A seesaw is an easy example of this simple machine that helps lift a load.

Lever

100

Civil engineers design this so cars and people can cross over a river or road.

A bridge

100

Software engineers write these step-by-step instructions that tell a computer what to do.

Code/Program

100

Aerospace engineers design these flying machines with wings that carry people through the sky

Airplanes

100

Biomedical engineers build tools to help keep this healthy — it's your whole self, with a heart, bones, and brain.

The Human Body

200

These toothed wheels lock together and spin to move a bike's chain or a machine.

Gears

200

Civil engineers design these very tall buildings that reach high into the sky

Skyscrapers
200

A mistake or error in a computer program is called this.

A bug

200

Aerospace engineers build these to blast off and fly into space.

Rockets

200

This hard covering that a doctor puts on your arm helps a broken bone heal.

A cast

300

This is the part of a car that burns fuel to make power and move it forward.

The Engine

300

This three-sided shape is used in bridges and towers because it is so strong.

Triangle

300

Computers store everything using just these two digits

0 and 1/Binary

300

This force pulls a rocket back toward Earth, so it must push hard to reach space.

Gravity

300

A biomedical engineer can design an artificial one of these to replace a missing arm or leg.

A prosthetic / Artificial limb 
400

This force slows down moving parts when they rub together, so engineers add oil or grease to reduce it.

Friction

400

This strong part of a building, often underground, holds up all of its weight.

The foundation

400

A step-by-step set of exact instructions a computer follows in order is called this.

An algorithm

400

This machine orbits high above Earth and helps with TV, phones, and GPS maps.

A satellite 

400

Biomedical engineers design machines to help this organ, which pumps blood in your chest.

The Heart

500

This is the scientific word for a twisting or turning force like when you use a wrench to turn a bolt.

Torque

500

A bridge that hangs from tall towers and huge steel cables like the Golden Gate bridge is called what type of bridge?

Suspension bridge

500

Each 0 or 1 is called a "bit." What do we call a group of 8 bits?

A byte

500

This is the name for the powerful forward push made by a rocket or jet engine that lifts it off the ground.

Thrust

500

This small electronic device is placed in the chest and uses tiny electric pulses to keep a heart beating steadily.

A pacemaker
