Here is my what is science paper: What is Science? Science is what scientists observe or have a hypothesis about something. For example, one scientist could observe something and could be corrected by a different scientist. The scientist that could correct a different scientist would mean that he is helping him in a way.

In the real world of scientists..... are problem solvers that find new ways to help us. Scientists could help one another at trying to do something. If one scientist was trying to figure something out, he might need some help from another scientist.

In science class we..... experiment and do things such as labs to solve what we are learning about. Things such as this help you do science in a more fun way instead of reading through the textbook which could be very necessary.

The purpose of this site is..... to show others and teaches others which means that they will learn by doing this. Its very important that not only one of us knows what to do but for everyone to also.

Here is the link to my PowerPoint:

History of measurement paragraph: History of measurement was a very important part of our history. The ancient Egyptians developed the first known weighing instrument, a simple balance with a pointer. They used body parts to measure things like the elbow and the tip of the middle finger. Although scientists rely on SI units, people use other measurement units also. In 1714 A.D, Gabriel Fahrenheit invented the thermometer.The history of measurement carries on today and will be in the future.

Reflection on the Changes in State and Viscosity Lab (What I Learned....] In class today, we were working on a lab that was extremely fun all about viscosity. Viscosity is the amount of resistence on an object.The lab was full of excitement and was very interesting. The picture below is a picture of the lab we did. This lab helped me understand that temperature is very important and many other very entertaining things. I learned that when the temperature is bigger, the longer it takes for the marble to reach the bottom. The lab that i did today helped me because i am a visual learner and that helped me lots in this lab.

 * Reflection **
 * We did a lab today that was something that you needed to have patience for the technical difficulties. Sometimes you have a lot, and sometimes you don't. You just have to have patience with it. Our lab today was based on having patience because you needed to pump the the pump which would soon fill the tube and eventually explode. The one thing I learned today mostly is that when you add more things in a tube, the pressure will increase highly because they don't have anywhere to go. **

__**Introduction**__: Today, we did a lab on melting ice. The lab was very fun and we learned many things. What we did was timed how long it took for the ice to melt. The objective of the lab was to see how long it took. Above this is a data table full of the information and data. We watched and watched as the ice melted into the water. __**purpose:**__ The purpose of the lab was to see how fast the ice melted into the water. Another purpose of the lab was to time the rate at which the ice melted in your groups. <span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">**__Hypothesis:__** My hypothesis was that the higher the temperature was, the faster the ice will melt. <span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">**__Materials:__**The materials that were needed were a thermometer, a stopwatch, ice cubes, two glass cups, and water. <span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">**__Procedure__**: Above is a graph that shows the data. <span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">**__Data and observations:__** I observed many interesting things like how the ice dissolved into the water. Another thing that I learned doing this lab. I also learned that when the water temperature increases, the ice will dissolve quicker. <span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">**__Results:__** There were many things that happened in this experiment. We had four trials to do during this lab. In the beginning of this experiment we were to put room water in a cup and see how hot it was. We then were supposed to record our data. The next thing was that we had to do it again but this time we did it with room temperature water which is a little warmer than the other water. What was interesting was that the ice melted faster when it was warmer water. What we were measuring was the time it took to have the ice melt. <span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">**__Conclusions:__** I have learned many interesting things from this project.The hypothesis I had was that the warmer the water was, the fater the ice would take to melt. I found out that my hypothesis was correct after all because when the water was warmer the ice would melt faster. According to the data table above, it was true that when the water was warmer, the ice melt faster. __**<span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">Discussion: **__<span style="color: #800000; font-family: Impact,Charcoal,sans-serif; font-size: 140%;">Although this was a very fun lab, we had some difficulties as a group as well. For example, we stopped the thermometer not knowing that it was going to keep going and so we would have to restart. Another thing that was an error was that we forgot to set the timer. Something you may have to consider is that the probe may have had some technical difficulties or something like that.



