The following experiment is a fun and easy way to see the effects of germination and the quick growth of grass
These are the materials needed to make your own Potato Head with growing hair:
-Large potato

-Cotton balls
-Small bowl or shallow dish
-Any quick growing grass seed
-Paring knife
-Spoon or melon baller
-Items that will stick into the potato to create a face
(e.g., thumb tacks, rice grains, cloves)
Methods:
Cut the top and bottom off of a large potato.
Ask an adult for help!
Use
a spoon or a melon baller to scoop out the top of the
potato (melon baller works best).
Put
a few cotton balls in the hollowed out portion of the
potato.

Make
a face on your potato using your imagination and what you
have around like, thumb tacks, rubber bands… (we
glued google eyes on thumb tacks for the
eyes).
Use
the other end of the potato to sit in a shallow dish of
water.
Sprinkle some grass seeds on the cotton balls and keep
watered. Place dish near a window that gets some sun but
not in direct sunlight (you may want to mist the top with
water to keep in moist).
In a few days your potato will have a head of
hair!!!!
