week 5 blog post

In Lab for Week 5, we worked on force and talked about energy and it's focuses. To Discover this we reviewed a pendulum simulation that was swinging back and forth and through a energy lens we were to figure out and look into why a swing slows down and stops sometimes. I took away and came to the conclusion that the pendulum collides with air particles which then speeds the particles up then slows down the pendulum. The collisions transferred energy to the pendulum that is taken from the air actually. From then on we took the ideas of thinking through energy lens into other ways, when another big question example about how we need to keep pushing a child on swing to keep their momentum going. This is due to the collisions with air particles that transfer energy from rider to surrounding air that gets in the way.

We also discussed and reviewed what would happen if something fell straight down into a bowl. We were instructed to build something that would stop an egg from breaking when getting dropped. Our first task was to prevent an egg from dropping when dropped from a height of one meter. We were to design how we would do this, where if we failed we then redesigned and then re tested to see if we could change the outcome. My group and I therefore had to consider what changes we would do to change the original outcome! This also represents Newton's Law because once the egg is dropped gravity causes the egg to accelerate down creating force against the bowl once there is impact.

What we did in Monday's Lab : talked about how can we support play that is exciting but not dangerous but this time in the lab we primarily focused on the question of what affects a rider's speed down a slide? By table group, we ended up putting this question to the test where we designed and conducted our own investigation where we also were to support everything with evidence when we could as well. I took away and learned that, What could affect variables of speed down a slide: - rider weight, slide material, rider clothing, initial force of push. for our investigation we decided to focus on slide material. - our question was how does the material of a slide change the speed of a rider? we found that the smoother the material the faster the object would move. The materials we used were wood, plastic, foil, and ceran wrap. This was an interesting investigation that proved that different materials affect a riders speed. What we did in T hursday's Lecture : In the lectu...

Week 4 Blog Post

In the lab for week 4, we talked a lot about friction and forces. We were reminded that friction is the force that opposes sliding across a surface. Well, today we modeled the question in the lab through investigation in the lab that asked, "What affects how long it takes a swing to go back and forth?". So today in the lab we designed an investigation that had us test this theory out. My group claimed that the faster we push the swing the quicker it will go back and forth. We effectively proved that to be true with our data. We noticed that when we bumped the swing the time it took to go 10 swings took a lot longer then when we pushed the swing harder. In a lecture for week 4, we talked a lot about force and Newton's First Law. I was reminded that Newton's First Law states that without an external force, an object will maintain its speed and direction of motion. Then we went into Newton's second law. Newton's Second law states that larger masses are harder to ...

Lab : In the lab for week 7, we were designed to physically build a model of the sun, moon, and the four inner planets. We were instructed that this needed to be by scale. The hardest part was getting each of the planets, the sun, and the moon to be the exactly correct size that it would relate to in real life. We then had to space out all 6 of those in the correct distance that it would be in real life as well. After lots of errors and trials, we finally got all 6 of them to the right distance. Overall, I take away from this investigation just how spread out the moon is from the sun. It was a good way to hands-on work on this by visually being able to tell how spread out everything truly is. Weekly Textbook Reading : Our Solar System- The four inner planets are Mercury, Venus, Earth, and Mars. They are all considered rocky planets because they have a solid outer surface, this was a helpful reminder once again. It was most helpful reading on the section regarding the Sizes and Distance...
