Mixtures/Solutions
What is a mixture?
What are the three properties of matter?
Solid, liquid, gas
What is solubility?
Solubility is when testing if something is soluble or insoluble.
What is a conductor
A conductor is something that lets heat and electricity through easily
What is a solution?
A solution is something that has two or more things that is not that easy to separate and does not keep its physical state and properties
What happens when solid turns into liquid?
Melting
What is relative density?
Testing whether something is more dense or less dense than water.
What is an insulator?
A insulator is something that does not let heat and electricity through easily
What is one way to separate iron filling, sand, and water
Use a magnet to get the iron fillings, then get the sand with paper filter.
