Matter Lessons 1-3

Observing matter through sight as well as your other senses is

• a hypothesis

• direct evidence

• indirect evidence

A hypothesis is

• a lucky guess

• a logical guess

• a bad guess

A set of clues that scientists use to make logical guesses about things they cannot see or test directly is

• microscopes

• ecosystems

• indirect evidence

Matter is

• anything and everything that has mass and takes up space

• Figuring out what is wrong

• deciding what is important

The states of matter are

• solid, liquid, plasma, mass, density

• solid, liquid, volume, plasma, gas

• solid, liquid, gas, plasma, Dole-Edision Condensates

• solid, liquid, gas, plasma, Bose-Einstein Condensates

Solid, liquid, and gas are

• the most common states of matter

• the three people know best

• both of the above

• None of the above

Solids

• have definite size

• have definite shape

• a book is an example

• All are correct

Liquids

• Have definite volume

• Have no definite shape

• Water is an example

• All are correct

Gas

• Helium is an example

• Has no definite size

• Has no definite shape

• All are correct

Super hot gases that take on high-energy electrical charges such as florescent lights are

• Solids

• Bose-Einstein Condensates

• Plasma

• Liquid
