In Science, we are learning about plants.  We have learned about what plants need.  Plants need water, air, sunlight, soil, and space.  We have also learned the parts of a plant and their function.  Roots bring water to the stem and hold the plant in place.  Leaves absorb the energy from the sunlight and make food for the plant.  The stem brings water to the leaves and holds up the flower.  The flower produces the seed.  The seeds make new plants.  We are doing an experiment to find out what plants need to grow best.  We planted grass seeds in cups.  One cup has sun and water, one cup has sun and no water, and one cup has water but no sun.  The cup with no sunlight has grass growing but the grass is yellow.  We know that plants need sunlight to make chlorophyll.

Experiment to prove the stem brings water to the leaves.
