Reflection: Flexibility Acid /Base Demonstration - Section 3: Student Activity


I'm torn about using simulation software for science instruction. On one hand they are a cost effective method for delivering content and on the other hand they rob the students of a kinesthetic laboratory activity.  

I use an informal set of criteria to determine whether I should use a simulation:

  1. The activity materials are too costly for all groups in all classes to perform.
  2. The materials are too dangerous for students to work with.
  3. I have a very limited amount of time to spend on this topic and the simulation buys me valuable time.
  4. The lesson content is not expressly covered by instructional standards.

I never select to use a simulation because it is just easier to do. I feel that students should be given every opportunity to manipulate scientific instruments, but I also understand the demands of teaching. It comes down to your professional judgement.

Acid /Base Demonstration

Unit 9: Solutions
Lesson 3 of 3

Objective: Students will be able to see the various pH values of eleven different solutions.

Big Idea: Demonstrating the different pH solutions to different solutions gives the students an opportunity to understand that all solutions have a pH that is either acidic, basic, or neutral.
