Week Three



In lab, we looked at forces. We were able to look at a steel and aluminum ball. At first, I thought that the steel ball would drop faster than the aluminum ball because it weighed more. When we dropped them, they both landed at the same time. This confused me. But after some explanation, I learned that yes, the force of gravity pulls harder on the heavier object, but it is harder for the heavier object to accelerate. So they land at the same time because the lighter object accelerates faster, so the two balls land at the same time. Then, we looked at how the force of a push affects how long it takes for someone to swing back and forth. We placed our data in the picture at the top.

Week Three!

  What did you learn this week? This week we began by talking about the NGSS unit development assignment. Then we transitioned to sharing our reading reflections from the week prior. After that, we worked our way into learning about lesson segments. Lesson segments can differ based on their order of them. We learned that a teacher can use experience and intuition to plan the order of instruction. After we talked about lesson segments we began to talk about the 5E's. These are engage, explore, explain, extend, and evaluate. Engage is students' interest to learn is piqued. Explore is when students ask questions to understand and interact with hands-on activities. Explain is putting your theories to the test and it is more collaboratively. Extending is problem-solving and drawing conclusions. Evaluation is rethinking what you have learned and proving learning through writing, conversation, and demonstration. Are you able to relate what you learned to what you already knew? I hones...

Week One!

 This week in the lab, we originally discussed the NGSS. The NGSS (Next Generation Science Standards) are standards that were solidified in 2013. It helps students begin to think more critically about science versus getting an answer that is immediately wrong or right. Later in the lab we then talked about cells and the different characteristics of living things. We talked about the eight main characteristics of living things. These include Cellular composition, genetics and heredity, maintaining homeostasis, growth and change, movement, response to stimuli, metabolism, and reproduction. After discussing these eight things we then made a colorful chart with images to help show our learning. I was able to relate most of these things to what I already knew. I knew about characteristics of living things but I do not believe I would have been able to list all eight characteristics of them. Other than that, this lab was a good refresher on things that I will need to know for this class....

Week Two!

     This week, we learned about seed germination. We learned how the life of a plant begins as a seed. We also learned a lot about the different parts of a seed and how seed germination really works. We went through all of the different stages of germination in full and great detail. After we discussed how seed germination works, we began to talk about viruses. We talked about whether viruses were living or nonliving and how we can determine this. Prof. said how she believed viruses were non-living and we talked about the stages of viruses as well.     I feel like I was able to relate some of this to what I had previously known. I feel like I remember learning about seed germination when I was in elementary or maybe even middle school. That was so long ago that I feel like I did not remember half of it. I also feel like I did not know how seed germination worked in depth as we talked about in class. I do not feel like I knew all of the stages of how it really w...
