The book Chemistry on a Budget contains inexpensive chemistry labs that are useful with easy to obtain materials.
The early labs include the topics of Significant Figures, Density (3 labs), the Separation of a Mixture (including coverage of Percent Composition), and Liquid Chromatography. These are safe labs that cover essential information, giving you time to emphasize Lab Safety and get Lab Safety Contracts signed.
There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
You can buy this lab book for $23 at amazon.com or lulu.com. It will take 1-2 weeks to get to you -- Order Now. It’s a great resource!

The 2016 Nobel Prize in Chemistry was recently awarded this Wednesday, October 5, 2016:
“The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2016 to
University of Strasbourg, France
Sir J. Fraser Stoddart
Northwestern University, Evanston, IL, USA
Bernard L. Feringa
University of Groningen, the Netherlands
‘for the design and synthesis of molecular machines’ "
“The laureates share the 8 million kronor ($930,000) prize for the "design and synthesis" of molecules with controllable movements, which can perform a task when energy is added, the Royal Swedish Academy of Sciences said.”
“Nanotechnology — the creation of structures on the scale of a nanometer, or a billionth of a meter — has been a field of fruitful research for a couple of decades. Now, scientists are learning how to construct tiny moving machines about one-thousandth the width of a strand of human hair.”
“The machines conceived by today's laureates are a thousand times thinner than a strand of hair.
They could slip inside the human body to deliver drugs from within - for instance, applying pharmaceuticals directly to cancer cells.
This field of nanotechnology could also yield applications in the design of smart materials. …
The prize recognises their success in linking molecules together to design everything from motors to a car and muscles on a tiny scale.”
“The first Nobel Prizes are awarded in Stockholm, Sweden [in 1901], in the fields of physics, chemistry, medicine, literature, and peace. The ceremony came on the fifth anniversary of the death of Alfred Nobel, the Swedish inventor of dynamite and other high explosives. In his will, Nobel directed that the bulk of his vast fortune be placed in a fund in which the interest would be ‘annually distributed in the form of prizes to those who, during the preceding year, shall have conferred the greatest benefit on mankind.’ Although Nobel offered no public reason for his creation of the prizes, it is widely believed that he did so out of moral regret over the increasingly lethal uses of his inventions in war.”
Here are two articles that provide more background about the Nobel Prize:
