A.1 States of Matter
The state in which a substance expands to occupy the volume and shape of its container. The particles are fast moving and can spread apart from each other.
Gas
Information that explains or supports a claim.
Evidence
Anything that has mass and takes up space.
Matter
A step-by-step way to solve problems.
Design Process
The property of a material to stretch and return to its original shape.
The state in which a substance adapts to the shape of its container, and mostly maintains its volume. The particles are touching but they can move past each other.
Liquid
A substance that contains two or more substances which are not chemically combined.
Mixture
A very small piece of matter. All matter is made of particles too small to be seen.
Particle
A person who designs, constructs, and uses machines.
Mechanical Engineer
The property of a material to curve without breaking.
Bend Strength
The measure of the amount of matter in an object.
Mass
A characteristic of a material.
Property
Matter that has specific components and properties.
Substance
A request from a manufacturer to return a product after the discovery of safety issues or product defects that might harm the consumer.
Recall
The property of a material to withstand repeated weight or force before wearing out.
Fatigue Strength
A characteristic of a material.
Property
A process that scientists use to explore observations and answer questions.
Scientific Inquiry Proceess
The matter from which a thing can be made.
Material
The property of a material to be stretched or pulled without breaking.
Tensile Strength
A limitation or a restriction. Constraints can include limits on time, materials, and size.
Constraint
The state in which a substance maintains a fixed volume and shape. The particles are packed closely together.
Solid
The principle that matter can neither be made nor destroyed; rather, it can only be transformed or transferred from one form to another.
Conservation of Mass
A process in which one or more substances undergo a change to become a different substance altogether.
Chemical Reaction
A standardized and documented process for performing an experiment or conducting an evaluation.
Testing Procedure
Guidelines or rules used to make a decision about something.
