Using a ruler, how do you measure the volume of a regular solid (like the box and textbook at station 6)?

multiply length x width x height

200

What tool is used to measure mass?

Electronic balance

200
Specific gravity is useful because we can calculate if an object will ______ or _______ in water.
What is sink or float.

Calculate the volume of a hairbrush if the water in the graduated cylinder was 123 mL before the hairbrush was put in and the volume of the liquid after the hairbrush was submerged rose to 256 mL.
What is 133 cm3 or 133 mL
200

What unit is used for the density of a liquid?

g/mL

A crayon is placed into a graduated cylinder with 15mL of water in it. After the crayon is placed into the cylinder, the water level rises to 19mL? What is the volume of the crayon?


BONUS 200 POINTS - What term is used to describe the difference in how much the water moves?

4mL

Displacement!

What is the metric system's base unit of mass?

meters (m)

True or False: Density is a property of matter that is used to identify unknown matter. Density is like a fingerprint, no two types of matter have the exact same density.
What is true.

If someone's weight on the Earth is 150lbs, how much would they weigh on the moon? (Hint: the moon has 1/6 the gravity of Earth.)
What is 25lbs
300

What unit is used for the density of a solid?

g/cm3

400

To measure the volume of liquids I would read the numbers on the graduated cylinder by looking at the ________ of the meniscus. 

bottom

400
True or false: Mass is the same as weight

FALSE - Mass is the amount of stuff, Weight is the influence of gravity on mass

400
True of False: Matter always has the same density regardless of how much or how little of the matter is present. For example, aluminum has the same density from car rims to nails.
What is true.
400
If a person has a mass on 68kg on Earth, what is their mass on the moon?
What is 68kg - MASS NEVER, EVER, EVER CHANGES! THE AMOUNT OF MATTER IN AN OBJECT DOES NOT CHANGE BECAUSE OF GRAVITY. ONLY WEIGHT CHANGES BECAUSE OF GRAVITY.

What tool is used to find the volume of a liquid or an irregularly shaped solid?

graduated cylinder

500
The relationship of mass, weight, and volume is ....
What is more mass = more gravity and more gravity = more weight.
