A seesaw is an easy example of this simple machine that helps lift a load.
Lever
Civil engineers design this so cars and people can cross over a river or road.
A bridge
Software engineers write these step-by-step instructions that tell a computer what to do.
Code/Program
Aerospace engineers design these flying machines with wings that carry people through the sky
Airplanes
Biomedical engineers build tools to help keep this healthy — it's your whole self, with a heart, bones, and brain.
The Human Body
These toothed wheels lock together and spin to move a bike's chain or a machine.
Gears
Civil engineers design these very tall buildings that reach high into the sky
A mistake or error in a computer program is called this.
A bug
Aerospace engineers build these to blast off and fly into space.
Rockets
This hard covering that a doctor puts on your arm helps a broken bone heal.
A cast
This is the part of a car that burns fuel to make power and move it forward.
The Engine
This three-sided shape is used in bridges and towers because it is so strong.
Triangle
Computers store everything using just these two digits
0 and 1/Binary
This force pulls a rocket back toward Earth, so it must push hard to reach space.
Gravity
A biomedical engineer can design an artificial one of these to replace a missing arm or leg.
This force slows down moving parts when they rub together, so engineers add oil or grease to reduce it.
Friction
This strong part of a building, often underground, holds up all of its weight.
The foundation
A step-by-step set of exact instructions a computer follows in order is called this.
An algorithm
This machine orbits high above Earth and helps with TV, phones, and GPS maps.
A satellite
Biomedical engineers design machines to help this organ, which pumps blood in your chest.
The Heart
This is the scientific word for a twisting or turning force like when you use a wrench to turn a bolt.
Torque
A bridge that hangs from tall towers and huge steel cables like the Golden Gate bridge is called what type of bridge?
Suspension bridge
Each 0 or 1 is called a "bit." What do we call a group of 8 bits?
A byte
This is the name for the powerful forward push made by a rocket or jet engine that lifts it off the ground.
Thrust
This small electronic device is placed in the chest and uses tiny electric pulses to keep a heart beating steadily.
A pacemaker
