  pH, Acid & Base Theories | High School

  Lesson Plan: Development of the Beckman pH Meter Mark as Favorite (1 Favorite)

  In this lesson, students will learn about the development of Arnold Beckman’s pH meter, as well as related topics in the subject of acids and bases through reading an article and engaging in related activities. The activities help promote literacy in the science classroom. Parts of this lesson could be used as plans for a substitute teacher.

  Chemistry Basics, Identifying an Unknown, Solutions, Solubility, States of Matter, Melting Point, Phase Changes, pH, Strong vs Weak, Observations, Molecular Motion | High School

  Activity: Simulation Activity: Identifying Unknowns with Safety Data Sheets Mark as Favorite (19 Favorites)

  In this activity, students will use a simulation to learn about some of the sections of a safety data sheet (SDS) and how the information on SDSs can be used not only for safety purposes but also for identifying unknowns. Specifically, students will use “Section 9: Physical and Chemical Properties” to distinguish between two or three substances with similar appearances in a variety of lab-based scenarios. Particle diagrams are also included to help students visualize the substances’ behavior on a particulate level.

  Demonstration: Inflating a Balloon with Chemistry Mark as Favorite (29 Favorites)

  In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.

  Freezing Point, Melting Point, Phase Changes, Physical Change | Middle School

  Lesson Plan: Stearic Acid Mark as Favorite (2 Favorites)

  In this lesson, students investigate how stearic acid undergoes a phase change from solid to liquid and back from liquid to solid. Temperature readings will be collected at one-minute intervals once the acid melts, the heat escapes, and the acid cools. Students are introduced to the idea that energy loss does not always result in a continuous temperature drop.
