Dear Parents and Supervising Adults!

Children want to explore,

understand, and create new things.

They want to try things and do them by themselves.

Spinning Wheel ............................................... 9

They want to learn! They can do all of this with Gigo experiment kits. With every single experiment, they grow smarter and more knowledgeable.

Meet the Omega Family!

Ty and Karlie Omega are siblings.

They live in a small city called Makersville. Ty and Karlie’s dad is a writer. He writes science fiction stories. Their mom is a mechanical engineer. She designs big machines used in factories.

Ty loves figuring out how things work. Karlie loves building things.

They live in an awesome warehouse filled with tools, equipment, and building materials. There are always a number of projects going on in the warehouse.

Ty can’t wait to figure out how all the tools work, and Karlie is excited to see all the fun models she can build!

Now it’s time for Ty and Karlie to build their very own workbench where they can keep their own tools.

Yay!

Let’s go!

Gears are wheels with teeth that engage with each other to transmit motion. In other words, gears make things move!

When you rotate the large purple gear, which gears move faster: the large gears or the small gears?

Done!

Look closely!

When you turn one gear clockwise the gear next to it turns counterclockwise!

And vice-versa!

Gears can change the axis of rotation. This means, if you rotate a gear that is flat on the ground, it can rotate a gear that is on a wall.

Car engines use gears like this to drive the wheels and make the car go!

By stacking different-sized gears on the same axis, a gearbox can change the speed and torque — or rotational power — of motion.

Gearboxes are used in many mechanical devices to slow down electric motors, which spin very fast, while creating more output power.

A gearbox contains a gear train, which is a series of gears linked together.

Experiment by building different gearboxes. How fast — or how slow —can you make the gears go?
