Demonstration of the long procedure for the quarters lab.

The flex camera was very handy to show the intricate procedural tasks.

I am showing the demonstration of copper quarters in front of one of my classes.

The source of the copper is copper coil.

Cutting the coil.

This sharp student is making sure of her measurement.

In this step acetone is being used to clean the dirt off the quarters.

Checking the battery connections. If they are hooked the opposite way, there will be no reaction.

Emmersing the quarter into the copper sulfate bath.

You can see the connections.

Checking the connections.

These two top students are good buddies and always get their lab correct.

One graduated early and they both got scholarships to the same college.

This step is similar to putting zinc on pennies - it's just on copper quarters here.

Heating the zinc coated and copper coated quarter over the bunsen burner to make a "Gold Quarter."

The money huddle - copper, zinc, and brass coated quarters.

Cartoon picture of some of my second period students holding their quarters.

3 top students with our Think Show project for second period.

A nice golden (brass coated) quarter

Comparing all 3 quarters - they look very nice, we were proud of our accomplishment.

Part of the glory of lab - is cleaning the equipment and glassware sometimes.

After the reaction of calcium carbide with water, a base is made in the water, turning red litmus paper blue.

The burning of acytelene gas in a big test tube.

Getting the test tube set up for the reaction.

This student has enjoyed watching the acetylene burn.

The middle student is a bit apprehensive.

Positive test for a base.

These students have just poured the calcium carbide into the water and are beginning to collect the gas.

These two are having fun collecting the acetylene gas.
