Week 3: Plant Energy

 This week, the questions we were investigating were:

Where do plants get their food? 

Where do plants get their energy?

To investigate those questions, we discussed photosynthesis and how plants get their energy and make their food. We discovered that the plants are made up of sugars, and the photosynthesis process makes up the sugars along with releasing oxygen. 

We wanted to prove that sunlight was needed for plants to take in CO2, so we created an experiment. We have 2 of the same kind of plants and put a solution in it that tested the PH balance. It was green when we put the plants in. We put one in the sunlight and one in a dark cabinet to see which one took in more CO2. 

We found that they both ended up being a similar color, but we think the reason for that is because of timing of the experiment. If we took more than 20 minutes on it, I believe it would've showed more of a change. I have attached pictures of our experiment, the capsule to the left is the one that was exposed to sunlight.
