What is pH and Why is it Important?

Chemistry or physical science fledglings get comfortable identifying acids and bases with a variety of pH indicators. They discover that different indicator solutions have different ranges, practice testing soil acidity, and use antacids...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun resource. Engage them...

Lead the class in a colorful exploration of acids and bases as they learn to differentiate between the two. They identify common items considered acidic and basic, then explore their strengths and weaknesses. They titer solutions and...

There is a chart to complete with results of the titrations for the 14 different pH indicators.  There are also nine questions for data analysis, and then four problems requiring equations, molarities, and pH values.

Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

An acid/base indicator that's made of blended red cabbage and water is used to demonstrate the various reactions that an acid/base solution goes through when some carbon dioxide gas is added. The best way to add the carbon dioxide is to...

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

Watch as acids and bases put smiles on their faces. Young chemists learn the concept of acid-base titration firsthand in a microscale experiment. Working groups collaborate, titrate, then use their data to determine the concentration of...

Middle schoolers prepare a test solution whose color changes when an acid or a base is added. They determine whether various household substances are acids or bases and look for patterns in the results. Students determine how their test...

Looking for a comprehensive plan for teaching acid-base chemistry? Science scholars discover acid-base interactions through a thoughtfully written unit. The resource is divided into paced activities and individual work designed to...
