Temperature+Test


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


 * Hypothesis:** We think that the temp will chnage in different parts of the river and when its sunny the water will be warmer in that area, and where there is shade, the water will be cooler.


 * Prediction:** If the sun affects the temperature and we take the temperature of the sun and shade. The spots in the sun should ne greater than the shade.

1. Get thermometer 2. Place thermometer in different spots of the river. 3. Write down where the location is and the temperature. 4. Compare temperatures to different locations of the river.
 * Procedure:**


 * Temperatures:**
 * **Location** || **Temperature** || **Sun/Shade** ||
 * Behind the bridge || 45.8°F || shade ||
 * By big tree || 47.4°F || shade ||
 * Point sourse by tree || 54.1°F || sun ||
 * Big black tunnel || 52.3°F || sun ||
 * White house || 47.4°F || shade ||
 * Crossing pipe by central || 48.9°F || sun ||


 * Conclusion:** Our conclusion is that the water in the sun is warmer than the water in the shade. Also water under the something such as newspaper, leaves and rocks are in the middle of the temperatures. Point sources are warmer than the water in the river. Different locations in the water that are all in shade still have different results of temperature. One day you could see what the temperature is in the same spot as the day before, and they could still manage to have a different temperature.

= Period 3, Group C-  Lily, Eva, Steven, and Billy=


 * Purpose:** To see how hot or cold the water is, and how it affects the animals living in it.


 * Hypothesis:** We expect that the river will be relatively cold because we are in the winter months. We also expect it to be cooler in the shade than in the sun. We also expect deeper water to be colder.

**Prediction:** If sun and depth affect water temperature, and we place a thermometer in the water to check the temperature in different areas, then we should find that the temperatures in the sunnier and shallower areas are higher.

