It's for our Investigatory Project. the experiment is good for 2-3 months. This is our experiment. We will use 4 Lucky Bamboo plants (4 setups). In setup A, we will pour salt solution, B: sugar solution, C: Isopropyl Alcohol, D: Tap water. One of our dependent variables is how long the stem will grow in a given period of time. So, like, how often should we record? weekly? every 2 weeks? how long does it take for the stem to grow 1 inch?
How often should we record results?
Every 10 days.
