300
What are the three states of matter?
What are a solid, liquid and gas?
300
What are constraints?
Constraints are factors that limit how you can solve a problem.
300
Name all of the units for density (volume, mass, density)
Volume = mL or cm3
Mass = g, kg
Density = g/mL or g/cm3
400
What will happen if you drop an object into water that has a density of 1.33g/cm3?
It will sink
400
When two boxes have the same mass, do they have the same density? Why?
No because volume effects the density.
400
What is buoyant force?
What is the upward push that keeps objects floating in liquid?
400
Explain the difference between an atom and a molecule.
Matter is made of extremely small particles called atoms. Molecules are a combination of two or more atoms.

Name the 3 states of matter from highest to lowest density
Solid = the highest density
Liquid = "medium" density
Gas = the least density
500
Does your mass or weight change on other planets? Also explain what causes this to happen.
Your weight changes. This happens because weight is affected by gravity.
500
What are the scientific principles to float a boat?
Volume of boat... Surface Area
Buoyancy.... Force pushing Up
Gravity.... Force pulling down
Density = Mass/volume
