Hi Chem gurus! I need a good lab for introducing orbitals to high-schoolers. Some of them already know about electron configurations; others are seeing this for the first time. Typically when I introduce the subject half of the class is yawning and the other half is completely confused. I am looking for a good hands-on lab activity that I can do that will help them visualize orbitals. Somethi...

I like to give students a chance to take home their chemistry experiments: they use red cabbage juice to find the pH of acids and bases around the house, for example. It is amazing the creativity that they show in finding new things to test. (I have learned about the pH of quite a few household items that I would not have thought to test.)
I would like more ideas in this vein. It is true t...

Hi Biology Gurus! I am perplexed by a lab I am trying to prepare for my students to do. I want to show them that a living thing (yeast) can generate a voltage. I read about an activity that does this by putting the yeast into lime jello ( http://www.instructables.com/id/Lime-Jello-Yeast-and-Carbon-Paper-Fuel-Cell/ and http://thinkbiologically.com/wp-content/uploads/2012/03/Micr...Cells.pdf) ...
