States of Matter
Anything that has mass and volume
What is Matter
Solid Changes to liquid
What is Melting?
Your best guess as to what will happen in your experiment written as an “If… then statement”
What is a hypothesis?
Are Changes in matter that do not change what the matter is. Example: chopping wood into smaller pieces.
What is a physical Change?
the things you need to do your experiment.
What are Materials?
Firm and Stable in shape. Always has the same volume
What is a solid?
When gas turns into a liquid
What is Condensation?
The directions or steps you take to do the experiment.
What is Procedure?
Gas Changes into a solid.
An observation that you make using your senses.
What is a qualitative observation?
Solid, Liquid or Gas?
What are the three states of matter
When solid turns into a gas.
An observation that can be measured.
What is a Quantitative observation?
When Liquid turns into a Gas.
What is Vaporization?
The variable that is changed. Ex. Planting in soil, rocks or Sand.
What is an Independent variable?
a substance or matter in a state in which it will expand freely to fill a whole container. No set shape or volume
What is a gas?
Liquid turns into a solid
What is Freezing?
Let other scientists know what your research was and what you found out
What is Report Findings?
A reaction that absorbs heat.
Example: Baking a cake
What is Endothermic Reaction?
a variable that stays the same throughout the experiment. Ex. All of the plants will get the same amount of sunlight and water.
What is Control variable?
A substance that flows freely but is of constant volume.
Happens when one or more chemical substance is transformed into one or more, different substances.
facts and statistics collected together for reference or analysis.
What is Data?
Example: A candle Flame
What is an Exothermic Reaction?
The variable that you are measuring. Ex. The height of the plants
What is Dependent Variable?
