Resources | Cup with lid Compass Marker Straws Masking tape Cardboard Scissors |
Instructions | Make the base: Take a cup with a lid. Label the 4 cardinal
directions on the lid (NESW). Insert one straw, and cover the top end of
the straw with a piece of masking tape. Make the top: Take a
second straw – cut slits in each end, and insert a cardstock flag in one
end and an arrow in the other. Balance that straw on your finger to
find the center of gravity. Push a pin through that point, then through
the tape on top of the straw. Make sure it spins freely.
To use: Fill the cup with water, then put this outside in the wind, with the letter N on the cup in the north. |
