The Lowdown on Dirt is a science project that teaches kids about soil quality. When it comes to supporting plant life, not all dirt is equal.
What You'll Need:
- Garden soil
- Small flowerpots with saucers
- Bean seeds
- Tall stakes
- Pencil or pen
- Paper (graph paper optional)
How to get the Lowdown on Dirt:Step 1: Look in your yard for areas where plants grow poorly. Is the soil trampled and hard? Is the soil soft and loose where plants grow well? Look for sandy or heavy, clay-like soil.
Step 2: Gather samples of different soils and fill a flowerpot with each kind. Label your flowerpots: "Hard, baked soil near the sidewalk," "Loose, fluffy soil from the flower bed," etc.
Step 3: Water the pots, then plant two or three bean seeds in each. Put a stake in each pot for the beans to climb. Keep the pots moist (but not soggy) while the beans sprout.
Step 4: Notice which beans sprout first. Measure the height of the plants every few days until the beans flower. Keep a chart. Which soil was the best?
