My Science Midyear Benchmark
Last week, we took a benchmark test in Science class. I scored an 88 on the benchmark.
Here's my item analysis:
What I noticed about the questions that I got wrong is that two out of the three of them are about the layers of the earth. I'm not totally surprised that I missed those: We studied the layers of the earth a long time ago. But it does mean that I need to go back and check that content out again. That's worth reviewing for sure.
I think I'm most disappointed in myself for missing question 25. It asked why the inner core of the earth is a solid ball of iron. I answered that it was because of extreme temperature. I should have realized that when I want something -- think snow or sand -- to be "more solid," I don't add heat to it. Instead, I add pressure to it. I think that's a question that I could have gotten right if I had thought a little more carefully.
What I'm proud of, though, is that I made mastery on almost all of my other objectives. What I do the best is ecosystems stuff. Food chains and food webs are easy for me -- and I'm also good at biotic and abiotic factors.
I think what I enjoy the most is talking about how humans impact the environment. That stuff is really interesting to me simply because I know that humans are having an impact and if we think about our choices, we can make sure that our impact is a positive one instead of a negative one.
