Science - The Basics
This is the gathering of information using senses or with the aid of instruments
What is Observation
Anything that has mass and takes up space
This is the energy stored in chemical bonds
What is chemical energy?
This is the change in an objects velocity
What is acceleration?
This is a push or a pull that acts on an object
What is force?
This type of measurement uses milliliters (mL) and describes the amount of liquid.
What is Mass
True or False, a compound has the same properties as the elements that compose it
What is false?
This reaction type will always have oxygen as one of the reactants
What is combustion reactions?
The physical measurement that contains both magnitude and direction
What is vector quanity?
What is friction?
This observation describes the bubbles in the jar as being far apart, making it a qualitative observation.
What is qualitative
This physical characteristic of a substance indicates the temperature at which it changes from a solid to a liquid
What is its melting point?
Compounds made of only two elements
What is Binary compounds?
This measurement requires a direction
What is velocity?
This force causes flat things to fall more slowly
What is air resistance?
This explains that science uses evidence and experiments to support ideas, not to prove them as 100% true forever
What is science is about collecting evidence, not proving things?
This is the name of the phase change process in which liquid becomes a gas
What is evaporation?
This is where the energy comes from when energy is released by a chemical reaction
What is a chemical bond?
The rate at which an object is moving at a given moment in time
What is Instantaneous speed?
Newtons first law states that "an object in motion (or at rest) will...
What is stay in motion?
This is a representation used by scientists to help explain, describe, or predict how something works
What is a scientific model?
While most matter on Earth is solid, liquid, or gas, this fourth state of matter exists only at very high temperatures
What is plasma?
This is the minimum amount of energy needed for a chemical reaction to start
What is activation energy?
This is an example of motion where an object’s speed and direction do not change
What is zero acceleration?
This universal force is the strongest in creation
What is a strong nuclear force?
