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.
A 5-Star Customer Review of Chemistry on a Budget at amazon.com states:
“[S]traight forward, to the point, using household chemicals…this is the lab book for you.
I teach high school chemistry and this is exactly what i was looking for. Labs included simple household chemicals that could be easily found. Nice format, easy to follow along procedures, and touches on every topic of our chemistry curriculum.”
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!

Your chemistry students are studying energy and the transformation from potential to kinetic forms.
“The constantly churning oceans that cover most of the Earth offer an inexhaustible source of clean energy. The amount of recoverable energy embedded along the continental shelf of the United States, for example, amounts to almost a third of all the electricity the country uses in one year…”
“Off the coast of Hawaii, a tall buoy bobs and sways in the water, using the rise and fall of the waves to generate electricity.
The current travels through an undersea cable for a mile to a military base, where it feeds into Oahu's power grid—the first wave-produced electricity to go online in the U.S.
By some estimates, the ocean's endless motion packs enough power to meet a quarter of America's energy needs and dramatically reduce the nation's reliance on oil, gas and coal. But wave energy technology lags well behind wind and solar power, with important technical hurdles still to be overcome.”
“Harnessing wave power is more complex than the process of converting other renewable energy sources like wind or sun into electricity. Wave heights and frequencies can vary wildly over time and from one shoreline to another. Seawater is highly corrosive. And storms can turn reliable and predictable waves into machinery-destroying battering rams.
The energy market is an equally extreme environment. To survive it, commercial wave energy converters, which the Wave Carpet is on track to become, must produce electricity at a cost equal to, or lower than, that of fossil fuels or more established renewables like solar and wind.”
Another project using the same basic idea is being pursued in Japan.
“Since 2013…researchers have been strategically placing specially-designed turbines along the shoreline to convert the kinetic energy of the north-flowing Kuroshio current off the Japanese coast into usable electricity.
The turbines are inspired by the ocean; their flexible blades bend like dolphin fins and turn at a speed that ensures creatures can escape if caught in their clutches.
The turbines’ support structure is modeled on the flexibility of flowers. Built to withstand extreme weather and move with the relentless waves, rather than stand rigidly against them, the turbines bend like the stem of a flower bends back with the wind... They are anchored to the sea floor with mooring cables.
For ideal wave conditions, the turbines are planted among coral reefs and by tetrapods, which are pyramid-shaped cement structures built along coasts to break waves and prevent coastal erosion. The axis is attached to a generator, which converts wave energy into usable electricity that is then delivered by cables to land. A ceramic mechanical seal protects electrical components inside the turbine from saltwater and corrosion for up to 10 years.”
Here is another area of energy generation that your students can read about as a Homework or Extra Credit assignment.
