What you need:
- Sprouting potato
- Shoebox with lid
- Cardboard
- Scissors
- Glue or sellotape
How to:
- Cut two cardboard pieces the height and width of the
shoebox.
- Cut a 2 centimetre diameter hole in each piece.
- Cut a 2 centimetre diameter hole in one end of the
shoebox.
- Glue or sellotape the cardboard pieces into the shoebox.
- Put a sprouting potato in the opposite end of the shoebox to
the hole.
- Put the lid back on and leave the shoebox in a sunny place,
with the hole facing the light.
Plants need light to grow. What do you think the potato will do
as it tries to find the light? Will it complete the obstacle
course? Check the potato every 2-3 days to see what's
happening.
