Growing with Tu BiShvat: 🌱 Grass Seed “Mr. Potato Head” Plant Experiment in Our ECC Class
This week, our Saplings (ages 3–4) explored plant growth and early science concepts through a hands-on Grass Seed “Mr. Potato Head” project inspired by the spirit of Tu BiShvat and our ongoing nature studies.
Through this interactive activity, the children observed germination and plant growth in real time while learning about the basic needs of living things — water, sunlight, and nutrients. This simple but powerful experiment introduced foundational biology concepts in a developmentally appropriate and engaging way.
🌿 What We Used
One potato per child
Cotton balls
Water
Grass seed
Metal scoop (for hollowing the potatoes)
Plastic cups (to help the potatoes stand upright)
Tray for outdoor sunlight exposure
✂️ What We Did
First, we carefully cut off the top of each potato and scooped out the inside to create a hollow space. Each child had their own potato to transform.
Next, the students dipped cotton balls in water and filled the hollowed potato with the moist cotton. The moisture would help the grass seeds begin the germination process.
Then came the most exciting step: sprinkling grass seed over the cotton, making sure the surface was fully covered. Once assembled, we placed each potato into a plastic cup to stand upright and moved them to a sunny outdoor location.
Over the next two weeks, the children will monitor and chart the growth of their “hair,” observing how sunlight and daily watering help the grass sprout and grow.
🌱 Skills We Practiced
This activity supported key areas of early childhood development, including:
Fine-motor skills (scooping, placing cotton, sprinkling seeds)
Scientific observation and early biology concepts
Understanding plant life cycles and germination
Patience and long-term project tracking
Cause-and-effect learning
Responsibility through daily watering and care
🧠 Science in Action
As the days pass, the Saplings are eagerly checking their potato heads for signs of growth. Watching the first green sprouts emerge reinforces important scientific concepts and builds excitement around nature-based learning.
By engaging in hands-on plant experiments like this one, our students experience science not just as a concept, but as something they can see, nurture, and understand.
🌞 Reflections
The Saplings were enthusiastic from start to finish — carefully assembling their potato heads and eagerly anticipating the grass growth over the coming weeks.
Projects like this blend Jewish values of caring for the earth with foundational science learning. Through curiosity, observation, and responsibility, our children are growing right alongside their grass seed creations.
