#conclusion improvements: next time i would use a more reliable way of measuring my data and use a darker room to make it more controlled.
#safety *not for this lab bc working with safe plants* Wear a lab coat at all times with goggles with your hair tied away if it is long.
#method #8 once you have finished collecting data for all of your concentrations make sure you have all of your graphs from the logger pro.
#method #7 Following the #5 instructions for all of the CO2 concentrations: 2g, 3g, 4g, 5g.
#method #6 finished: wash off elodea and refill beaker with water in preparation for the next concentration.
#method #5 continue doing this for 2 minutes and stop the program, save your data on your computer where you can access it again later.
#method #5 simultaneously add the O2 to the water and start the logger pro on your computer while stirring the rod in the solution.
#method #5 taking your first weighing boat (1 gram) and your beaker with 100 ml of water with the 20 cm elodea it it, 30 cm from the light.
#method #4 now pre measure all of the CO2 in 5 different weighing boats using the scale; 1g, 2g, 3g, 4g, 5g (grams).
#method this is what your experiment should look like when it is all set up, Almost there only a few steps left.
#method #3 Set up the logger pro program on your computer, plug in the O2 probe, make sure to test it before you start to make sure works.
#method #2 make sure to mark the 30 cm with a piece of tape so all of your trials are from the same distance from the light source.
#method #2 Plug in your 60 Watt light and tape it onto a stable surface, using your ruler measure out 30 cm from the base of the light.
#equipment continued: logger pro program, tape, ruler, water.
