Properties of Matter – How does the structure of matter affect the properties and uses of materials?		What is Matter? Element Song		Safety! Safety! Safety!
6.1 - Materials can be classified as pure substances or mixtures, depending on their chemical and physical properties.		Classifying Matter Chart Classification of Matter
¨ Mixtures are made of combinations of elements and/or compounds, and they can be separated by using a variety of physical means.		Mixtures More Mixtures
¨ Pure substances can be either elements or compounds, and they cannot be broken down by physical means.		Mixture Activity Fun = Table of Condiments That Periodically Go Bad Variables

"You know the oxygen masks on airplanes? I don't think there's really any oxygen. I think they're just to muffle the screams." - Rita Rudner

Q: what do you call the leader of a Chemistry gang?
A: The nucleus

FROM THE MOUTHS OF SCIENCE STUDENTS:

"Nitrogen is not found in Ireland because it is not found in a free state."

"H₂O is hot water, and CO₂ is cold water."

"To collect fumes of sulphur, hold a deacon over a flame in a test tube."

"When you smell an odorless gas, it is probably carbon monoxide."

"Water is composed of two gins, Oxygin and Hydrogin. Oxygin is pure gin. Hydrogin is gin and water."

"A super saturated solution is one that holds more than it can hold."

These comments come from test papers and essays submitted to science and health teachers by elementary, junior high, high school, and college students and compiled at the NEA Life Sciences Symposium, Kansas City, Kansas. As the originator noted, "It is truly astonishing what weird science our young scholars can create under the pressures of time and grades."
