Competition in Ecosystems Activity for Kids

Plant Resource Competition DIY

  • Duration: 4 weeks of growing
  • Difficulty: Easy
  • Cost: $0 to $10

Grow seeds to make plants compete for resources!

Material List

  • 1Bag of potting soil
  • 3Small pots
  • 1Pack of seeds
  • 1Cup of Water


  • 1Fill the three pots with an equal amount of soil.
  • 2Make a hole in the center of the soil.
  • 3In the first pot, add 3 seeds into the hole.
  • 4In the second pot, add 20 seeds into the hole.
  • 5In the third pot, add 100 seeds into the hole.
  • 6Lightly cover the seeds with soil.
  • 7Add ½ cup of water daily to each and observe over 4 weeks.

How It Works

Living things compete for resources to survive. This also includes plants. The pot with 3 seeds grew the best because there was less competition for resources, like water and light. That is also why the pot with 100 seeds grew the worst.
