This week in science we worked some more on our murder crime project. Our role is a forensic scientist gathering evidence and then adding up all the evidence to a conclusion to find out which suspect killed the person. So far most of the evidence adds up to Stanley Wings. Mosie and I were assigned to interview Hiedi Seeki but she appeared to be safe. Then we took their favorite marker and took the marker that was used to write a note in the dead girl’s trash can and stuck them in acidic acid. Stanley Wings and the original marker had identical effects. Then we burned fabrics of a piece of red on the girl’s dead body and compared it to the other pieces of red fabric that the other suspects had. Again, Stanley Wings was identical to the original. We also looked at the fabrics under a microscope, we got the same result.

I found that if I’m ever trying to solve a mystery maybe I could use these ideas. It was very fun to look at the fabrics under the microscope. There were lots of little interesting fibers. I think I participated pretty well because it was something I enjoy doing. If I could’ve done something differently it would be to write more about the other suspects, not just Stanley Wings. I also would’ve included more about our other experiments. My three questions are, How long does it take a real forensic scientist to solve a crime, Are there more male forensic scientists than females, How much can you get paid for being a forensic scientist?

This week in science I actually did one thing in science before I got sick. We did a small experiment with mass over volume.  we had measuring cups of water and we would graph the water before we put the object in and after. Then we would weigh objects and measure the height and width. I learned that the size of the object that is put into water doesn’t matter. It’s actually the density. We also watched some weird lego video about mass over volume but I forgot the title of it. I didn’t really learn much from it because I’ve already watched it before. I also learned that matter is pretty much everything. It’s space, it’s the earth, it’s you.

I don’t think ill use this in my everyday life but ill probably use this in high school once or twice. it was pretty fun to try and fill up the water. We kept messing up the water level. I think we participated well but it was a little hard to understand the confusing graph. In the last couple of minutes, we started to understand it thought. But then our marble rolled under a table and we wasted our last few minutes getting it back out. That was pretty funny.

Who discovered mass over volume?

Why is it so confusing?

When was mass over volume discovered?
