We wanted to determine what a plant needs to grow, so we carried out several experiments! When conducting an experiment, we learned to keep everything the same, and just change ONE thing. Here are our results!
One plant was placed in light, and one stayed in a dark cupboard. Plants sure need sunshine! |

Do plants really need water? We had two identical plants and put them both in the light. One was watered and the other one was wasn't. Seems to us that water is very important!

We all thought the plants that didn't get water or light ended up looking like purple Minions ... right?
Do plants need dirt to grow? We planted grass seed in various things, including sand, dirt, gravel, and rice. We found that although the grass grew in the soil and sand both very well, the grass in the sandy cup eventually died. Surprisingly, we noticed a few hardy sprouts in the rice, but we tossed it once it got too stinky. Verdict? Soil is best!
We explored how plants transport water, and did an experiment with water. Celery was placed in coloured water and the leaves quickly turned red or blue (within a few hours!).
We also enjoyed growing bean seeds. We planted seeds in plastic cups by tucking the seed against the side of the cup using wet paper towels. This allowed us to watch the plant as it grew, kind of like a little window. Daily watering was key!
We have learned oodles about plants and what they need to grow! Unfortunately, Mrs. Beliveau still seems to be more of a hospice for plants until they go home to meet Jesus.
