  The big question addressed in lab, and a description of what you did. The big question that was answered in the lab was what surface is best for a playground. We created and designed a bowl with materials in the bowl that would protect the egg from breaking. Our group decided to put sand, not tightly packed, and a double layer of saran wrap. We successfully dropped the egg from 1 meter to 2 meters without a break in the egg. This was one of my favorite labs we have done so far because dropping the egg and seeing if our ideas were right was fascinating. 2. In our lecture this week...     We took our exam on the first 5 weeks of this semester.  3. Pressbook:      I think it was exciting designing these playground surfaces because there are so many different surfaces that are used for a playground, but the only groups in my lab that were successful with dropping the egg from 2 meters were the ones that used sand. So how does the idea that there are so m...

  The big question addressed in lab, and a description of what you did. This week in the lab, we discussed swings and which item would fall faster to the ground. We discussed and chose to experiment the length of the chain, and whether the length of the chain completes more swings if its shorter or longer. So first, we created a question and hypothesis, which is shown in the picture below. Then we cut two strings to different lenths and tied them to two washers to model the swing. After that, we clamped a wooden rod to the tale and hung out swings from the wooden rod. We then set a 5 second timer and track how many times there was a completed swing. We then found out our hypothesis was right that the shorter chain did more swings in 5 seconds than the longer chain.  A description of what you learned in Thursday's lecture. In lecture this week, we talked about more motion and the direction of the arrows when a swing is in motion. We also talked about energy and what is energy. ...

  The big question addressed in lab, and a description of what you did.           The question my group decided on was how weight impacts your speed. First, we figured out all the logistics like the slop, height, and length of the slide. Then we weighed our canister and the weights. After this, we place 4 weights in one canister as our tester 1 and 6 weights in the other canister as our tester 2. Then we raced them. We had a timer timing when it left my hand till it hit the bottom. We then decided to do more runs because we didn't understand the data. In the end, we figured out that statistically weight does not impact how fast you you go down a slide.  A description of what you learned in Thursday's lecture?               In Thursday's lecture, we discuss friction and the idea of friction. We also discussed the forces on an object and where the arrows would be. We talked about the direction of the arro...

The big question addressed in lab, and a description of what you did.  In class this week we got to create a race where one student, the slower student, would get a head start if they were racing. We had to figure out how much time or the length the person would get as a head start. I think it was really interesting when we were trying to figure it out because some people had them walk, and some people had them hopping on one foot, which made it hard when we did the full group race.  A description of what you learned in Thursday's lecture. In Thursday's lecture, we talked about how much of a head start each of the things would get. For example, we talked about if the bike or the car would get a head start, and how much that head start would be to the destination. In the end, we figured out the formula that we would use.  Answer questions about the weekly textbook reading: What did you learn? In this week's textbook, we learned about motion, distance, and position and...
