Is it Alive?
Anna Louise, Xavier, and Madeleine
Questions We Tested
Does our unknown have cells? Does our unknown adapt? Can our unknown store/release energy? Does our unknown develop?
Experiment #1: Does it have cells? We made a wet mount slide with our
unknown and looked at it under the microscope
We could not discern any signs of cells We also made a dry slide of just our
unknown and we took this picture:
Experiment #2 and 3 : Does it adapt? Does it develop? We tested this question by putting our
unknown in freshwater, saltwater, and soil. We also made a constant.
The saltwater and freshwater were for testing if our unknown was a plant, animal, or fungi
The soil was for testing if it was a plant/ if it responded to the soil.
Freshwater
Saltwater Soil
Experiment # 4: Does it produce CO2? We put our unknown in a vial with some
water and a few drops of bromothymol blue.
We also made a constant by putting bromothymol blue in a vial without the unknown.
The purpose of this experiment was to test if the unknown made energy (every organism that makes energy produces trace amounts of CO2)
Results In Experiment 1, we found no trace of cells. We found
cube shaped things that did not resemble animal or plant cells
In Experiment 2 and 3, we saw no change or response to the different environments
In Experiment 4, we found that both vials remained blue and produced no CO2
Question Yes No

X
Conclusion Based on our results from our
experiments, we have concluded that our organism is not alive.
We were unable to test whether our organism reproduced or not.
