Observing physical properties
Anything that takes up space and has mass.
What is matter?
The forms in which matter can exist, specifically solid, liquid, or gas.
What are states of matter?
A change from a solid to a liquid caused by adding heat.
What is melting?
A substance used to make a product.
What is a material?
How a material feels to the touch, such as smooth, rough, bumpy, or grainy.
What is texture?
A characteristic of matter that is measurable, testable, or observable.
What is a physical property?
An object with a set volume and shape.
What is a solid?
A change from a liquid to a solid caused by removing heat.
What is freezing?
o mix two or more things together to form a new object or substance.
What is to combine?
How much space matter takes up.
What is volume?
The amount of matter in an object or a substance.
What is mass?
An object with a set volume but no set shape, filling the bottom of its container first.
What is a liquid?
Water in a gas state.
What is water vapor?
To make changes or improvements to an object or substance.
What is to modify?
he measure of heat energy in matter; adding it causes solids to melt and liquids to turn into gas.
What is thermal energy?
When an object goes below the surface of a liquid versus staying above the surface.
What is sink or float?
An object with no set volume and no set shape that expands to fill its container.
What is a gas?
A change in the shape or appearance of matter that does not change what matter is made of.
What is a physical change?
A model of a design built by engineers to test an idea.
What is a prototype?
The process when a liquid is heated and changes into a gas.
What is evaporation?
A measure of thermal energy.
A force that repels or attracts certain materials across a distance.
What is temperature?
What is magnetism?
To arrange or order things in a particular way based on shared characteristics.
What is to classify?
A change in state when warm air hits a cooler area and causes a gas to turn into a liquid.
What is condensation?
A limitation or boundary in the design process, such as budget, time, or available supplies.
What is a constraint?
A physical property describing a material's tendency to fracture, break, or crumble.
What is brittleness?
