What did I learn?
I learned how to serve backhand and how to rally.
What did I do?
I served and played games, and then practiced the moves for badminton.
What worked?
Playing games, because it gave me more experience in playing games.
What didn’t work?
It didn’t work when we just practiced the moves because we always ended up playing games.
Personal Relevance
This will help me because now I know how to play more sports.
What did I do?
I made a model of a rollercoaster, collected the data, and made a video of the science behind the rollercoaster model. I also used the collected data to make a lap report.
What did I learn?
I learned about the Law of Conservation of Energy, the relationship between kinetic energy and height, and systems. Last but not least, I also learned about the system
What worked?
When the part in the rollercoaster kept making the marble fly out of the track, it worked really well when we added extra protection walls besides the large tube.
What didn’t work?
When the part in the rollercoaster kept making the marble fly out of the track, it worked even worse when we just only added a chair to stablelise it.
Personal Relevance: This is important because I learned a lot about energy and how to use it, including how it works.

What did I do?
Me and my partner Grace built a balloon car made of styrofoam, straws, a balloon and a lot of tape. We used the balloon car to learn about forces.
What did I learn?
I learned about:
Newton’s first law, which is an object’s state will not change unless acted on by another force, which works on the balloon car because the balloon car will not move unless we blow air into the balloon and it moves.
Newton’s second law, which is F=ma, which means force equals mass multiplied by acceleration. This is shown in the balloon car when the more washers there are on the car, the slower the car goes.
Newton’s third law, which is that for every action, there is an equal and opposite reaction, and that is seen in the balloon car when I blow the air into it and it moves.
What worked:
At first, the car wasn’t moving, so then we had to un-assemble it to cut off the bits next to the wheels for it to spin regularly.
What didn’t work:
I didn’t work when we tried to make the wheels further from the car body because it was still stuck to the body.
Personal Relevance:
This project taught me how to use the Newtons’ laws in crafts, and this will be helpful in multiple projects.
What did I do?
I used paper and created a crumple zone, to lessen the the force on the egg. One of the most important things in my egg car is the drape that wrapped around the egg to protect it.
What did I learn?
I learned about Newton’s laws and how they applied to the egg cart. For example, the egg car would not move unless I made it move using the ramp and it went down and it stopped when it hit the
What worked?
It worked when I used a drape like thing to cover the egg, which made it safer in the egg car. In addition, the crumple zone attached to the front of the car, which lessen the force applied onto the car.
What didn’t work?
It didn’t work when I tried to add crumpled paper to protect the egg because the paper didn’t cushion the egg at all because it was hard.
Personal Relevance
This will be helpful in later life when I am working on how to make cars safer, or putting a safety idea to protect people from car accidents.
What did I learn:
I learned and practiced breaststroke, backstroke, and freestyle. I also learned how to do the essential hand signals for scuba diving.
What worked:
It worked when we went under water to practice.
What didn’t:
It did not work when we were learning how to do it above land
Personal relevance:
It will help when I am snorkeling and in trouble.
Understanding puberty changes is important so that you can understand that your body is changing and acting more mature and understanding.
I am confident about the mood swings because I am really good at holding my feeling and then letting them all out at the same time because then I won’t have to have giant emotional breakdowns but I can let them out little by little.
I am concerned about periods because I heard that they can hurt a lot and about the products that they can cause infections if you don’t clean them properly.
I have to look at the source, because the source has the clearest information on whether the information is credible or not. For example:”natgeo.org”
I want to be a better communicator because I am always very awkward around new people or those I’m not very friendly with.
What are we doing?
Writing a fictional story based on a theme that matters to me.
What are we learning?
Theme is what we learned first, which is the moral of the story but you have to look through the story for the theme, for example; teamwork make the dreamwork, or love is all powerful, you can’t be defeated if you have a strong heart.
Character Development: The process of creating and evolving a fictional character to make them believable and relatable, which is the girl in the story that lost her parents and is willing to do anything to avenge them.
Plot : The chronological events that shows what happens and why it happens, maybe including a plot twist and some backstory of the protagonist and antagonist.
Setting: The place where my story stays in and one of the most important things in my story. The whole story wouldn’t work if I hadn’t added my setting which is the background where my protagonist met the most important supporting character.
What’s working?
Something that I’m really proud of about my story was that I was very detailed in my story, especially the part where the characters went through the temple and saw the Diamond of truth for the first time.
Personal Relevance
I really enjoyed writing this story because it was a lot of fun, and I liked that it really revolved around my theme, which is that friends can be made of the least likely material.
I stepped out, and stuck out my right hand and used the front side of my hand to serve. I feel like I did my preparation for the better than the actual serving part.
I just aim my hand where i want the ball to go and then the ball usually goes where i want it to go.
I couldn’t always get the ball over because i would get nervous that it would go over the net.
My stance and arm movement made sure that i was facing forward and my arm wouldn’t move where it wasn’t supposed to go.
I can practice how to underhand serve at home because i have a ball at home and i can practice outside because i have a small net.
What did I do?
I used many different colored tiles to create routes for the robot car named INDI and made my critical thinking stronger by figuring out solid ideas on how to make it easier for INDI to stick to the tracks me and my partners organized based on the challenge cards.
Eg: Red is stop, and green is forward.
What did I learn?
I learned how to make the INDI car stick to the track and how to fix it if it doesn’t follow the programmed steps as expected.
What worked?
When we where trying to get INDI to stick to the tracks we found that INDI followed the routes better if we put them not too close and not too far together so that INDI can sty on track.
What didn’t work?
It didn’t work to make INDI go around with each block spaced out because INDI could go off course and not reach the surprise block.
Personal Relevance
This is useful because then I can do basic programming so now i know the basics.
