A number system based on 10..
Metric system.
100
Mass is measured by using a ___________.
balance.
100
The metric unit for weight is called a A. ton B. kilometer C. newton D. liter
C. newton.
100
A two ounce, solid steel marble is place in a bathtub full of water. The marble sinks to the bottom. An empty, two pound steel bowl is placed in the bathtub and it floats. Why?
The air inside the bowl makes it more buoyant than the steel ball. The density of the bathtub water is greater than that of the empty bowl, so the bowl floats. The water's density is less than that of the solid marble, so the marble sinks.
200
The distance from one place to another...
Length!
200
The metric unit of weight is a __________.
newton.
200
Why do objects weigh less on the Moon than they do on the Earth? A. Objects do not have as much mass on the Moon. B. The area of an object decreases on the Moon. C. There is a different scale of measurement used on the Moon. D. The pull of gravity is not as strong on the Moon.
D. The pull of gravity is not as strong on the Moon.
200
How does a hot air balloon float?
The air on the inside of the balloon is heated, so it is less dense than the outside of the balloon, where the air is cooler. The particles spreading out inside of the balloon cause it to float.
300
The effect of gravity on the mass of an object...
Weight!
300
The measure of square units on the surface of something is ______. This can also be found by multiplying length x width.
area
300
Study the problem below: Mass x ______ = Density Which of the following belongs in the space? A. Buoyancy B. Volume C. Area D. Weight
B. Volume
300
Why should scientists use the same units of measure for their experiments?
All scientists should use the same standard units of measure so that their measurements will all be consistent with one another. This way, scientists can easily compare results of repeated experiments.
400
The force that pulls any two objects toward each other..
Gravity.
400
Volume is ....
the amount of space that an object takes up. It is also what you get when you multiply length x width x height!
400
Which of these is an example of volume? A. The number of squares that cover a surface B The number of units that fit from one end of a line to the other C. The number of units that fit across a shape from one side to the other. D.The number of cubes that fit inside a box.
D.The number of cubes that fit inside a box.
400
How is the area of a rectangle measured?
Its area is measured by multiplying the rectangle's length by its width.
500
The mass of an object divided by its volume...
Density.
500
If Santa Claus stepped on a ______ to measure his ______ he would be more happy with himself if he was to do so on the ______ rather than earth.
scale, weight, moon.
500
