science fair graphs
Posted: Mon Jan 03, 2011 4:48 pm
I just showed my teacher my graphs and he shot them down. I did experiment where I had a slime mold and two possible paths for it to take with food at exit. I had two controls that didn't finish test. I had ten testing plates where 6 finished shortest path ( route 1), 0 took second path, and 4 I couldn't tell which came first because it had finished both when I looked.I did a bar graph where the vertical axis was path taken(1,2,or can't tell) and horizontal was how many test plates took each path. He said I should include controls? I did a second part where I put some slime mold and food at entrance and at exit and said which path showed thickest growth. I did pie graph showing 60% were thicker path 1, 0% path 2 and 40% were equal 1 and 2. He confused me trying to say how to change. Help!
