Blog Post Week #4

 

  1. The big question addressed in lab, and a description of what you did.
    1. This weeks lab we switched focus from slides to swings. The big question was, "What affects how long it takes for a swing to go back and forth?" The variable we chose this week was weight. We tested this by measuring the time it took to swing back and forth one time while adding weight each time. After many tests, we found that the weight does not matter and the time will always be roughly the same. 
  2. A description of what you learned in Thursday's lecture.
    1. In lecture we investigated, rider weight and the length of rope or chain. We found that the riders weight does not affect the period of a swing. Next we focused on the length of the rope or chain and we found that the longer the rope, the longer the period will be. Bottom line, period does not depend on rider weight, period does depend on the chain or rope length, and a longer swing equals a longer period. 
  3. Answer questions about the weekly textbook reading:
    1. What did you learn?
      1. Something I found fascinating was the the different kinds of energy. Learning that kinetic energy is at the bottom most part of the swing, and potential energy is at the top was very interesting. This is something I did not know before and will help me when teaching it in the future. 
    2. What was most helpful?
      1. I think this was also the most helpful. The physics behind swings can be difficult to understand and the textbook really helped. It was also nice to be able to go over it during lab and lecture as well. 
    3. What do you need more information on?
      1. Something I need more information on would be what my group tested, why the weight does not have an affect on the period. You would think that weight is creating more momentum when that is not the case. 
    4. What questions/concerns/comments do you have?
      1. I do not have any questions or concerns or comments at this time!

Week #6 Blog Post

 - Something we learned about this week was pollination. It was really cool to check in on our fast plants and use them for self pollination. We noticed that our plants were growing significantly! After checking in, we used dead bees to self pollinate these plants. We also did an activity where we learned about the turtles and their chance of living. That interactive activity was a ton of fun! - Prior to class, I knew about turtles and that they lay their eggs on the beach. I was not aware of how many eggs they lay at once, and I didn't know it was not in the turtles favor that they are going to survive! - I can apply this to my future teaching career by using the same activity we used to learn about turtles. I think it teaches a good lesson of for the students that the world can be very dangerous to animals. It was also important to learn about the impacts humans make and how difficult they make it for the animals.
