Questions We Tested

Does our unknown have cells? Does our unknown adapt? Can our unknown store/release energy? Does our unknown develop?

Page 3: Is It Alive?

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.

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

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.
