Energy and Nutrient Cycling The Big Idea: "Is More Food Better?" (145 K PDF file) Because of their ease of growth and short life cycle (seed to seed in 35 days) Fast Plants® are an organism suitable for many kinds of home and classroom scientific investigations. They are particularly interesting because, like humans, they exhibit considerable variation in many observable characteristics. Fast Plants® are useful for experiments investigating the effects of environment (light, nutrition, etc.) on variation in growth, development and reproduction. This activity addresses the effect of nutrient on growth and reproduction. Specifically you will investigate how much fertilizer (nutrient or plant food) is best for the production of a crop of Fast Plants® seed. This is the same question that farmers ask every time they plant a crop. Exploring Photosynthesis with Fast Plants (88 K PDF file) This activity offers an engaging laboratory investigation which can be used to explore and gather evidence for the products of photosynthesis (and cellular respiration). It uses low cost, simple materials and seed leaves (cotyledons) from 3 or 4 day old Fast Plants. Producer Power! (168 K PDF file) An article written for children, this reading explains the role of plants as producers. It is written at a grade 4-5 reading level, and it is a good supplement to the evidence that students can observe and record through experimentation with photosynthesis.
