Grow A CD Garden

After finishing the Hovercraft and Friction experiment, you will be left with an empty CD case.

Here is an upcycling idea.

The empty CD box can be used in this gardening project.

Grow a little indoor greenhouse full of grass in you kitchen.

Like most plants, grass needs water, soil, air and sunlight to grow.

In order to absorb water and nutrients in the soil, grass roots grow down into the earth. 

If you carefully examine the soil everyday, you will see that the radicle (primary root) is the first thing to emerge from the embryo during germination.
