Purpose: The purpose of this experiment is to see what will happen when you add Isopropyl Alcohol and a solution of soap, tap water and sodium bicarbonate to a syringe with small discs of spinach. The control being without Isopropyl Alcohol and just the solution and spinach discs.
Hypothesis: If you add Isopropyl Alcohol to a solution of soap, tap water and sodium bicarbonate with small discs of spinach in a syringe then the spinach will disintegrate because the alcohol will breakdown the leaf itself and destroy it.
Procedure: We will place 10 small hole punch sized discs of spinach in a syringe and add isopropyl alcohol and a solution of soap, sodium bicarbonate and water. Take out all of the CO2 and Oxygen and place it under a light.
Data: The spinach with the isopropyl alcohol had 8/10 spinach discs float back up to the top after removing the gases from the syringe and only 4/10 of the discs in the control, consisting of soap, water and sodium bicarbonate floated back up in 15 minutes.
Conclusion: We found that the alcohol actually helped the spinach float and was more successful then the control group with the solution itself. The syringe with the solution and the alcohol had 8/10 spinach discs float and the syringe with just the solution only had 4/10 discs float. Our hypothesis was way off. We thought that the spinach discs were going to disintegrate because the alcohol would break down the spinach cells and destroy it. Nothing of the sort happened. The spinach was in the same shape and unaffected by the alcohol. We made the control syringe before the experiment syringe and put the control under the light before the experiment one. This gave the control a little more time to produce the gases but didn't seem to make an impact on the results, to our knowledge.

Our last competition for the mouse trap bolt was a complete failure. The objective was to make the car go and stop in a designated area and launch a ping pong ball into a bucket across the room. So we tried to modify our car so that it would brake in the area but when we tried to add brakes the car wouldn't move off the starting line. We tried to cut the line that connected to the arm and the axel. By making that string shorter the car wouldn't go as far. So we were stuck on how to complete this task. We couldn't come up with anything so we added tape to the wheels so it wouldn't spin out at the beginning. That worked! But we couldn't get the catapult to work. So we tried to attach the catapult to the front axel instead of the back one. That also didn't work. We tried out many designs. We made a triple decker, a double decker, and a single decker. None of those worked. So we were stuck with something that didn't work. Overall I had a blast doing this bolt and if there was another bolt like this I would do it again!

Last week we did a lab in the science room. We went over how seeds grow into plants. First you plant the seed. Eventually the seed will grow roots. Once the roots hold on to something they break through the soil. That means the seed has sprouted also known as germination. The seed/plants grows from nutrients that it gets from the soil. Three things plants need to grow are food, light, and water. The sun helps start photosynthesis. After that is completed the plant is ready! Our process started with putting this liquid in the bottom of the jar then adding non leak tissue so the liquid wouldn't touch what was on top which was the peas. We stuck a tube onto the jar and added food coloring to the top so we could watch the water get sucked into the pea jar. Our conclusion was that peas were not affected by anything.

The objective was to launch a ping pong ball 3 meters into a folgers coffee can. We started out by getting a mouse trap and putting it on a piece of wood so it could sit on the ground and not wobble when we pulled it back. Doing this helped out a lot by stabilizing the catapult so it would shoot straight. Our catapult arm was a five inch piece of wood and a spoon at the top so the ball could sit on it as we pulled it back to launch it. The spoon added a little bit of whip to it so the ball went higher and not so straight. We connected the piece of wood to the mouse trap and had stoppers so the arm wouldn't swing to far forward. We had many trial and errors to figure out how big to make the stopper so we could pull it back a certain length so it would shoot three meters. The only thing we had to worry about was where to aim it. But it wasn't a problem for me... I made it first try. No big deal. Anyways, our catapult was a great success!

Our design started last year when we built a mouse trap car for engineering. Its was a good design but we really wanted something that would get to the finish line. Well that didn't happen. We used CD's as wheels because thats the only thing we could think of at the time. Our body of the car was made out of cardboard which was a good idea because its light and strong. With a little elbow grease and some hot glue our body was done. Our mousetrap car moved by a pencil attached to a mouse trap which was also connected to the back axel. Even though the cardboard was tough the glue had a hard time sticking to it. Also the front right wheel feel off countless times. The glue didn't like the CD texture. Our mouse trap car would veer to the right because the wheels weren't straight. My partner and I had to point the car to the right so it wouldn't go off the track. Henry and I worked great with each other like usual. We had some great ideas and some not so good ideas. We each had tasks that we had to do and we would always ask each other if this would be a good thing to add or not. Overall I had a blast making this mousetrap car and I can't wait to make a catapult.

Over the past couple months, Mosaic has lead me in ways that I never thought I could go. I have made two board games, learned about casinos, and learned the history behind origami. Pretty interesting right? Well, the beginning of the year was a slow start but when I heard about the new thing called bolts, I immediately jumped on that. My first round of bolts was a huge success.
I took an independent study class out side of mosaic, which was American Lit. I read One Flew Over the Cuckoo's Nest, Fahrenheit 451, and Fight Club. I also watched the Band of Brothers series and that really changed my thinking on World War II. We ended up writting three papers and worked on a moral/historical criticism paper.
This was a big year for politics. I ended up joining an inquiry block that involved politics. We took a quiz that determined our political standings and I ended up being in the Liberalism party. We picked seven topics to research with our group and at the end of the inquiry block we had to right up a political manifesto.
For the bolts, I did Vegas Baby 1 and 2, Origami Folding Party, and Visualize this. This was a good way to get credit, but hey I had an amazing time doing it and I can't wait to start more up next semester.
Overall this semester was a good one. I learned stuff from how to rigth better papers, new math skills, and a lot about politics! The cool thing about learning about politcis is that I can keep up when my parents are talking about it. I can't wait to keep up my hard work and start my last semester as a junior!

This inquiry block was almost a successes. A few of my successes were, my reasearch and my closed questions. A couple of my hurdels was that I got sick for a week and I didnt work on my inquiry block so that put me back a whole week and I had to rush to put together my final presentation. A few changes I would make would be to meet as a whole group a few more times and and share what work we have done.
The past two weeks have been the best way to start a new school year. The two weeks haven't been like the year before or the year before that. We have done some brain activities that vary from the guided inquiry blocks to the "Olympic Games." The Olympic Games have helped us get back into the swing of things and start another good year in Mosaic. Our first guided inquiry block really helped our brains get going. We had our one question that we chose and you had to come up with 10-15 closed questions and answer those. Overall I feel like this will be a good school year.

Over the last nine months I realized joining Mosaic would not be as easy as I thought. My struggles began at the beginning of the year by not understanding and organizing my time. As the year went on I figured out that it was up to me to schedule meetings with my teachers and complete work during class time. After parent teacher conferences I realized that it was only up to me to complete my assignments and in class work on time. This means I needed to reach out to teachers when I didn't understand something.
As the year went on, I knew that I had to make better choices to be on track. This meant that I needed to work more at home on long term projects.
As I look forward to next year I know whats expected of me and what to expect. This means I will look into Future Business Leaders of America because I would like to pursue a Business/PGA Management Degree. I look forward to my Junior year in Mosaic.
