States of Matter
Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to boil water through...
Curated OER
A Plop and Fizz
Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry lesson, 7th graders take measurements and record data. They create a graph and analyze results.
Curated OER
Determining pH
Eighth graders explain the difference between acids, bases and neutral solutions. In this chemistry lesson, 8th graders describe the properties of each. They determine the pH of an unknown solution using the indicator paper and pH scale.
Curated OER
Acids, Bases, Acid-Base Reactions
In this chemistry worksheet, students read and study the chapter to answer 110 problem solving and short answer questions related to acids and bases.
