Nature of Science
The variable that is changed by the scientist
independent Variable
This type of change occurs when a material changes its physical properties cuchas it's shape but not its substance
Physical Change
This form of energy tells you how hot or cold an object is
Thermal (heat) energy
This state of matter has a definite shape and volume
solid
This state of matter has a definite volume but not a definite shape.
Liquid
The step by step process that scientist follow when completing a science investigation
Procedure
What are the 3 states of matter?
solid, liquid and gas
True or False: Light can reflect, refract and vibrate
False. Light can reflect, refract and absorb
This property of matter can be measured by using a balance. It measures the amount of matter in a substance.
Mass
This variable is observed by the scientist
Dependent variable
Scientists copying an experiment that was done to ensure the conclusions are valid.
Replication
Which of these conditions has the greatest effect on how quickly a substance changes from one state to another?
a. color
b. light
c. shape
d. temperature
D. Temperature
This type of energy is stored in matter and can be released by a chemical reaction
Chemical energy
This property of matter measures the amount of space matter takes up. Can be measured using a graduated cylinder, beaker or measuring cup.
Volume
Scientists repeating this test multiple times to get the most accurate information
Repetition
This variable/factors remains the same in the control group and experimental group
Controlled variable/ Constants
This type of change occurs when one type of substance is changed in a new substance.
Chemical change
This type of energy is the energy an object has due to its motion or position.
Mechanical
This property of matter is the description of how an object feels.
Texture
This form of energy is the energy of sound waves as they travel.
Sound Energy
This group is tested in a scientific investigation/experiment
Experimental group
True or false: burning, cooking, rusting, and decaying (rotting) are types of physical changes.
False
This form of energy comes from the movement of charged particles
Electrical Energy
This state of matter has no definite volume or shape.
Gas
True or False: You can speed up the rate of dissolving by increasing temperature, constant stirring and surface area
True