__Reflection On Bohr Model:__

Today, we did a challenging lab on building atoms. I say challenging because it took me a while to get started with it and understanding it. I learned many things while I was doing this lab though. the most interesting thing that I learned had to be that there can only be two electrons on the line closest to the nucleus.Along with many fun and interesting things I learned, I had some troubles too. The most important thing that I struggled with was starting the lab because I didn't get the steps we were to do in order to succeed. I enjoyed doing that lab after all and would do it again someday.

__**Alka Seltzer Lab:**__ The purpose of this lab was to find out how temperature effects the speed of a chemical reaction. The evidence that the chemical reaction is taking place is that the color changes, bubbling, and the smell changes. We predicted as a group that the rate of reaction would be 3 times faster than at 0 degrees celcius. 3 trials were done by us in this project. In the the first trial we observed that the time was 69 seconds and the temperature was at 15.7 degrees celcius. The second trial took us 18 seconds and the final temperature was 83.1 degrees celcius. The final trial that we did took 204 seconds and ended up at 0.2 degrees celcius. The evidence I saw in each trial was that it took longer and sometimes it took a less amount of time. As the temperature increases, the rate of reaction increases. On the evidence I have, the other solutions will occur that the hotter the water, the faster it will melt. It was evident that the purpose of the lab was met because we got the data that we needed to have.



** Experiment **** 1 **

In this experiment the chemicals that were used were Enothermic reaction and Ammunion Nitrite. The variables that were used that controlled the rate were water temperature. You can tell a chemical reaction took place by the temperature changing from 60 degrees F to 35 degrees F. This experiment would take place in everyday life because reactions happen everywhere and this is one. I would love to try this experiment out because I love experiments and the outcome is always different and amazing. This video added to my knowledge because I didn’t know about all the variables and other stuff about the Enothermic reaction and Ammunion Nitrite.

Propane summery

In class today, we got our element for our popplet! I was really excited to find out what my element was and when I found out it was propane, I could not wait to get the information about it. I was so excited that I started early. What we were supposed to do with our element is find the atomic structure, figure out what bond it forms, examples, and the history behind it. We are also to create a model based on the atomic structure of the atom we were selected for. It was really fun to do this mini project and I know LOTS about propane now that I learned about it.



Summery of chemical bonding activity In class today, we worked on an activity of chemical bonding. As you see the picture above, that is what we basically were learning about. I really enjoyed doing this project because it helped me with a visual about chemical bonding. I believe that I am a visual learner more than listening. I wouldn't mind to do this project again but I would like to use a different element. I enjoyed and would love to do this again!



Reflection In class today, we worked on a web tool called fotoabble. We had to add a voice to make it more entertaining and fun! We then uploaded a photo from snapfish and uploaded it. The purpose of this was for the reader to understand more about Newton's law. The law that we learned about was the third one. I also worked with a friend to be successful. We were successful because we added our voice and picture greatly. media type="custom" key="16182114"

Reflection In class today, we learned about how to use Scratch. Sratch is a great tool to use to learn about someone or to learn about something. Scratch is a digital tool that many other people use to be successful. With Scratch, you can do things such as make and animate characters. Other things that are great for scratch are you can make games and things like that. I would love to create a game off of scratch because it would be lots of FUN!

Reflection Today in class, we learned how to use a very interesting tool. This tool is dipity. Dipity had a little trouble for us as we ran into trouble. It wouldn't load fastly and so we needed to find a solution. Some people moved on to a different tool but I decided to stay on Dipity.

Reflection In class today, we learned about how to use a tool called Bio Cube. We had to learn about a certain scientist to learn about so I chose to learn about Galileo. Galileo was a very interesting scientist to learn about becaus he had a secretary that would read him his work because he was blind. He is very important to learn about because he improved the telescope lots. Galileo was a scientist that was into science, stubborn, curious, brialliant, and loving. I am glad to be able to learn about such a brilliant scientist and would love to learn even more about him.
