| Explore | Milkweed we are growing in class turned purple and growth was stunted under a red/blue/white LED light while those grown under a full spectrum light grew normally. |
|---|---|
| Research Question | If the color of light affected the milkweed plant will it also affect its seeds? |
| Predictions | Our predictions are that the milkweed will change depending on the color of light. For example, the milkweed may have trouble sprouting out of the seed. Other thoughts are that the seeds could get bigger or break apart in the process. |
| Experimental Design | Place ten milkweed seeds on a piece of moist paper towel in a covered petri dish. Put the petri dish under full spectrum LED grow lights. Do the same procedure except put the experimental group under the Red/Blue/White grow lights. Control: seeds under white light Experimental group: seeds under RBW LED light |
| Conclusion | After observing the seeds from our control and experimental groups. The seeds are pretty much identical to each other. The only noticeable difference between the experimental and control group is that the experimental group had condensation. The control was completely dry. The amount of seeds also stayed the same, implying that none of the seeds split as well. However, there was not enough time to really get good observations and differences. |
