Potato Experiment

By, Brady, Kaila, Cord, Kit, and Lindsay

Creating our own experiment

You teacher will give you a slice of potato. Predict what percentage of the potato's mass is water. Then come up with an experiment to test your prediction. For materials, you will be given a hairdryer and a scale. Obtain your teachers approval before carrying out your plan.

Procedure

We started out by weighing the potato. We thought about what percentage of the potato was water, and guessed 45%. We then blow-dried the potato to get out all the water. This didn't work. So we used the microwave instead. After that we weighed the potato again. This allowed us to determine a potato is about 77% water.

How this relates to our reading.

A potato is a living thing. It has the four basic needs of living things. We were able to tell from this data that the potato is effectively the tank for the potato plant. It is also the collector of water, we believe. It uses this water to make food, and keep itself in homeostasis (more on that soon).

4 needs of living things

The first need for an organism is food. Food is produced in many ways (see above graph). The second need is water. All living things need water to survive. All organisms need water and food to reproduce. The third thing is living space. All organisms need living space for protection. But, there is limited amount of space so organisms have to fight for space. The last thing is homeostasis. Homeostasis keeps internal conditions right for cells to function.
