The upward force of water, another liquid, or air that keeps things afloat.
What is Buoyancy?
100
The amount of matter making up an object.
What is Mass?
100
A state of matter that has a definite shape and takes up a definite amount of space.
What is a Solid?
100
A state of matter that takes up a definite amount of space, but has no definite shape.
What is a Liquid?
200
A state of matter that does not take up a definite amount of space and has no definite shape.
What is a Gas?
200
A system of measurement based on units of 10. These units such as the meter, kilogram, and liter are used in most countries and in all scientific work.
What is the Metric System?
200
The number of units that fit along one edge of an object.
What is Length?
200
The number of unit squares that fit inside a surface. Length x Width = ?
What is Area?
200
The amount of space an object takes up. Length x Width x Height = ?
What is Volume?
300
The measure of the pull of gravity between an object and Earth.
What is Weight?
300
The amount of matter in a given space. In scientific terms, it is the mass per unit of volume.
What is Density?
300
Attracting force between objects (the force depends on mass and distance).
What is Gravity?
300
This measures weight.
What is a Scale?
300
An object has the same amount of THIS anywhere, however, its weight can differ.
What is Mass?
400
Matter can exist in these 3 forms.
What is a gas, liquid, or solid?
400
This happens to matter we use.
What is reduce, reuse, and recycle?
400
These particles are packed together tightly.
What is a Solid?
400
These particles are not as tightly packed together.
What is a Liquid?
400
These particles move about freely and are far apart.
What is a Gas?
500
This has mass and the property of density.
What is Matter?
500
A characteristic of matter that can be observed.
What is a Property?
500
Color, texture, shape, size, hardness, smell, temperature, magnetic attraction, ability to dissolve in liquid, and buoyancy are these.
What are Properties of Matter?
500
These help to choose the right types of matter for different jobs.
