States of Matter
This state of matter has a definite shape and a definite volume.
What is a solid?
This is the amount of matter in an object, often measured using a balance scale.
What is mass?
This is the form of energy that we can hear, caused by vibrations.
What is sound energy?
This temperature scale is most commonly used in the United States to measure weather.
What is Fahrenheit?
This happens to liquid water when it is cooled down to 32°F (0°C).
What is freezing (or turning to ice)?
This state of matter takes the shape of its container but has a fixed volume.
What is a liquid?
This is the amount of space an object takes up.
What is volume?
This type of energy is stored in things like food, batteries, and fuel.
What is chemical energy?
This is the ultimate, natural source of light and heat energy for Earth.
What is the Sun?
When you mix sand and water together, you create this kind of combination, which can be easily separated.
What is a mixture?
This state of matter has no definite shape and spreads out to fill any container.
What is a gas?
This property describes whether an object will sink or float in water.
What is buoyancy (or density)?
This is the energy of motion, such as a rolling ball or a running child.
What is mechanical (or kinetic) energy?
This word describes what happens when light bounces off a shiny surface like a mirror.
What is reflection?
This is a special type of mixture where one substance dissolves completely into another, like salt in water.
What is a solution?
Water vapor in the air turning back into liquid water droplets to form clouds is an example of this process.
What is condensation?
This property describes how easily a material can be scratched, often tested using pennies or minerals.
What is hardness?
This form of energy flows through wires to power appliances, lights, and computers.
What is electrical energy?
This is what happens when light bends as it passes through a lens or water.
What is refraction?
This process occurs when liquid water is heated and turns into water vapor (a gas).
What is evaporation?
This invisible gas is formed when liquid water evaporates or boils.
What is water vapor?
This physical property determines whether an object is attracted to iron or steel.
What is magnetism?
This is the basic, scientific definition of what energy actually is.
What is the ability to do work (or cause change)?
Heat energy always turns into this after a while without heat.
What is from a warmer object to a cooler object?
Baking a cake or burning a piece of wood are examples of this type of change, where a brand-new substance is made.
What is a chemical change?
