Vocabulary
Electromagnetism is the science of how electricity and magnets work together.
When electricity flows through a wire, it can make a magnet. And magnets can also make
electricity move.
Simulation means making something look or act like the real thing, but it’s not actually real. It’s
like a pretend model that helps us understand or practice.
Prototype is the first model of something new that we want to make. It’s like a practice version
that helps us test our ideas before making the real thing.
Microchip is a tiny computer part that helps machines think and work. Even though it’s very
small, it can do many jobs very fast.
Hydraulics is the use of water or liquid to move things. When we push liquid through pipes or
tubes, it can make machines lift, push, or pull heavy things.
Sustainable means using things in a way that is good for the Earth and makes sure we don’t
run out of them. It’s about taking care of nature so future kids can use it too.
Thermodynamics is the science of heat and energy—how they move and change.
Biofuel is a type of fuel made from plants, food, or waste instead of from oil or gas. It gives us
energy in a way that can be better for the Earth.
CAD means Computer-Aided Design. It’s when we use a computer to draw and design
things instead of just using paper and pencil.
Optimize means making something work the best way possible. It’s about finding the
easiest, fastest, or smartest way to do something.
A robotic arm is a machine that can move and pick up things just like a human arm. It is
controlled by a computer or a person.
Aerodynamics is the science of how air moves around things and how it helps them fly or
move smoothly.
CFD stands for Computational Fluid Dynamics. It’s a way to use computers to see how air
or water moves around things.

FEA stands for Finite Element Analysis. It’s a way to test if things are strong and safe using
computers before we build them.
Unit testing means checking small parts of a thing to make sure they work correctly before
using the whole thing.
Integrate software modules means putting small parts of a program together so they all
work as one big program. If you make a video game, you put the sounds, pictures, and controls
together so it works.
System testing means checking the whole program or machine to make sure everything
works together properly. Checking a video game to see if the pictures, sounds, and controls
all work.
Firmware is a special kind of software that tells a device how to work. It’s usually inside the
machine and helps it do its job.
Embedded system is a tiny computer inside a device that helps it do its job. It’s hidden
inside, so you usually don’t see it. A washing machine has an embedded system to know when
to wash and stop.
Remediation plan is a plan to fix or improve something that isn’t working well. If a plant
isn’t growing well, a remediation plan could be watering it more or giving it sunlight.
