What is pH and Why is It Important?
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...
Curated OER
Acids, Bases and Salts
Students explore acids, bases and salts. They define acid and base. Students describe the characteristics and properties of acids and bases. They relate the processes of ionization and dissociation to the formation of acids and bases.
Curated OER
The Measurement Of Acids And Bases
Young scholars investigate the differences in chemistry between an acid and a base substance. They conduct measurements based upon the pH scale and then answer the questions included in the instructional activity. The information for the...

Can Acid and Bases Remedy the Body?
Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.
Curated OER
Air, Air Everywhere! Lesson 2: Acid Rain
Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although...
Curated OER
Acid-Base Titration
Students determine the concentration of an unknown solution. This task assesses students' abilities to state hypothesis, develop procedures for investigation, plan for recording and organizing observations and data, collect data, create...
Curated OER
Bridging the Gaps Between the Three Worlds of Chemistry
Students examine the observed world, molecular world, and the symbolic world of chemistry. They observe a demonstration of the conductivity of solutions, describe the properties of acids and bases, and predict the outcome of solution...
NOAA
Off Base
How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...
Curated OER
CLEAN AIR ACT (1990)
Students investigate the effects of acid rain by conducting an experiment with bean sprouts and graph the results. In this Environmental Policy lesson, students visit a museum to identify examples of foreign and domestic policy on...
Curated OER
Measuring pH
Pupils perform an experiment which will illustrate how to measure the approximate pH of chemicals in water using a pH indicator. They understand that a pH indicator is a chemical that changes color when it comes in contact with acids or...
Curated OER
Sense of Scale
Students examine the pH scale. They research common products and determine their pH level. They create their own pH scale and place their products in the appropriate place.
Curated OER
Titration and Molarity
Students investigate the concept of molarity and its relationship to the concentration of a solution. After mixing chemical solutions, they calculate how many moles of acid and base should be in each solution. They record their results...
Curated OER
DNA Isolation from Onion
Students apply measurement skills using the metric system. They explain the process of isolating DNA from other cell contents. They apply knowledge of cell structure to explain the process of isolating DNA.
Curated OER
Electroplating for Corrosion Protection: Redox in Action
Learners define what a redox reaction is. In this chemistry activity, students electroplate some wires in the lab. They research the application of electroplating in the real world.
Curated OER
Investigating the Soil
Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...
