Experimental Design
A factor that doesn’t change in an experiment when you are performing the lab. This item stays the SAME throughout the entire lab.
Constant
Water molecule - What atoms make up this compound and how many atoms of each type?
2 Hydrogen atoms and 1 oxygen atom
Protons and neutrons are found in this _____. This is the inside of an atom.
nucleus
Tides are affected most by
Moon's gravity
Instrument to measure air pressure?
barometer
The factor intentionally changed: “I changed it.”
IV (Independent Variable)
What is the universal solvent?
Water
* Negative charge
*Spins outside of the nucleus
electron

Venus
Type of front that has a red symbol that looks like a half circle.
warm front
The effect of the change (caused by the IV). What are you measuring at the end of the experiment?
DV (Dependent Variable)
When many water molecules on the surface of water pull on one another this is created. An example is when you see a bug floating on top of the surface.
Surface Tension
Two gases that makeup 99% of the Earth's atmosphere. Include names and which one has the most.
Nitrogen – 78%
Oxygen - 21%

Mesosphere
An educated guess; written as an ‘If…, then…’ statement
hypothesis
What does it mean when water is polar?
Oen end is positive and one is negative, so it is a sticky molecule.
How many atoms are there in this compound? H2O
3
We have seasons because __ and ___
tilt and revolution
Which is more dense warm or cold air and explain your reasoning.
Cold air is more dense. When temperature decreases the molecules get closer together.
This is the level that is being used as the standard to compare the changes. This is the "normal" level.
control
The movement of a liquid through or along the surface of another material despite other forces, such as gravity.
Capillary Action
How many total atoms are there in this compound?C6H12O6
24

Give an example of radiation, conduction and convection
Radiation Example: The Sun’s heat radiates to Earth, warming our air, soil, and water.
Conduction Example: Touching hot sand with your feet.
Convection: Example: Water boiling, wind currents, ocean currents, and hot air balloon.
