Read Eric Carle's The Tiny Seed. What does a seed need to grow? Let's set up an experiment with radishes and find out! Radishes must be one of the easiest things to grow on the planet. Even a non-"green" thumb can't mess this up!
Plants have a few basic needs in order to grow -- light, water, air and good "soil". They also must have each of these in the proper amount! Too much water or rain will ruin the plant. Not enough and it won't grow. It is the same, with too much light (or darkness), improper airflow, etc. We are going to skip the soil in this experiment simply to observe the germination stage of radishes (where they begin to sprout roots). Together let's observe what happens in various tropisms -- circumstances that cause the plants to react a certain way -- in our case the varied environments.
Gather the following items and follow the instructions in the diagram below:
- Baby food jar
- Paper towels
- Plastic wrap
- Radish seeds

What did you learn from your observations about the various environments? Explain what the different types of environments are like. Which have more light? More water? Which one is the driest?
Finding the proper balance of all the ingredients (light, water, air and soil), is a must for any garden to grow. Now that you have learned try your hand at planting a small garden (or plant) being extra careful to keep things stable! Before long you can enjoy your own vegetables on your dinner table!
