What did I do?

The criteria for the egg car was to design and build a car with a safety system that will deliver an egg safely down a ramp.

What did I learn?

We see Newton’s 1st law in action with the Egg Car when the car hits the block but the egg tries to keep on moving. Newton’s 1st law states an object at rest or in motion will stay at rest or in motion unless acted on by another force. We see Newton’s 3rd law in action in the egg car when the car hits the concrete wall, the wall will exerts a equal and opposite reaction to the car that hits the block.

What worked?

The building of the Egg Car worked well because our collaboration was very good. We were successful in the process where we had to design it. We tested it multiple times and fixed it so it can safely deliver the egg.

What did not work?

The testing of the Egg Car was not successful. To solve this problem I would add a better crumple zone, so it can decrease the chance of the egg car cracking. I would also make the car bigger so it’s harder for it to fly off.

Personal Relevance

It is important to know Newton’s Laws because the science is used to develop a crumple zone in a car so we can be safe while driving. We can also safely enjoy rollercoasters because engineers use Newton’s Laws. This is important in my life because I might be a engineer and this can help me when I have to buy a car.

What did I do?

The balloon car was built using 4 wheels, 2 axels, 2 straws, a balloon, a rubber band, tape, hot glue and a cardboard tray. The criteria was to build a car powered only by a balloon that can travel the farthest distance in a straight line. We used it to learn about Newton’s Laws. (The law of Inertia, The law of Acceleration, and The Law of Action and Reaction)

What did I learn?

Newton’s 1st law says that an object will stay at rest or stay in motion unless acted on by another force. We see this law in action with the balloon car when the car only move when we release the balloon, and it stays at rest when we don’t release it. Newton’s 2nd law says that acceleration of an object with constant mass is proportional to the net force action on it and is in the same direction of the net force. We see this law in action with the balloon car when we put more weight on the car, it won’t move as much as a car with less or no weight. Newton’s 3rd law says that all actions have an equal and opposite reaction. We see this law in action with the balloon car when air came out of the balloon, the car moved an equal amount.

What worked?

The process of building the car worked well because we were able to make the balloon car really fast and it was super light. We also successfully recorded the distance the car travelled with different amount of weights. Our teamwork was also pretty good when making the car.

What did not work?

It was a struggle when we first tested it as the car did not go and it kind of broke so we had to spend a lot of time fixing it. To solve this problem, we first taped the car tightly so it won’t break. Secondly, we put the balloon towards the end because it seemed to work better like that.

Personal Relevance

I see Newton’s 2nd law in real life when we drive cars because the more we push on the gas pedal, the faster the car will travel. The balloon car was like any other moving object in this world, as all of them use some sort of newton’s laws. (Cars, Rollercoasters, planes etc.) It is important to know these laws because it helps engineers and inventors to construct railways and tracks, and to build new vehicles.

I made a rollercoaster for a marble and our goal was to make it go as fast as possible.

I learned that the rollercoaster has to go down slightly so the marble won’t stop in the middle of the tracks.

We managed to make the marble from the beginning to the end smoothly without any troubles.

I struggled to make the marble roll fast as it was kind of slow for the entire time on the rollercoaster.

Today’s learning will help me on my collaboration skills and how to resolve problems.

1. What did I work on? 

During the campaign for the Olympics unit, I worked on researching our host Olympic city and country by using the SAS databases. I worked on improving my speaking skills. I worked on my positive collaboration skills with my chosen partner. I worked on using persuasive sentence frames to convince the IOC to select my host city/country for the 2036 summer Olympic games in Seoul, South Korea. I worked on memorizing my script and speaking loudly. I worked on creating a Canva presentation with six criterion slides and using SAS databases photos. 

2. What did I learn? Why do global sporting events exist? 

Global sporting events exist because they can unite countries positively and make global competitions. It can also boost the economy of the host country and showcase the country’s culture as well. The Olympics also provide entertainment and promote healthy new sports to the public. It also increases the wealth of companies as well as their stocks. 

3. What worked well? 

I am proud of my Canva presentation, as it was detailed and well made. I am also proud of my script as well as spending a lot of time on it and I think it was very detailed with key ideas. And I think I was successful with my logo design. 

4. What did not work well? 

Something that didn’t work well was the researching. It was hard finding the right information especially about food, and I spent a bit too much time on getting it done and I felt like I had to edit it quite a lot as I was practicing speaking. 

5. Personal Relevance 

Collaboration and communications skills are important for my future because when I am in university and in a job, I would need to work with other people to solve problems and make presentations.
