Determination of Water Hardness
Students investigate water hardness. In this water hardness lesson plan, students determine the water hardness in 4 samples of water after buffering each. By using titration and an indicator, students can determine the amount of calcium...
Curated OER
RHS Campaign for School Indicator
Students study Ph and how acids and bases can affect it. In this indicators lesson students divide into groups and complete a lab activity to investigate what happens when they add indicators.
Curated OER
Making Soap
Students explore what chemical indicators are and use pH paper to determine if something is alkaline or basic. In this pH instructional activity students manufacture their own soap.

Cool Chemistry- DIY pH Indicator
Students study the differences between an acid and a base. In this pH lesson students view a demonstration then test chemicals in groups.
Curated OER
Acid(s)-Base(s) Detective
Students investigate acids, bases, indicators and universal indicators. In this acid and base lesson plan, students test 6 samples with litmus paper and determine if they are acids or bases. They separate out 7 samples using litmus paper...
Curated OER
Investigating Buffers
Students investigate buffers and their behaviors when used with acids and bases. In this buffers lesson plan, students use a pH meter and create buffered acidic and basic solutions. To each of the buffered solutions students add strong...
Curated OER
pH Lab
In this pH worksheet, students experiment with dilutions of acidic solutions to test for the pH using cabbage as an indicator. They then test a variety of substances for pH. On day two of the lab, they test conductivity of solutions and...
Curated OER
DNA Extraction
Students are able to extract and observe a visible amount of DNA from Escherichia coli cells. They discuss the properties of DNA. Students confirm the presence of DNA by a reaction with an indicator.
Curated OER
Acidity of Soda Pop
Pupils conduct an experiment to determine the acidity of three different brands of soda by adding a known volume of base until a pink color appears in the reaction vessel. They test fresh and flat soda, observe any differences, and draw...
