Supplies
Needed:
The experiment is designed for teams of 2. Each team needs this
a gear set. There are plenty of supplies in one box so multiple
teams could share a set.
Discussion:
Start the session with a general discussion on gears. Have the girls
try turning one gear when it is connected to a second. Which way
does each turn? What if you put a chain of gears together, in what
direction does each of them turn?
Try using different sizes of gears. Which gear (large, medium or
small) spins the fastest? How many times around does a small gear
go when a large gear turns just once?
Allow time for the girls to freely explore the equipment. Included
in the kit are two different booklets. They have suggested beginning
and advanced building plans. For girls who want to do more, give
them one of these booklets and let them loose. |
