This image shows what the state of matter is as well as the speed of movement.
What is a solid which has a definite shape and size.
100
What is the relationship between mass and gravitational force?
The greater the mass the greater the gravitational force.
100
Describe the wind patterns on the earth?

How many elements are there
118

What are the 5 Biospheres of Earth?
Biosphere- All living things,
Hydrosphere- all water on Earth
Geosphere-all land and soil on earth
Cryosphere- all frozen water and ice
Atmosphere- all gases on earth
200
Why were multiple perspectives important to the development of cell theory?
What is Multiple perspectives bring new ideas to the table. Without new ideas, scientific knowledge goes unchallenged
200
What is Gravity?
what is a non contact force that is attrative force that exists between all objects with mass.
200
How does Friction effect an object when coming into rubbing contact?
slow or stops the object
200
What type of heating is this?
Conduction because it requires contact
200
What is the greenhouse effect?
It helps keep heat in to sustain life but the burning of fossil fuels makes the gases more heat,
300
How might this lead to the strength of science?
What is Scientific knowledge is durable because it is open to change as new evidence or interpretations are encountered.
300
What is a contact force give an example?
What is a push or pull force on an object for example applied force, normal force or elastic force.
300
What is weathering?
Weathering is the breaking down of material.
300
What is potential energy?
Wha is stored energy.
300
Why is the ozone layer important?
protects us from the uv rays of the sun.
400
Why might scientific theories change over time?
What is Scientific theories change as new evidence is discovered or new scientific interpretations are formed.
400
What do two opposite poles of magnets do to each other?
Attract
400
Explain the three types of variables in a scientific experiment?
controlled- these variables do not change these stay the same throughout your experiment.
inDependent varible=this is the variable and the only one you are testing
depentdent varible-theses are used to measere against the independent varible.
400
What is kinetic energy?
What is the energy of motion.

A scientific theory is a well-supported and widely accepted explanation of nature that is testable. Why is it important for scientific theories (claims and knowledge) to be testable with experiments?
What is Scientific theories need to be testable to ensure that they are based on empirical evidence and not other ways of knowing. Additionally, they need to be testable, so that they may be repeated and continually challenged. They must be continually challenged to ensure that the best possible explanation is available
500
What is the difference between a balanced force and an unbalanced force?
A balanced force on an object has an equal force that does not allow form movement or changes. Unbalance has force(s) acting upon an object that causes a change in the object's location, directions, and or speed.

Ph scale - Acids are between what numbers
What numbers are neutral? and base?
0-5.5ACIDS
6-7.5 Neutral
8-14 bases/basic
500
What is the law of Conservation of energy?
That energy can not be destroyed or created only transferred.
500
What is the difference between weather and climate?
Weather changes by the day,Climate changes over time /yearly/ seasonally.
