** PROJECT 1 Nakamura Lock Airplane Tests **

Below is an example of one of a lab conclusion and graph.

 __Nakumaru Lock Conclusion__ __Elliot M September, 24 6C__  If you add a paperclip the plane it will go faster.My control plane had an average of 4.97 m and my experimental (paper clip) has an average of 10.5 m. The experimental went further because the weight of the paper clip would of pulled it down faster and the lift would of made it go higher so it would go fast because of the weight and go farther because the lift is preventing it from landing. The thrust of when you throw it plus the paper clip will also make it go faster.The extra weight worked well. If I were to do the experiment again I would keep the paperclip on and also make the wings a bit bigger.The only problem is that each time I throw it the angle and power of the throw will be a little different every time and that will make a difference and also the wind is always blowing in different different directions. .  ** ﻿ **

** PROJECT 2 Hawk Mountain Data Project **

Below is an example of two graphs and conclusion a student shared with me on Google docs. I was able to comment and make suggestions.

Cameron H 6-D Hawk Graph Project Science

 The graph right above this paragraph is on the migration of a Sharp-Shinned hawk and a broad winged hawk seen on the lookouts of Hawk Mountain. In the graph the broad winged hawk is more of a late September bird than in a early October. A Sharp Shinned hawk is seen equally throughout both months. I think my graph is relevant to the other graphs I have seen. We did not see any sharp Shinned nor Broad winged hawks during the field trip. We saw a lots of birds such as an osprey, and black vulture. The hike showed me that hawks come to Hawk Mountain because of the many updrafts and thermals .

 My second graph is the migration of a Osprey and a Black Vulture. The Osprey is mostly seen during early October than it is seen during late September. The Black Vulture isn’t really seen during both months but is seen mostly during late September. This graph sort of agrees with the other graphs I saw. The graph tells me that Ospreys are a early October bird and that black vultures aren’t really seen during the two months.This graph relates a little to are hike because we did see a lot of Ospreys. The birds we saw were ospreys, and black vultures. The hike showed me that hawks come to Hawk Mountain because of the thermals an updrafts.

It has good soil and a very nice temperature. I really like how there is good water drainage and great sun. It has a total of 27 points. The learning garden would come in second because it is in an enclosed courtyard, and it is not safe from predators. The good things about it are that it has a fairly good drainage system, and has good exposure to the sun. It has a total of 24 points. The middle school garden is last because there could be too much shade and it is not safe from foot traffic and chemicals like food and plastic wrappers because people are allowed to eat out on the tables next to the garden. It has a total of 18 points.

<span style="color: #000080; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; margin: 0px; padding: 0px;">Our first experiment for our study of chemistry, the students watched the change of state from solid, liquid, to gas using a hot plate. The students made a scatter line graph and wrote a conclusion on google docs. Here is an example of a few of the projects.

GARRETT B 6A Feb 2011 <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"> <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The lab we did in science was very eye-opening to me. I know how to boil water and stuff, but doing this lab was really, “dissecting” it getting a much closer look at what is really going on and how it happens, two things I would not otherwise know about. This lab was obviously cyclic causality because if the state-changing aspect to it. The water goes from solid ,to liquid and to gas then may become solid again. Referring to my graph, there are 2 flat parts of the temperature. These are occurring because at the beginning because the burner is still heating up and the ice is taking time to melt. this would appear at the end because there is no more room to heat up the water, because it is already at the highest possible temperature in the given circumstances. When the molecules begin to heat up, they move faster and separate into a gas. People may have taken longer times to heat up because the amount of ice put in was not kept consistent and it may have taken longer to melt the ice than others. <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"><span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"><span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; margin: 0px; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Parker H February, 22, 2011 COS Lab Conclusion <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; margin: 0px; white-space: normal;"> <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"> I think that this was a great project for us students because we got to watch the process of a solid changing to a liquid to a gas. The experiment was cyclic causality because the water that evaporated rains back down to the earth, and we can use the water again. Our scatter graph had two plateaus at the top and bottom because the heat did not get much hotter because it was just warming up and just at it boiling point. When I was watching, I saw that the ice cubes melt into the water and then turn to gas, because when the ice is being heated, then the molecules loosen to the point where they are in a different state. Different people had different boiling times because they might not have put the thermometer in at the correct time, or made the temperature to hot on the burner. I wouldn’t change the experiment but I learned and saw the change of state from a solid to a liquid to a gas. I was also great for us because we got to use a burner! What kid doesn’t want to boil water over a 375 degree burner in science class! That's great! Anyway, I felt that I had a positive outcome from this experiment and that I definitely learned something from it. I loved the project and I thought it was really fun. <span style="background-color: transparent; color: #6fa8dc; font-family: Arial; font-size: 11pt; font-style: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">**One reason the water might have taken different times is the different volumes each group had. I made sure to have your volume relatively low, since you were doing the experiment in one class period. In the longer class period, we had more water. More water means more molecules to move, so it’s longer to get to boiling.****Mr. D**

<span style="color: #000080; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 13px; line-height: 19px; margin: 0px; padding: 0px;">Students asked the question, "What ratio of vinegar and baking soda will have the biggest reaction?" and tested this in the lab.

<span style="color: #ff5e00; font-family: arial,helvetica,sans-serif; font-size: 14px; line-height: 21px; margin: 0px; padding: 0px;">Below is an example of one of a lab conclusion and graph.

