February 4 Period 8

Today we started by taking qualitative notes on our experiment. Our contolled variable was type of water (Distilled & Bottled Water). Today was Day 4. Our data was:

• Cap pushed up on bottled water tube
• Cap stayed same for distlled water tube
• Big clump of yeast on top of water in distilled tube
• Almost no yeast on the sides of both tubes
• Even less water in distilled tube
• More yeast on bottom of distilled than bottled
• Not much yeast on top of either tube
• Bottled water tube got more murky

Next we looked at 4 line graphs in which the x-axis was temperature, and the y-axis was the rate of metabolism. One was a "U" shape, one was straight, one going from bottom to top then plummeting, and one from top to bottom. The 1st question he asked us was which showed change. All but the straight one showed change because both varibles must be adjusted in order for it to be "changed". The 2nd question was which one showed the path for cellular respiration. This was the one that went from the bottom to the top because it shows the correct path for cellular respiration. Next Finley filled up ballons with different temperature CO2 ballons.

Red- Super hot

Yellow- Medium temp/warm

Green- Mix of yellow & blue

Blue- Super cold

After this he apologized for cutting our quiz time short and everybody got them back, unmarked. We had the remainder of the class to finish our report. Finally, the class was over. Do your lab report!!!
