We made snowflake crisps using math. First, we decided on what we are making and buying, and got the recipe with the price online. Second, we add up the price of each ingredient and divided the price with the number of servings and got the price per serving. Then, we marked up the price by 100% and rounded it to a whole number to get the final price. Last, we made the snowflake crisps and sold all of them.
What did we learn?
We learned how to mark up the price by X%, and how to change the cups to grams. We used a graph for the changing, for example, 1/2cups=2.5grams for calculating. We also learned how to round different prices to different numbers.
What worked?
I am proud of promoting our baked goods to people and proud of doing the calculations. Our change of unit also worked very well and we got a lot of profit. We are all proud of working together calculating precisely.
What did not work?
During work time, we were working a bit slower than other people. If I were to do this unit again, I would be more focused and would be working faster to make more progress.

This unit helped me learn about how to calculate many things for a sell. If I were to sell things in the future, I would use those skills to help me. For example, now I know how to calculate a profit and can do it in the future.
The criteria of the egg car is: Width has to be shorter that 6.5cm, length has to be shorter that 16.5cm, can only use 1m of tape and 3 pieces of paper.
What did I learn?
I learned that newton’s first law is seen when the egg car bumps onto the wall, because that an object at rest stays at rest, an object in motion remains in motion, unless acted on by an outside force. I also saw how newton’s third law worked when the egg cracks, because that what goes up, must come down, same with the egg cause it is pushing to the wall and the wall is pushing out. Lastly, newtons second law states that the greater the mass of an object, the more force needed to accelerate it, and that shows how a fake egg works well, but the real egg cracks/flys out.
What worked?
The seat belt we made prevented the egg from flying out. Also, we made the crumple longer so that the egg wouldn’t crack.
What did not work?
I noticed that the two holes we made for the wheels had friction with the egg and made the egg crack. Next time we can put the wheels on the car, instead of in the hole.

Now I know that it is important to put on seatbelts, because that you may fly out during an accident according to newton’s first law. I also know that in the future, cars can make longer crumple zones so that people in the car won’t get smashed according to newton’s third law. Since now I know the three laws, I would tell more people in the future to put on seatbelts and watch out for accidents.
The balloon cart was built using a balloon, a plate, some bottle caps, and some straws. We used it to learn about how Newton’s 2nd law worked. After we built the balloon cart, we added washers and measured how far the cart went with the same amount of air. After this experiment, we learned that the greater the mass of an object, the more force needed to accelerate it, and that is how we learned the newton’s second law.
What did I learn?
Newton’s first law says that an object at rest stays at rest, and an object moving remains moving, unless acted on by an outside force. We saw this law in action with the balloon cart when it did not move, and remained at rest, unless the air in the balloon is released. Newton’d second law says that the greater the mass of an object, the more force needed to accelerate it. We saw this law in action with the balloon cart when it had more washers, the distance the cart drove was less that it had less washers when given the same amount of air.
What worked?
The car design worked well because that I shared my ideas with my partner and she shared hers with me. We both added more and more designs to the car when there is a problem. We had to test it again and again so that it is the best version.
What did not work?
It was a struggle when identifying the laws for the car. To solve this problem, me and my partner thought about the definition of the three laws and see which one conforms to the car. We also tested the car many times to identify the laws.

The balloon car is like an airplane in real world, when the balloon car’s air gives force to let the car move and how airplanes are the same. I see newton’s 3rd law in life when I throw the volleyball up high in the air. “What goes up must come down” perfectly describes the ball being thrown up in the air and bumping to the ground. It is important to know these laws because that it can help us avoid many accidents in life.
I am proud of making my plaster cake. It is a cute cake that I made with plaster. I smoothed the surface of the cake with my hand. I also used acrylic paint to color it. I am proud of this artwork because that it is cute and nice.
During the Campaign for the Olympics unit, I worked on writing a script and creating a presentation about why Los Angeles should be the host city for the summer Olympics, 2032. While presenting, I made eye contact and spoke with a loud and confident voice. Me and my partner added more details to our presentation when we thought something was missing.
What did I learn?
I learned that Olympics was originally created to honor the god Zeus. I also learned how to make a presentation more effective. We learned how to use AI effectively and learnt how to make a logo using AI (although it was very difficult).
What worked?
I found that working with a partner is more efficient. We can share many PPTs and make it easier and faster. I improved my eye contact and voice while practicing my presentation with my partner.
What did not work?
I found that I had many filler words like: and….. yeah, uh, um, ok….eh, etc. If I were to improve my presentation, I would take out my filler words and would be more confident. Next time, I will practice more and improve my sentences to take out my filler words.

The collaboration and communication skills I practiced during this unit for the future is that I learned how to communicate with my partner effectively. At first, we weren’t communicating effectively, but I found out soon and changed our way of communicating. I also learned how to speak loudly, and this would help me present my work later on in the future.
