. We found some organisms that match the description for paramecium swimming around. Although, we did not find as many organisms as we had hoped for. Our hypothesis was also supported because there was also some organisms eating the plant matter.
