Hi JC, A nice experiment to show kids it is the effect of sun light on the etiolation and de-etiolation of plants.
You can easily germinate beans in a light and a dark environment to show that the one growing in darkness will be longer and (usually) paler that the one in light. A more complex way of doing this experiment is to use containers with a glass (or any other clear material) and show what happens to the plant when, after germination, and before reaching the surface, sunlight reaches the sprout. the control in this case will be another container with a clear side but keeping that side covered with tin foil and just remove it to see the plant. Hope that works On Fri, Oct 5, 2012 at 6:08 AM, VOLTOLINI <[email protected]> wrote: > Dear friends, > > I am preparing a course about teaching ecology for kids.
