In the badminton unit, we learned about how to do a legal overhand serve. we can do this by bring the ball in front of our racket and hitting it really hard. This can bring the opponent very far away. it is also fast, so the opponent has to react very quick.
We worked on an “Otzi Trial” to decide whether Otzi was murdered or not. First, we studied how Otzi was found and when Otzi had died. Then, we studied the copper ages, which is when Otzi died. Finally, when hosted a trial with arguments to say whether Otzi was murdered or not.
What did we learn?
We learned about the essential question “why should we care about the past?” We also learned that there were 3 ages, especially the Copper Age. We researched about the condition of Otzi and how he could have possibly died.
What worked well?
I think that the trial worked well because we had interesting discussions and good claims. The teams worked hard to try to get expert witnesses to say something that could help them. The witnesses also did very good when presenting because their claims were good and believable
What didn’t work well?
What didn’t work was that I was not really prepared for some of the questions I didn’t read about. Another thing was that I could have used my graph more. I could have made it better with clearer models.
What are we doing?
I think that Otzi was very important because he can tell us about how people lived during the Copper Age. I also think that discussing how Otzi was murdered was also fun. Otzi is a crucial part of history, and he was very interesting.
We had to create a car with paper, wheels, a straw and a 1 meter of tape. We also only had 2 days and couldn’t build any parachutes or anything to slow the car.
What did I learn?
Newton’s 1 law states that the concrete wall will hit back with an equal force so I built a crumple zone to reduce the force that will reach the egg.
What worked?
The crumple zone worked really well and it stopped most of the force that reached the egg, and it also didn’t crack. the seat belt also prevented it from flying out.
What didn’t work?
The wheels were a bit funky, and it didn’t move, so we took off the rubber. Then it went good and fast.
Personal revelance
It helps us to under stand how cars help our safety and how we should react to it and how cars protect us.
The balloon car was built using a balloon, two straws, a foam plate and 4 wheels. We used it to learn about Newton’s second law by putting weights on it and looking at how far it travels and compare it to the other distances with more or less weights. As we added more weights on the car, it moved less and less, which explains Newton’s second law F=MA
What did I learn:
I learned about Newtons laws which talks about gravity and forces. Newton’s 1 law is the law of inertia, which says “an object in motion tends to stay in motion, an object at rest stays at rest unless acted on by an unbalanced force”. Newton’s 2 law states that Force is Mass times Acceleration, or F=MA. Newton’s 3rd law is that an object stays in the same motion unless acted on.
What Worked?
I problem solved how to make a balloon car faster and make it work. I also problem solved how the type of weights affect the distance the car goes.
What did not work?
I struggled when our balloon car did not go. Then I figured out the problem, which was that the straw was pointing the wrong way . it blew to the ground, and could not go anywhere
Personnel relevance
Today’s learning will help me better understand why things go that way, or even solve problems including Newton’s laws.
I learned how enter the pool using the giant stride technique. and I also learned how to dive down when using a snorkel and how to blow out water from your snorkel.
