| Title | pH Scale inquiry-based intro to acid-base |
| Description | This is an inquiry based activity to introduce pH. The lessons can be used with the Java or html5 sim. I plan to write a quantative activity soon. Learning goals: Determine if a solution is acidic or basic using pH; H3O+/OH- ratio (molecular size representation of just the ions in the water equilibrium);Hydronium/Hydroxide concentration 2.Relate liquid color to pH. 3.Predict if dilution and volume will increase, decrease or not change the pH 4.Organize a list of liquids in terms of acid or base strength in relative order with supporting evidence. 5.Write the water equilibrium expression. Describe how the water equilibrium varies with pH. |

Very good activity. I especially like the post lab quiz and I am going to use it for an assessment.

very good activity, the best thing is going in depth beyond the text book to extend the knowledge . I used it for Gr6.

Glad to hear you find it useful. It is very interesting that your 6th graders were able to use the activity. I will add MS to the categories.
