Phase Changes
What is a change in one state of matter (solid, liquid, gas) to another without a change in chemical composition?
Phase Change
What are the three states of matter?
What do we call a testable prediction?
Hypothesis
True or False: If a substance (such as oil) floats on top of water and they do not mix, that means that the oil has a HIGHER density than the water.
If a substance floats on top, it has a lower density. Higher density substances will drop to the bottom.
An explanation based on experiments- the most logical explanation
DOUBLE JEOPARDY
Scientific Theory
What type of change is change in size, shape, or state of matter? Hint: Does NOT change its identity when going through this change.
What is the amount of matter that each individual object contains?
DOUBLE JEOPARDY
Mass
What is the SECOND step to the scientific method
1: Ask a question
2: Research
What is the smallest unit found in everything
An atom
What is a rule of nature that sums up related observations to describe a pattern in nature?
A Scientific Law
True or False: Once an object has gone through a chemical change, it CANNOT go back to its original form.
What state of matter is an object in if the molecules are moving and floating around at a rapid pace?
Gaseous State
What is the change from a gaseous state to a liquid state?
DOUBLE JEOPARDY
Condensation
What is a group of two or more atoms bonded together?
DOUBLE JEOPARDY
A molecule
What phase change is when a solid state turns into a liquid state?
Melting Change
What type of phase change is it when a liquid state changes to the gaseous state?
DOUBLE JEOPARDY
Vaporization
True or false: Matter can only be non-living things
False
If an object is heavy and compact, what type of density does it have?
High Density
What is the term for: how much matter is packed into a substance?
DOUBLE JEOPARDY
Density
Matter is anything that has BLANK and takes up BLANK
MASS and Space
What is a change in one substance to another substance?
Chemical Change
What is how much space an individual object takes up?
Volume
What Law states that the mass of all substances present BEFORE a chemical change, must equal the mass of all substances AFTER a chemical change?
Law of Conservation of Mass
Why doesn't oil and water mix?
List in order the first 4 steps of the scientific method.
1- Ask a question
2- Research
3- Form a hypothesis
4- Create an Experiment
