Do earthworms enhance sweet corn growth?
I'm moving on to regional science fair because I received gold as a medal. Have ten corn plants in all, five with earthworms, five without. Have three cone shaped lamps to give light. Put three earthworms in each pot of the five group. Give each plant 60mL a day. Worked for me and I hope it will for you too.
grass plants are very good
can plant better grow
it isn't good, it would destroy the plant/animal.
nothing
Here are some links to try out.

test plants with different light sources
Good organic soil is best for most plants. But some plants prefer sand or rocky soil. Do some research to see what your plants prefer.
Delawares plant life is complicated. It has some good soil and some bad.So it depends on what you are growing.
I always loved coming up with science fair projects with my children while they were in elementary school. A good one for a third grader are playing two different kinds of music to two different plants to see which one grows faster and making a daily log regarding the plant and the music.
