Growing grass in recycled cardboard egg cartons is pretty easy and inexpensive to do. Plus the cartons are biodegradable.
- Soak the seeds overnight in water.
- Separate the egg container compartments if desired.
- Make a small hole in the bottoms of the egg containers.
- Have the students use a hand lens to observe the seeds.
- The kids may want to draw a smiley face on the outside of their egg container.
- Have the kids add soil to each egg container compartment.
- Have the kids use their fingers to poke a few holes in the top layer of soil and drop in a few seeds in each hole.
- Cover the seeds over.
- Put the containers on a tray to collect extra water.
- Put the seeds in a sunny spot and water daily (or as needed).
- Students should use the hand lens again to continue observing the seeds as they start to grow.
- As the grass grows, the kids may want to give their smiley face a "haircut" (the newly sprouted grass)!
Another idea for the recycled egg carton containers is to plant different seeds in each compartment. Have the kids observe all the seeds with a hand lens before planting. Have the kids label each compartment as they plant the seeds and compare the seeds as they grow.
