Analyze your data and draw a conclusion
Ask a question
Construct a hypothesis
What is the independent variable
The result, outcome, or what you are measuring
The ability for one substance to float
The one thing you change
The amount of things that you are using
What is the Law of conservation of mass?
The total of electricity on an object
The total mass before a chemical reaction that is the same as the total mass after the chemical reaction.
The ability of an object to burn

32
What are the four prices of information found in each box of the Periodic table of Elements?
Element’s name, power, protons, and electrons
Number of protons, neutron, electrons, and Ions
Element name, element symbol, atomic mass, atomic number
Time, space, soul, power, mind, and reality
What is the element of this symbol: He

What is Newton’s First Law?
A. The greater the force on an object, the greater its acceleration
B. If two objects are acted on by the same force, the object with less
mass accelerates more than the object with more mass
For every action (force) there is an equal and opposite reaction (force)
An object at rest stays at rest and an object in
motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
Would your mass be different on the moon
Maybe
Yes
No
I give up
What is weathering and erosion
Weathering is the breaking down of rock into smaller pieces by the action of wind, rain, and temperature change and erosion is the process by which wind, water, ice, gravity, or other natural forces move sediment over Earth's surface
