Oh the joys of science fair projects. Rian has done her share, now Jarom is in full swing. Luckily, this was a pretty easy, yet fun experiment. He worked on Transpiration in plants. He used celery and carnations to demonstration the flow of water with colored water. It was pretty cool.
He had two experiments to prove his hypothesis. Experiment A was water evaporating out of stomata on the leaves, and Experiement B was the pathway water took up the plants.
Experiment A
Not too many green leafy plants around, but we tried this one from a bush out front. We had to let it acclimate for a few hours before starting... Putting one bag of leaves in darkness (cupboard) and one in sunlight (window sill) you see results of evaporation from the leaves stomata from sunlight.
Experiement B
Celery and carnations in their red and blue water in sunlight...results turned out ok, but with colder temps outside and less sun peaking out of the clouds, I'm sure things could have been more prominent. Carnations were cool with the blue stripes...red needed more time or sunshine/warmth to really show anything.
Celery did well. You could see where the water exited the stomata (pores) and left the color behind, making clusters of color. Cutting open the celery you could see the pathway up the stalks.
Although these projects can be a pain to complete because they have to be a certain way (we are now professionals at this) it was neat to see it all come together. Nice to have it checked off the list...Good Job Jay.
