How Does Matter Change
Science Review
100
This is anything that has mass and volume.
What is matter?
100
A softball floats and a popcorn kernel sank. We would say that the popcorn kernel had a greater of this than a softball.
What is density?
100
This is the combination of two or more substances that can be seperated.
What is a mixture?
100
This is a change in the size, shape, or state of matter.
What is a physical change?
100
These are the big white puffy clouds in the sky that seem to form picture.
What are cumulus clouds?
200
This state of matter has particles that are very close together and hardly move.
What is a solid?
200
This is the measure of the amount of matter in an object.
What is mass?
200
I can use this to seperate metals out of a mixture.
What is a magnet?
200
This is what we call the temperature (100 degrees celsius) that causes liquid water to boil and change phases to a gas.
What is the boiling point?
200
Water would be considered this kind of resource.
What is natural resource?
300
This is the state of matter where the particles are very spread out and moving rapidly.
What is a gas?
300
This is the measure of how much space an object takes up.
What is volume?
300
This a special mixture where one substance dissolves into another.
What is a solution?
300
In this change of matter, particles of one substance are changed to form a completely new substance.
What is a chemical change?
300
This is what happens to a puddle of water during the water cycle when the sun shines on and heats up the water.
What is evaporation?
400
This is the state of matter where the particles are sort of close together and moving around, but not too rapidly.
What is a liquid?
400
This is the instrument we use to measure volume.
What is a ruler?
400
In a solution, this is the substance that the other substance dissolves into (we can still see this substance).
What is the solvent?
400
This is the change of matter when you go camping a burn some wood to form ashes.
What is a chemical change?
400
These are called "the building blocks of life"...all livings things have these.
What are cells?
500
When this is added to something or taken away from something a phase change occurs in matter.
What is heat?
500
This is the instrument we use to measure how much mass matter has.
What is a pan balance?
500
In a solution, this is the substance that dissolves into the other substance (we can no longer see this substance).
What is the solute?
500
This is the energy added or subtracted from matter, which causes particles to speed up or slow down, to cause phase changes in that particular matter.
What is heat energy?
500
These are the five steps in the Scientific Method.
What are 1. Make observation or ask question, 2. Hypothesis 3. Plan experiment 4. Do experiment/test hypothesis 5. Draw conclusions
