Blog Post Week #2 Segal, James

 

  1. The big question addressed in lab, and a description of what you did.
- The big question this week in lab that we addressed was, "How can we support play that is exciting but not dangerous?" This week in lab we did a very fun activity where we were measuring time, and distance, so we could calculate speed. As a table group we had one person jog at 5 different distances to get her average speed. Then when we were put up against another group, we used the average time to see how much of a head start one of the two races needed to finish at the same time. We were one of the only groups to have the two racers finish at the same time!
  1. A description of what you learned in Thursday's lecture.
- In lecture we went over what we did in lab to start. First we talked about the SEP's in lab. Which consisted of making observations about motion, measured distance, time, and calculated speed, as well as used models. Then we focused on the DCI's which included learning that motion can be described, measured, and predicted. Next we focused on races and doing math to figure out how much of a head start one of the racers would need to finish at the same time. We can used an equation for this, time head start= /s. Then for the next problem we used the equation t= 5 miles/20mph= 1/4 hr. This helped us figure out the that Jeff would need to leave 5 minutes earlier. When measuring motion we use, speed= distance/time. After this we discussed measuring speed, distance, and time. This is where we focused on imperial units, and metric units. To end lecture, we focused on representing patterns in motion. 
  1. Answer questions about the weekly textbook reading:
    1. What did you learn?
      1. My biggest take away from the textbook reading this week was the information learned about Position and distance. Distance is described as how far one travels, and position is a singular point. 
    2. What was most helpful?
      1. Something I found to be the most helpful was learning about motion. This is something I always struggled with growing up in science class. Going over change in motion was something I needed to be reminded of. 
    3. What do you need more information on?
      1. Something that confused me was velocity. This is something I would like to learn more about or even go over in class. 
    4. What questions/concerns/comments do you have?
      1. I do not have any questions at this point. I''m sure I will in the future!

 - 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.
