In this acid and base equilibrium worksheet, students calculate the pH of given acid and base problems using different starting materials. They are given information and hints as to how to work with acid/base equilibrium problems.

Ninth graders study and identify the six major drainage systems in Pennsylvania.  For this watershed lesson students read an article, complete an activity and take a quiz on what they learned. 

Students experiment to determine the difference between an acid and a base. They study the concept of adding a buffering agent to make an acid more basic. They study the pH scale.

Students investigate the pigments in Magic Markers using chromatography. In this paper chromatography lesson plan, students use absorbent paper and mark the strip with a Magic Marker. They place the strip in a solvent and observe the...

At some point, all science learners experiment with pH. For this brief lesson, they simply use pH strips or a meter to find the pH of six different solutions. A useful worksheet that displays a data chart is included for your students.

Students research the effects of soil erosion and pollution in the soil.

Students use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. In this water pollution lesson, students work in groups with stream trays that have different substrates. They write a paragraph...

In this acid and base equilibrium worksheet, students calculate the pH of various types of acids and bases. They are given directions and review information as to how to complete these problems.

Students review the basic lab techniques by following lab procedures. They analyze data by using raw data gathered. Students comprehend the processes occurring inside the column. They use specific chemicals to help determine the...

Learners explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.
