Prehistoric Chemistry
Evidence of Work
Description: For this project we had to make a board game and incorporate chemical reactions. After doing some brainstorming, we came up with a dinosaur theme and called our game ¨Prehistoric Chemistry¨. We included four reactions - two synthesis reactions+lighting on LED, double displacement reaction, and production of gas. For each reaction, we had a different little set up and if you were the first to land on the "special" dinosaur spot, you were the first to set the reaction off. Then the final reaction was for the first person to finish the game and the player was able to set off the best reaction, elephant toothpaste. We put a lot of specific detail into our Board game and every reaction was throughly though out.
Content
Each chemical reaction had to have a dominoe effect. For example, in our double displacement reaction (first reaction), a marble rolled down a ramp and hit a latch. That latch then hit another marble which also rolled down a ramp and hit a tube filled with a solution. The tube tipped over and the solution flowed into a funnel and onto a dish filled with another chemical. Another piece of our board was the single placement reaction and LED light bulb (second reaction), where we placed three dominoes on the large Popsicle stick, fill up one of the small tubes with copper chloride. Then place the tube in front of the line on the Popsicle stick. Put the arduino board next to the paper dish and attach both clips to a piece of aluminum foil and place over the paper dish. The reaction cut the foil and allowed for a complete circuit and eventually turned the lightbulb on. Single Replacement Reaction or our (third reaction), we fill the tube that is attached to the paper cup with nitric acid. Place the paper cup with the tube attached, against the foam ramp so that the foam goes inside the cup. Put a chunk of zinc up against the small block of wood (between the cup and the wood). For our production of gas (fourth reaction), we had a reaction to set off elephant toothpaste. We fill the graduated cylinder with a mix of 15 mL of hydrogen peroxide liquid and 5 mL of dish soap and then filled our 5 mL of potassium iodide into the purple cup. If fell into the volcano and the explosion occurred for the winner of the game.
Reflection
Overall, I thought that this was a very successful project. My group and I worked very well together and with our minimal amount of time, we completed a lot. We got over our problems together the best way possible. Like, most of the time we all had to come together and share all our ideas to figure out our next step would be. With that, we figured out who would work on what steps and that everyone had the same amount of work to do in the group. We did a good job preparing but had some trouble pursuing what we wanted. You juts have to keep trying new things that could possibly work, which was a big theme for this project. One peak for me was patience and self-control. Like taking a step back from something and gaining patience when something goes wrong. I would go work on some other part, so we would all contribute to the project together. Another peak for me was just coming up with new ideas throughout the project. I would just begin building and it would soon turn into something that could possibly work for one of the reactions. One pit for me was mainly, staying on task. I liked to always wonder around and see other peoples projects and just talk to everyone around me. I could get off track really easily and that is one pit that I need to get better on. Another pit that I encountered was time management. We were going really slow in the beginning and in the end, we were rushing left and right to get some things done. My group had to come in on the weekend to finish up because we lost so much time. Our group literally finished the project minutes before presenting in front of everyone. This was definitely one of the most intense of all the projects. This is always something that happens and I just have to keep working on it.