It is domino because after a series of tasks, it does not end up the way that it was. If it was cyclic, it would have to end up with the same thing that we started with. That was not the case. I was very surprised to see how close our groups data was to the class. This shows that our group, Jack B, Jack M, Freddie H and Aaron H, collected the data well and accurately. The reason that I think that our data is so accurate, is the fact that not 1 number that we had was 1 off from the whole class average. Each step we went through carefully and slowly. This turned out to be a great idea because we got great data. Even though we were the last group to finish, I believe that it was worth it. Overall, the ultimate fizz lab really helped me in science. Both our group and the class found the 10 mL of baking soda to react the most with 30 mL of vinegar. This was a perfect 1:3 ratio. More baking soda does not necessarily mean a greater reaction.

Watching the chemical reaction was even more of an eye opener than the ultimate fizz lab. It showed me the different kinds of reactions that you can make. For me, I found it amazing that simple things like just bringing them together, like the Magnesium + Oxygen experiment, could create something so cool. In summary, I really enjoyed the demonstrations in the upper school.

** PROJECT 11 Spring Garden Measurements - Tulip Plants - April 2011 **

<span style="color: #000080; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; margin: 0px; padding: 0px;">The students collected data from each garden to find out which tulips were growing best. The students understould the different variables such as soil quality, sunlight, temperature, and water all played a role in the different results. Once the results were analyzed, the students made decisions on how to amend the soil and care for the garden in the spring.

How do your predictions from the FALL 2010 compare to the results of early April 2011? <span style="background-color: transparent; color: #ff0000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">I think that my predictions were well hypothesized. My number one made it to first but my number two came in last, and my number three came in second. Overall, I think that I did a good job predicting. <span style="background-color: transparent; color: #000000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; margin-bottom: 0pt; margin-top: 0pt; text-decoration: none; text-indent: 36pt; vertical-align: baseline; white-space: pre-wrap;">2. What variables seem to be playing a role in the results? <span style="background-color: transparent; color: #ff0000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The variables that seem to be playing a role are the location of the garden and the type of soil. Plants that grow in gardens that get lots of sunlight should grow more than plants that don’t get sunlight. Plants that grow in soil that has lots of nutrients should grow more too. <span style="background-color: transparent; color: #000000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; margin-bottom: 0pt; margin-top: 0pt; text-decoration: none; text-indent: 36pt; vertical-align: baseline; white-space: pre-wrap;">3. What new questions do you have about the health of each garden? <span style="background-color: transparent; color: #ff0000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The question I have is how is the soil? We found that gardens that face the same direction didn’t have the same amount of plant growth. That means something else must have affected the growth and I wonder if it was the nutrients in the soil. <span style="background-color: transparent; color: #000000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; margin-bottom: 0pt; margin-top: 0pt; text-decoration: none; text-indent: 36pt; vertical-align: baseline; white-space: pre-wrap;">4. How do you think we can improve the gardens? <span style="background-color: transparent; color: #ff0000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">One way to improve the gardens would be to make sure they are placed in a place where there is lots of sun. But since you can’t move the garden you can help the soil become more nutritious. One thing I have heard about is using compost in the soil. That is supposed to really help plants grow. <span style="background-color: transparent; color: #000000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; margin-bottom: 0pt; margin-top: 0pt; text-decoration: none; text-indent: 36pt; vertical-align: baseline; white-space: pre-wrap;">5. Which gardens have plants that are already blooming – you can see the flowers? Which gardens do you think will flower first based on your observations in the school gardens? <span style="background-color: transparent; color: #ff0000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The Suter garden with western exposure has the flowers that are already blooming. I think that the gardens that will flower first are the ones that have the best plant growth. That would be Crossman Hall NE exposure and Lower School pick-up line. <span style="background-color: transparent; color: #000000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">6. what other signs of spring have you seen around school, home, or anywhere around you? <span style="background-color: transparent; color: #ff0000; font-family: Verdana; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Other signs of spring I have seen around school and home include the flowers coming up all around my house and my mom cutting the flowers and bringing them into the house. Spring is when my dad tries to go trout fishing and the best sign of spring at Haverford is that fact that it is lacrosse season. <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"><span style="font-family: arial,helvetica,sans-serif; font-size: 13px; line-height: 19px;">** PROJECT 11 Osmosis Egg Lab ** <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;"> This lab involved an egg changing shape on which liquid it was sitting in because of osmosis. Osmosis is the diffusion of water through the membrane from high to low concentration. This lab involves osmosis because the amount of water the egg was in, the larger the egg was. This is because the membrane took water in which made it get big. When water was surrounding it, it was at its largest. When vinegar was in the beaker, it was second largest because vinegar has over 80% water in it, it grew a little, but not as much as water. But when corn syrup was surrounding the egg, it shrunk to the point it was like a popped balloon with a yolk inside of it. This was because the amount of water in the corn syrup is not 80%, but lower. As you can see, the osmosis lab is a very cool lab that really shows osmosis. <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> <span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium; line-height: normal;"> =<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 24pt; font-style: normal; margin-bottom: 0pt; margin-top: 0pt; text-align: center; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">**Osmosis Lab Report** =

In this lab, osmosis is shown by putting in egg in water, and watching the water leak into the egg and expand it with osmosis. Then we put in syrup and watch the water come out of the egg and into the syrup with osmosis. Osmosis is important to plants and many other living things because without osmosis, water would not be able to travel up the stem to the important parts of the plant. For example, osmosis is important to our baby bean plant because the water needs to get up to the top so the plant can grow more and eventually produce more beans. In my opinion, this lab is cyclic because if we were to put more water in the beaker and take out the syrup, the egg would grow to it’s normal size again. In the end, we learned a lot about how plants get water from their roots to the top of the plants in this lab.
