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!!!!
