Growing Grass: A Fun and Easy Earth Day Themed Preschool Science Activity

We have grown grass as a preschool science activity for years now. Grass is easy and fun to grow, making it the perfect preschooler science activity. The year I took these photos (2009), the grass even survived three-year-old Emma and one-year-old Johnny dumping out the cups of newly-planted grass seeds and then throwing everything back in topsy-turvy.

Materials Needed for Growing Grass

• Cup (clear ones are nice since you can see some of the roots) OR Terra Cotta pots decorated by the kids
• Soil
• Grass seeds
• Water

How to Grow Grass at Home

1. Fill cup with soil, leaving at least 1 inch of clearance at the top.
2. Add a thin layer of grass seeds.
3. Cover the grass seeds with a small amount of soil.
4. Water.
5. Place in a sunny area.
6. Wait for seeds to grow.

Grass is the perfect plant for preschool botany, because it is incredibly hardy. This year is the perfect illustration of this hardiness, because Emma’s cup of grass seed was dumped all over the floor within an hour of being planted.

I swept up the dirt and dumped it back into its cup. I thought it wouldn’t grow, but I was wrong. Here is the poor destroyed grass plant surviving five days later:

And thriving two weeks later. You have to look twice to tell which cup was dumped out and which one was left alone!

Kids love giving their grass plants “haircuts” – perfect for practicing scissor skills.
