Die-cut sponge and use for growing plants.
Conduct a simple scientific investigation, in which students identify and explain whether plants can grow without soil. Observe how air, water, nutrients, sunlight and space are basic needs in the plant life cycle. Consider growing plants with and without soil to compare growth. Challenge students to grow plants in different media for further study.
Follow the scientific method to investigate results of growing plants in a medium other than soil.
Supplies Used: Alfalfa Seed, Pop-Up Sponge, Eyedropper, Paper Towels, Scissors
The teacher will die-cut the materials for student use prior to the lesson.
- Die-cut the Puffy Star to create the planter.
- Moisten the sponge and watch it expand.
- Sprinkle alfalfa seeds on top of moistened sponge.
- Water daily with eyedropper. Watch your plants grow! (see Main Photo)
