There are some words used in Strange Science that might be new to your kids. We define them in our videos, but here’s a list of them so that you can more easily participate in conversations with your kid about what they’re learning.

Molecules - Tiny particles made up of atoms that form elements and compounds. They’re the smallest components that makes up matter - people, animals, objects, and everything you see!

Mass - The amount of matter in an object.

Surface Area - The measurement of the total amount of area (space) an object occupies.

Reverberation - This refers to sound waves that go off in different directions and bounce off of other surfaces before reaching your ears.

Conductivity - How easily heat can move through an object.

Conductors - Objects through which heat or electricity travels quickly and easily.

Insulators - Objects through which heat or electricity travels slowly and with more difficulty.

Gravity - The force that attracts an object to the center of the earth or to another object with mass. This is what keeps your feet on the ground and prevents you from floating off into space!

Potential Energy - The initial input of energy, or the energy of height. We measure this when an object is set in a certain position.

Kinetic Energy - The energy of speed or motion. We measure this when an object is moving.

Air resistance - An upward force that goes in the opposite direction of the force of gravity.

Aerodynamics - The study of how air moves and interacts with solid objects that move through and around it.

Circuit - The path through which electricity is generated. Electric current leaves the power source (e.g. a battery), travels through conductive material to enter the device you’re powering, and flows back to the power source.
