For inexpensive chemistry labs to expand your repertoire, buy my lab book Chemistry on a Budget for $21 at amazon.com or $23 at lulu.com.
Chemistry on a Budget contains several labs that are great for the beginning of the school year! Topics used include Significant Figures, Density (2 labs) and Physical Separation techniques.
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.
It will take a week or so to get to you, so Order Now!

Most chemistry classes start with the basics, Physical and Chemical Change. As an extension of the topic, the current state of Recycling programs in the United States is an interesting discussion.
Here is a brief list of 11 Facts about Recycling:
This is a 2 minute video about how the Materials Recovery Factories (MRFs) work:
“Consumers are part of the problem. While some people pat themselves on the back for the plastic bags and greasy pizza boxes they try to recycle, the MRFs [Materials Recovery Factories] can't process them.”
I have to admit, I’ve put greasy pizza boxes in the recycling bin (red face)…
But Does Recycling Work? Here’s a 6 minute video discussion talking to a commentator I’ve featured in this blog many times:
Here is the 5 minute video What Prevents Recycling? referred to in the previous vi
Here is a discussion of the Costs/Benefits of Recycling from Popular Mechanics:
“If recycling is truly becoming profitable, then that should end the debate--we can simply let the market decide what to recycle. The problem…is that recycling markets don't function smoothly. If you drink a bottle of water, the apparent cost to you of throwing out the empty or recycling it are identical: zero. One way to create incentives for recycling is a "pay as you throw" policy, where homeowners pay for garbage collection based on the size of their garbage cans. More than 7000 communities, serving about a quarter of the U.S. population, have introduced this policy with success--their recycling rates are about 30 percent higher as a result.”
Recently, New York City is putting a moratorium on recycling for 18 months to save money:
“How much paper, glass and aluminum get on the market also affect how much money cities lose on their programs. Right now, these goods are generally commanding low prices.”
Here is another article about the drop in oil prices and how it has affected the cost of “virgin” vs. recycled plastic:
The Cost/Benefit of Recycling is a good topic for student research and discussion, and is handy for an Extra Credit assignment as well!
