Their experiences introduce them to the following concepts, skills, and attitudes. Concepts Plants need soil nutrients, light, and water. Plant growth is affected by the quantities of nutrients, light, and water available. Controlling variables enables the effect of each to be identified and studied. Flowering plants must be pollinated in order to produce seeds.
Bees are effective pollinators.
One seed has the potential to produce one plant. The number of seeds produced by a single plant is affected by such variables as nutrients, light, water, and the extent of pollination. The orientation of a plant's growth is affected by gravity and light. Skills Planting and caring for plants. Predicting how changing one variable might affect the outcome of an experiment.
