Properties of Matter
Anything that has mass and takes up space is known as what?
Matter
This is the term for a plan or method people use to find and develop solutions to a problem
What is the Design Process
This term describes a quality, trait, or detail used to describe something.
What is a property?
These are the invisible particles of water found present in the air at all times.
What is water vapor?
This term is defined as information that helps answer a question, support a claim, or solve a problem.
What is evidence?
People can use _____________ to describe and identify matter.
properties
These are the two things engineers evaluate about past solutions, one dealing with good aspects and one with bad
What are positive properties and negative properties?
Ice turns into a liquid at this specific Fahrenheit temperature
What is 32°F?
Breathing onto a cold window pane causes water drops to form through this process.
What is condensation?
This property describes an object's ability to float in a liquid like water.
What is buoyancy?
The ability of a substance to dissolve is called ______________.
Solubility
These two elements of Step 1 set the standards by which a solution is judged and the limits placed on the process, such as cost or weight.
What are criteria and constraints?
High solubility means a substance easily does this in a liquid, like sugar does in water.
What is dissolves?
When solid matter dissolves, it does not disappear; instead, it does these two things.
What is breaks apart and spreads out?
This metal property describes how easily an electric current passes through a material.
What is electrical conductivity?
Name three properties of matter.
Hardness, color, reflectivity, electrical conductivity, thermal conductivity, magnetism, solubility
This is Step 3 of the design process, which involves creating something similar to real life so it can be tested fairly.
What is "Make a Model"?
You can measure a material's hardness by performing this specific type of test against another material.
What is a scratch test?
Liquids at this temperature cause particles to move slower, resulting in less matter dissolving.
What are cold (or colder) liquids?
This metal property describes how easily heat passes through a material to help cook food.
What is heat conductivity?
Unlike weight, which measures the force of gravity using a scale, this term refers strictly to the amount of matter an object is made of.
What is mass?
Step 5 of the design process involves checking if a solution works and meeting standards, keeping in mind that great inventions can come from these two things.
What are errors and mistakes?
Pumice demonstrates buoyancy because it floats, while a chunk of copper does this because its matter is less spread out.
What is sinks?
Allowing the liquid in salt water to evaporate in the sun leaves behind these visible structures, proving the particles were there all along.
What are crystals (or particles) of salt?
This property determines whether or not a metal is attracted to magnets.
What is magnetism?
