Description: This dramatic time lapse shows corn kernels sprouting over time. Each of the kernels represents a new corn plant and so corn cobs represent a wonderful organism for studying genetics. In elementary this phenomenon can be used to show what plants need to survive. In secondary students can investigate specific crosses, analyze patterns in the offspring, and could even study transposons "jumping genes".

Abstract

An agricultural experiment is usually associated with a scientific method for testing certain agricultural phenomena. A central point in the work of Paul Richards is that experimentation is at the heart of agricultural practice. The reason why agricultural experiments are something different for farmers and agronomists is not their capacity to experiment as such but the embedding of experiments in a specific ecological, material and institutional environment. Using a historical perspective, changes are examined in the organization of agricultural experiments focusing on the Netherlands and colonial Indonesia during the first half of the 20th century and the international agricultural research institutes for the period thereafter. The results show a gradual shift in the role of experiments in the connection between science and practice. Initially, the link was considered to be established through various forms of experiments, rooted in an integrated social and technical understanding of agronomy. Gradually, this turned into a connection primarily established through various forms of communication. Recent work of Richards incorporates ideas that address key issues emerging from the history of agricultural experiments, dealing with an integrated social and technical understanding of agriculture.

Plan and conduct an investigation to determine if plants need sunlight and water to grow.

This phenomena is based on how corn needs light and water to grow. It describes the parts in which help them survive and grow. There is something inside a seed that needs water to start growing structures that will become the plant.

Something (such as an interesting fact or event) that can be observed and studied and that typically is unusual or difficult to understand or explain fully.
My phenomena on corn is all about how and why it grows. It starts as a seed and from sunlight, water, and chemicals, it grows into a plant! So cool! We can learn so much about corn and the process it goes though to become food.
