  Titrations, Acid Base Reactions, pH, Equivalence Point | High School

  Activity: Simulation Activity: Acid-Base Titrations Mark as Favorite (3 Favorites)

  In this activity, students will use a simulation to collect titration data to determine the concentration of a strong acid or a strong base. Multiple practice opportunities exist, as each time the simulation is reset, a new value is generated for the unknown concentration. The simulation is not designed to be used in place of the lab technique, but rather as a way of strengthening the skills already learned in the lab.

• 

  Titrations, Strong vs Weak, Acid Base Reactions, pH, Equivalence Point, Equilibrium Constants | High School

  Activity: Simulation Activity: Acid-Base Titrations (AP) Mark as Favorite (5 Favorites)

  In this activity, students will interact with a simulation to practice calculating values from titration data. AP level students select an analyte from a list of weak and strong acids and bases. A pH vs. volume curve is generated using randomized values for the titration, and students use the trace function on the graph to identify the appropriate data points for calculating the concentration and, for weak acids or bases, the value of Ka or Kb, for the selected analyte. The simulation is not designed to be used in place of the lab technique, but rather as a way of strengthening the skills already learned in the lab.

  Titrations, Acid Base Reactions, pH, Strong vs Weak, Equivalence Point, Equilibrium Constants | High School

  Simulation: Acid-Base Titration Mark as Favorite (6 Favorites)

  In this simulation, students can choose to analyze strong or weak acids or bases by titration. From their selections, a pH curve is generated with randomized values.

• 

  pH, Acid & Base Theories | High School

  Lesson Plan: Development of the Beckman pH Meter Mark as Favorite (3 Favorites)

  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 (23 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.

• 

  Chemical Change, Observations, Chemical Change, Mixtures | Elementary School, Middle School, High School

  Demonstration: Inflating a Balloon with Chemistry Mark as Favorite (33 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.
