After School Week 4

Conductor and Insulator

What career involves working with power plants, computers, and other electrical
devices? Electrical Engineers of course! This week the girls had to work together in
groups and complete an electrical circuit in order to get a light bulb to turn on. Their
main source of power was a 9V Battery along with alligator clips. They tested various
objects such as a penny, a nail, a pencil, a strip of aluminum foil, a large craft stick, a
rubber band, a cotton ball, a pipe cleaner, and a plastic spoon.

After School 'To Go' Weeks 1 and 2

Week 1

What are levers? Well, levers make work easier by converting a small amount of effort into a lot of force
or by converting a little movement into a large movement. And who doesn't want to get more done with
less effort? Hammers, brooms, golf clubs, and baseball bats are just some examples of levers but if you
think about it they’re all around us.

For this activity, the girls learned about levers and were challenged to create their own. They worked
through the engineering design process to build a catapult that would launch a ping pong ball high
enough for someone else to catch it.

After School Week 3

Solubility in Packing Material

The careers of the week are Manufacturing and Environmental Engineering! The girls tested the solubility of packaging materials such as a biodegradable packing pellet, a piece of freshly popped corn, a piece of newspaper, and a styrofoam packing peanut. They used warm water as the solvent and mixed in the solutes in four individual cups.

After School Week 2

Density Shapes

Things are building up in week two of Girlstart’s After School programs. The girls started off
guessing what foil objects would float depending on density and buoyancy. They studied a
regular coke can and a diet coke can, and concluded that, “The regular coke does not float
because it has more sugar.”
