Week of May 26

This week I worked with me new topic. I have mostly been working on a way to test weather change in net gas exchange is due to an impact of DC Current on the light dependent or to the light independent reactions. I have been using algae to try and test this. Algae is a simple photosenthetic organism, that is unlikely harmed by electricity. This makes it an optimal organism to test With. What i am attempting to do is create two chambers with algae and O2 sensors. One with an electric current and one withought. Both will go through a period of light and dark while O2 levels are recorded. Then I will compare differences between the two chambers during both light and dark periods, and see which (dark or light) produces the greatest variant vroom the control. This is the first step in isolating the cause of the change in gas exchange caused by an electric current.

Week of may 19

the past 2 weeks we have begun our genious hour and taken the ap exam. Phew, finally over! After the exam, I had started looking I to a potential experiment involving the minipulation of water potential to get water to flow uphill. I was hoping to design a model for a potential type of water pump, that would be eapecially helpful to ski resorts, but it ended up looking to be too difficult a task to complete over the course of the next few weeks. This week I decided to move to a new experiment, shocking plants more or less. Earlier in the year we did a lab on environmental changes that effect photosynthesis. Our group applied an electric DC current to it. I would like to go back to this, because the current actually stimulated rate of gas exchange and therefore rate of photosynthesis. It is unclear why this happened and I hope to examine this by looking more closely at photosynthesis and isolating what in particular is being effected.
