Usda: Virtual Labs: Testing and Adjusting P H

Complete a variety of activities to examine the pros and cons and ethical issues behind genetic testing. Your high school learners will role play and examine various scenarios to determine if genetic testing is justified.

If you knew that you were likely to develop Alzheimer's disease in your future, how would it affect your life in the meantime? This and other similar thought-provoking questions are discussed in a lesson plan about the availability of...

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead,...

After looking at the many aspects of the issues behind genetic testing, learners are exposed to the pros and cons and must take a stand by writing a position paper. They will view the "Who Gets to Know?" video and/or reading case studies...

Pupils learn how to control food spoilage by adjusting the food's pH. They see that one of the most dangerous bacteria can grow in food if people don't handle and store food properly. Using knowledge of the bacteria's preferred pH,...

Strong acids and bases don't hesitate to dissociate! Your chemistry class won't hesitate calculating pH either, thanks to an engaging simulation. Individuals perform a series of pH determinations on paper, then use the virtual lab to...

Colorful cobalt complexes make a great way to learn about Le Chatelier! Eager chemists explore equilibrium through a virtual lab. Individuals use solutions with two different concentrations and observe the color changes that indicate...

No chemistry lab? No problem! Scholars use a virtual lab to determine the solubility product of four different chemicals. They then use the results of their experiments to see if higher solubility product values equal greater solubility.

Looking for an easy way to give your class experience with acid-base chemistry outside the lab? Try a detailed interactive that puts them in total control! Young chemists determine the dissociation constant and concentration of an...

You'll feel strongly about this weak acid and base virtual lab! Scholars experiment with the wonders of dissociation constants in a simulated lab environment. The accompanying written work includes buffer preparation, titration curves,...
