For inexpensive chemistry lab ideas 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 -- they are very handy for the beginning of the school year.
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.

I realize that during the school year it’s very difficult to keep up with research topics. During the next few weeks, I will talk about some current research going on in the science community.
I posted last month about the concerns about Abandoned Mines on 7/15/2015. I did not anticipate the current accident in the Colorado mine.
There are several news reports about this accident – here’s one from National Public Radio (NPR) that is pretty comprehensive:
On source reminds its readers that "[t]housands of mines with toxic water lie under the West...”
It is quite shocking to see the river turned brown as the waste continues through the waterway. Here is a local news story as the events unfolded:
Here is a shorter article about the Colorado mine spill that might be useful for a class assignment:
This is a very timely concern so you may want to use it during the introductory days of the course -- or resurrect it later when studying about The Periodic Table.
Students could read a chosen article about the incident, summarizing it or listing 10 facts, and/or have a discussion about the pros and cons of mine clean-up.
This Blog contains several entries that would be helpful to your chemistry classroom. Remember, you can check out the Topic List to help you to find past Blog entries.
