Data Table for group # 502

Week 1:

  Hypothesis H1

Conclusion about H1
Hypothesis H2
White cells are non-living waste produced by red cells.
Conclusion about H2
Hypothesis H3

Conclusion about H3
Experiment E1
Remove white cells off of plate and atempt to grow without any red cell on a separate petri dish.
Result for E1
White cells grew in colonies.
Prediction for E1 given H1
Prediction for E1 given H2
If the hypothesis is correct, then no growth should result.
Prediction for E1 given H3
Experiment E2
Remove some red cells and try to grow on a separate petri dish.
Result for E2
White cells re now on petri dish surrounding red cells.
Prediction for E2 given H1
Prediction for E2 given H2
If the hypothesis is correct, then both red and white cells would appear on the new petri dish.
Prediction for E2 given H3
Experiment E3
Remove both red and white cells from given culture. These cells would then be placed on a seperate petri dish.
Result for E3
Red cells show signs of little or no growth. White cells on petri dish show growth on the outside of the red cells.
Prediction for E3 given H1
Prediction for E3 given H2
More white cells will increase in number so that they will be more numerous than the red cells.
Prediction for E3 given H3
Experiment E4

Result for E4
Prediction for E4 given H1
Prediction for E4 given H2
Prediction for E4 given H3
Experiment E5

Result for E5
Prediction for E5 given H1
Prediction for E5 given H2
Prediction for E5 given H3
Experiment E6

Result for E6
Prediction for E6 given H1
Prediction for E6 given H2
Prediction for E6 given H3


Week 2:

  Hypothesis H1

Conclusion about H1
Hypothesis H2
White cells are non-living waste produced by red cells.
Conclusion about H2
It can be concluded that white cells are not a waste product but that they are living. This can be seen from the fact that the white cells grew in more than one experiment.
Hypothesis H3
Red cells grow both red and white cells, but white cells only grow white cells.
Conclusion about H3
It can be concluded that red cells grow both red and white. This was seen many times during the experiment. Because no red cells grew from the white cells, this hypothesis is correct. The pink cells that showed up in the white cells after two weeks is most likely due to experimental error. This is shown in the fact that not all white cells cultures grew pink centers. The benifits of these results is that scientists can grow only white yeast cells when needed.
Experiment E1
Place both red and white cells on a petri dish, but in seperate places on that dish.
Result for E1
The red cells grew both red and white, but the white cells grew only white.
Prediction for E1 given H1
Prediction for E1 given H2
Red cells will grow both red and white. To disprove hypothesis 2, white cells will continue to grow only white.
Prediction for E1 given H3
White cells on dish will grow only white but red cells will grow both red and white cells.
Experiment E2
Place red cells on a new petri dish.
Result for E2
These cells grew both red and white cells.
Prediction for E2 given H1
Prediction for E2 given H2
Red cells will produce both red and white cells.
Prediction for E2 given H3
Red cells will produce both red and white cells.
Experiment E3
Continue to grow white cells from week one.
Result for E3
White cells grew but produced a pink center. This is mostlikely due to experimental error.
Prediction for E3 given H1
Prediction for E3 given H2
The white cells will continue to produce only white cells.
Prediction for E3 given H3
Because this experiment involves only H2, there is no prediction here.
Experiment E4

Result for E4
Prediction for E4 given H1
Prediction for E4 given H2
Prediction for E4 given H3
Experiment E5

Result for E5
Prediction for E5 given H1
Prediction for E5 given H2
Prediction for E5 given H3
Experiment E6

Result for E6
Prediction for E6 given H1
Prediction for E6 given H2
Prediction for E6 given H3
