Plant experiments and an inventory of what we know

Grade(s): 2nd/6th

Objective: To use the scientific method to conduct two experiments about plants and to review what we've learned

Procedure:
Experiment 1--Fill a mason jar with lettuce and water, flip the jar over into a pie pan, leave the jar in the sun for at least a day, observe what happens
Experiment 2--Cut celery and place it in a cup, partially fill the cup with food coloring and water, leave the celery in the colored water for at least a day, observe what happens

What we know about plants (an inventory by M and M and K):

-There’s a species of plants called geraniums.

-Plants need water.

-Plants have rectangular cells, with cell walls.

-Plants get their energy from the sun.  (Plants eat sun!)

-Plants photosynthesize

-Plants are green because of their chlorophyll.

-Plants turn yellow, red, and orange in the fall because they stop photosynthesizing because there are shorter days and less sun.

-Plants need nutrients from the soil

-They grow from seeds that they make and spread.

-Some plants have both female and male parts

(When we finished our inventory we printed all our facts in green and taped them around our library garden)
