Period 4

Today in class, what we did was we were talking about what we did on Friday, the graphs. then Mr. Finley asked us, how much bacteria is in this area? (the petridish.) The answer came out to be for just one book is 1/9 of 1 box. The answer is 1/9 of 1 box is that 1/9/7 so u do 1/9*1/7=1/63...20.015 so you move the decimal 2 places so it would be 2001.5. So the percent would be 1.5%. then we did 1 1/2 which equals the amount of spaces the bacteria holds up divide by 7 equals 3/14 or 21.4%. Once we were done with that, we got out our perridish. In my group i had Elizabeth, Mary-Kate, and Ariel, so we got a marker and drew the outline of where the bacteria is. once we were done with that we had to copy a graph that Mr. Finley drew on the board the days and the height of something (he didnt tell us) then what we had to do was calcuate the percents of the aamountof spots of bacteria.
