Observation Something you notice.
A question that is measurable Research Question A question that is measurable
Collect Variables IV CV The thing you change. DV CV The thing you change. The thing that changes because you changed something. The thing that stays the same
Procedure The steps you take
Create proper graphs or tables Analyze Data Create proper graphs or tables
Conclusion Based off of the hypothesis, explain whether you were right or wrong, and why.
Newton's Three Laws 1st \ 2nd 3rd
Newton’s First Law What’s in motion stays in motion until a force is applied. What’s not is motion stays out of motion until a force is applied.
Newton’s Second Law The more mass something has, the more force that is needed to move it.
Newton’s Third Law With every force, an equal and opposite force is applied.
Gravity The force that pulls you to earth.
Acceleration When something speeds up.
Force Any influence that changes speed, shape, or direction.
Resistance The force that slows something down.
Potential Energy Energy that is not in use, but could be.
Kinetic Energy Energy in use.
Chemical Change Vs Physical Change Creates a new substance. Physical Change in look- shape, color, etc. BEFORE AFTER BEFORE AFTER
Homogeneous Vs Heterogeneous mixtures You can see the different particles. Homogeneous You can not see the different particles.
Compound Vs Element Vs Atom Two or more substances that are chemically combined. Element Atom A substance made of one What all matter is made up of type of atom.
The Seven Types of Electromagnetic Waves Radio Waves Microwaves Infrared Visible light Ultraviolet X-Ray Gamma Ray Gamma Ray
Radio Waves Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a soccer field or as short as a soccer ball. Radio waves don’t only bring music to your radio, they also carry signals for your TV and cell phones. Examples Am/Fm Radio Cell phone
Micro waves A subset of radio waves that can range from one meter to as little as a one millimeter. Examples Microwave Radar
Infrared Electromagnetic radiation with a wavelength longer than that of visible light. Examples Night vision Remote control
Visible Light Examples An electromagnetic radiation that is visible. Light bulb Camera flash
Ultra Violet Has a wavelength shorter than that of visible light, but longer than X-rays. Examples Tanning bed Scorpion flashlight
X-ray X-rays have a wavelength in the range of 0.01 to 10 nanometers. X-ray machine Satellites
Mechanical Wave A mechanic al wave requires a medium. Ocean waves Sound waves
