This week in science
This week, (from 11/17 to 11/20 we learned about the bacteria growth. We forgot to count the boxes in the petri dish, so we couldn't compare. We than got a mini simulation about Truman and Jackson middle school. They asked us if Truman was better than Jackson in science. The problem was that they gave us misleading information. The information wasn't enough that they gave us. We did this to show how we couldn't compare any information by not counting the boxes in the petri dish. We also learned about graphing. The graphs have the independant variable on the x-axis, and on the y-axis, it is the dependant variable. That can help us compare. Then we also got to do a simulation on the computer. That compared the bacteria growth and the initial population. It showed how the bacteria grew as time went by. Now we have to graph the information. I think that Mr.Finley made us do this to show how we have to keep all of our data. We learned how to compare bacteria growth, and time. Next time we do an experiment, we have to keep track of all of our data.

This is good Drew you're very close. It wasn't that they boxes were important but that knowing the total populations (or area) is important so that you can make a comparison. I do want you to keep track of your data but more so I want you to understand how bacteria grow and what pattern you see in their growth rate. Also, is there any factor that affect this? Awesome job Drew. You're doing a great job!
