What is the formula for Density?
Density = Mass/Volume
100
What is mass?
How much matter is in something
100
Define volume
THe amount of space that an object has
100
What are criteria?
What are....Goals that must be satisfied to successfully achieve a challenge?
100
Fill in the blanks: Comparing the density of an object to the density of water can tell you whether the object will _______ or _______
sink, float
200
What is the density of a 36 kg block that has a volume of 6 cm^3
6.0 kg/cm3
200
What force pushes down on all mass on the earth?
Gravity
200
What are two scientific principles that keep a boat afloat?
What are matter and density? Gravity, Bouyancy, volume, mass, etc
200
What is matter?
Matter is anything that has mass and volume. Everything that takes up space. Everything you can touch, feel, see and taste
200
What is the name of the force that is the pull between two objects? It holds all objects on Earth?
What is gravity?
300
What is the density of an object with a mass of 45g and a volume of 9cm3
5 g/cm3
300
What tool is used to find mass and what is the measurement unit?
The tool is an electronic balance or a triple beam and it is measured in grams or kilograms
300
What are the three states of matter?
What are a solid, liquid and gas?
300
What are constraints? What were two boat challenge constraints?
Constraints are factors that limit how you can solve a problem. *Boat Challenge: we were limited to 10 minutes to design the boat, we were limited to a 5 x 5 piece of tin foil to build the boat, we were limited by the size of the boat it had to be less than 5 cm to fit into the small hole that went into the castle.
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
If Density = Mass/volume, what will happen to the density if the volume increases? Think about mass being 81 kg (this is constant) and the volume increases from 3 cm^3 to 9 cm^3
The density decreases.
400
When two boxes have the same mass, do they have the same density? Why?
No because volume effects the density and one box could be larger than the other.
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.
400
The weight of water that is pushed away by the boat is _______ to the weight of the boat? **We also say that the water is __________ by the boat.
What is .....equal? What is displaced
500
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 and gravity is affected by distance of two objects.
500
What are four scientific principles to float a boat?
Volume of boat... Surface Area Buoyancy.... Force pushing Up Gravity.... Force pulling down Density = Mass/volume Answer describes a minimum of 3 scientific principles for 500 points.
500
Each try or attempt you have to modify solutions to improve on a process is called a __________.
What is an iteration?