**Materials:** ** Procedure: ** > > **Observations:** Before we checked the temperature of the water, we knew it was cold by the way it felt when we placed the thermometer in the water. We checked the temperature in different places such as shady and sunny areas. We noticed that the temperature was higher in the sunny areas but one. It was warmer under the bridge than in a sunny area, which we thought was weird. > || Under bridge (shade) || 43.3°F || > || Random spot that’s sunny || 42.9 °F || > || Middle of stream || 45.3 °F || > || Coming out of point source || 45.3 °F || > || Middle of stream in a different spot that is sunny || 42.2 °F || > || Ripples/ deep water || 42.4 °F || > **Conclusion:** The conclusion we came up with in our experiment was that the temperature changes in certain areas. We found that in shady areas the temperature was colder except under the bridge. The sunny areas are warmer. Our hypothesis was proved and disproved. It was proved because it was colder in shady places. It was disproved because only in one place we checked it was warmer than in the sunnier place. We had no proof to see that a small change in temperature could affect plant or animal life. Some future research we could is to come back and take the temperature of the same spots in the summer and compare the results. > > > > Period 3, Group D: Kaitlyn, Joe, Jamie, Casey > > Materials: Digital thermometer > > Purpose: To test the temperature of the river. This will help determine if the river is healthy or not. If it is high then there will be less oxygen and less plant life making it unhealthy. If the temperature is low then there is more of a chance it could support plant and animal life making it more healthy. > > Hypothesis: We think that the river is not healthy so we think that the temperature of the river is going to be high and we think when the water is moving fast, the temperature will be warmer. This would mean that there is less oxygen and it would not support fish and plant life. > > Prediction: If the river is unhealthy and the speed of the river affects the temperature and we put a thermometer in the water in 5 locations then in the areas where the speed is fast should have a high temperature. > > Procedure: > 1. Take five different temperatures at different places in the river where there is a change in the speed of the current > 2. Walk underneath the bridge where water is moving fast to take the temperature. > 3. Stick the thermometer an inch deep in the water, wait about ten seconds and record the temperature. > 4. Repeat step number 3 in four other locations: coming out of the black tunnel, in a ripple zone where the water’s moving really fast, in the bubbles where the water isn’t moving, and past the bridge where the water is moving slowly. > > > Location Temperature > || Past the bridge to the left where the water is moving slow. || 46 °F || > || Coming out of a point source - black tunnel where the water is moving really slow. || 51 °F || > || In a puddle of bubbles where the water is not moving || 45.6 °F || > || In a ripple zone where the water is moving really fast. || 42 °F || Observations: The temperature was higher wherer there was a point source compared to anywhere else in the river. When the water wasn't moving or moving slow, the temperature was higher than when the water was moving fast. > > Conclusions: We had thought that the temperature would be high in an area where the water was moving fast. This was disproven because the temperatures were lower and colder where it was moving fast. We also thought that the water would be unhealthy. This was disproven. We did research to find that the Amazon river ranges from 58 degrees to 77 degrees and it is healthy becasue it supports a variety of life (which means that temperatures like those are considered healthy). Based on the temperatures the river is healthy. > > > Period 6, Group C: Jocelyn, Stephanie, and Alex > Materials: Digital thermometer > > Purpose: To find out what the temerature of the river is, and to see if the water near the point sources is warmer or colder. We also wanted to find out if the temperature changes when the water gets deeper. We also wanted to see if the colder areas could support more plant and animal life. > > Hypothesis: We belive that the temperature near the point soures should be warmer than the water outside the point source because pollution is coming into the river which would support our idea that the river is unhealthy. Additionaly, **warmer water will hold less oxygen** which also shows that the **river is unhealthy because no oxygen means no life.** > > Prediction: If water is **warmer near point sources inidcating pollution**, and take the temerature near point sources and upstream from point sources, then the water near the point sources should be significantly warmer ( greater than 5 degrees) than further upstream. > > Procedure Summary: > 1. Our first temperture we took was by the walking bridge and it was 41.9 degrees F. > 2. The second temperature we took was in between the two bridges and it was 47.8 degrees F. > 3. The third temerature we took was in between the bridge and a piont source and it was 46.9 degrees F. > 4. The last temperature we took was near the black point source and it was 52.8 degrees F. > > Conclusion: When we took the temperatures it showed that the water near the point sources were warmer than the water further upstream. The water near the point source was 11 degrees warmer than the water by the bridge. (that was upstream from the point source) > > > ** PERIOD 3, GROUP F- Luke, Stacy, Chris, Isabella ** > ** Purpose: ** Our goal is to find out how temperature affects the organisms and the wellness of the river, as well as if the temperature affects things around the river. >  ** Hypothesis: ** if the water is warmer than it will support more bacteria life, but when it is cooler it can support more organisms and fewer bacteria. The warmer water supports more bacteria because they can live easier and reproduce faster in hotter climates. >  ** Prediction: ** If bigger organisms are found in cooler temps and we get a sample of cooler water then there should be a lot of larger organisms. On the other hand, if we get hotter water and look at it under a microscope then we should she more organisms but they should be smaller. >  ** Procedure: ** 1. walk down you part of the river and take temps at various landmarks and intervals. > 2. Write temps down in your notebook and into a data table. > 3. Observe life and water in the places where you took the temps; with naked eye and through a microscope. >  > ||  By the tree  ||  41.5  || > || Near first point source  ||  41.7  || > || Near second point source (in the sun)  ||  41.7  || > || Gully in the river  ||  42  || > || Non point source  ||  42  || > || Under the bridge  ||  42  || > || In the tunnel  ||  52  || > || Right after tunnel/ in the middle of the river  ||  51  || > || Ten yards down  ||  42  || > || Fifty yards from last point source  ||  42  || > || Last non point source; seventy yards  ||  42  || > || In the tunnel  ||  44.7  || > Conclusion: as we walked along the river taking the different temps we saw a small variation in the temp; the exception is in the big black point source. The average was from 41 to 44 but in the river as you can see was about ten degrees higher. our hypothesis, in hotter water more bacteria and less oranisms survive; on the other hand, cool water supports more organisms and less bacteria. That hypothesis was supported by two things. One is that right in front of the black piont source the water was 51 and there was no life that we saw with a naked eye; but underr a microscope we found many micro organisms like paramecia. But in the areas where the water was around 42 we saw water striders and around ten fish in total. That data supports our hypothesis, and we keep our hypothesis the way it is stated. > > > **Period 6, Group D:** > > __Hypothesis:__ We believe that in deeper sections of the river, the water temperature will be cooler then in shallower parts. Also, if the section of the river that we test is in the sun, it will be warmer then in the shady parts. > __Prediction:__ If we test sections of the river in the sun and shade, and in deep and shallow water, and we hold the thermometer in that water for 44 seconds, then our outcome should support our hypothesis. > __Procedure:__ >
