The book Chemistry on a Budget contains inexpensive chemistry labs that are useful with easy to obtain materials.
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!

“It’s not a hoax. There’s no conspiracy. And no exaggeration. What follows are 137 years of diligently kept scientific records that show how humans are transforming Earth’s climate. The bright red line represents 2016—the third consecutive year to set a new record. The streak is the steepest and most sustained surge in planetary temperatures in the modern age.”
“[In 2016], global warming reached record high temperatures — and if that news feels like déjà vu, you're not going crazy.
The planet has now had three consecutive years of record-breaking heat.
The National Oceanic and Atmospheric Administration has just released its annual State of the Climate report, which says it's the hottest it has been since scientists started tracking global temperatures in 1880.
A separate analysis, by NASA scientists, came to the same conclusion.”
“Temperatures over the Earth's continents and oceans in 2016 were 1.1 degree Celsius (1.98 degrees Fahrenheit) above the pre-industrial average, according to the WMO. That means we are already a majority of the way to the 1.5-degree warming goal set at the Paris Climate Agreement in 2015.”
This article contains a brief 1 ½ minute news report dated 1/18/2017 about this recent announcement.
Below this video clip is a graph of global temperature vs. time.
“Last year’s warmth was manifested across the planet, from the warm tropical ocean waters off the coast of northeastern Australia, where the Great Barrier Reef experienced its worst coral bleaching event on record and large scale coral death, to the Arctic, where sea ice hit regular monthly record lows and overall temperatures were also the warmest on record, at least from January through September 2016.”
“Globally, 2016 edged out 1998 by +0.02 C to become the warmest year in the 38-year satellite temperature record, according to Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville. Because the margin of error is about 0.10 C, this would technically be a statistical tie, with a higher probability that 2016 was warmer than 1998. The main difference was the extra warmth in the Northern Hemisphere in 2016 compared to 1998. ...
[According to Dr. Cristy,] 'The question is, does 2016's record warmth mean anything scientifically? I suppose the answer is, not really. Both 1998 and 2016 are anomalies, outliers, and in both cases we have an easily identifiable cause for that anomaly: A powerful El Niño Pacific Ocean warming event. While El Niños are natural climatic events, they also are transient. In the study of climate, we are more concerned with accurately identifying long-term temperature trends than we are with short-term spikes and dips, especially when those spikes and dips have easily identified natural causes.’ ”
