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 |

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 |
