Scientific Method & Variables
This step of the scientific method involves making an educated guess. It is often phrased as an "if/then" statement.
Hypothesis
Describe particle movement in a solid.
The height of a wave from rest position.
Amplitude
The main organ of the respiratory system.
Lungs
Name the layers of the Earth.
Crust, Mantle, Outer Core, Inner Core
This variable is changed on purpose in an experiment. The manipulated variable.
Independent variable
This change of state happens when a gas becomes a liquid.
Condensation
This happens when a wave bounces as it strikes a surface.
Reflection
This structure is the basic unit of life.
Cell
Mountains form from this kind of plate boundary.
Convergent
This portion of an experiment does not receive the treatment or change.
Control Group
Describe how energy is exchanged when someone is holding an ice cube.
Thermal energy goes from the hands to the ice cube
Waves that need a medium to travel through (like sound).
Mechanical Waves
The brain of an eukaryotic cell.
Nucleus
This kind of rock forms due to immense heat and pressure.
Metamorphic
This term describes data that can be expressed with numbers. Example: There are 32 chairs in this room.
Quantitative
This change of state happens when a gas becomes a solid.
Deposition
The number of waves that pass a point in one second.
Frequency
The system that controls the body using electrical systems.
Nervous System
This person developed the Continental Drift Theory.
Alfred Wegener
When graphing information we used the acronym "DRY MIX". What does DRY MIX stand for?
(D)dependent, (R)responding, (Y)-axis
(M)anipulated, (I)ndependent, (X)-axis
Name the three types of heat transfer.
Conduction, Convection, Radiation
This type of wave is made when particles move perpendicular to the wave direction.
Transverse Wave
List the levels of organization from smallest to largest. (Hint: There are 5 levels)
Cell, Tissue, Organ, Organ System, Organism
This law of relative age dating states that rocks on the bottom are older than the rock layers above.
Superposition
