Activity 8: Exploration of Chemistry Simulations

Activity 8: Exploration of Chemistry Simulations (and last Activity!)

For activity 8, students have a choice to explore other topics of chemistry presented in the PhET simulations.

Tasks to be completed:

1. Choose any Teaching Idea from any of the Chemistry Simulations (http://phet.colorado.edu/en/simulations/category/chemistry ) and post your results/data and/or answers on your blog.

2. Work with any of the Chemistry Simulations to create your own Teaching Idea. The criteria for this is as follows:

a. must identify and meet three (3) science education standards

b. must be original work

c. must be scientifically accurate and appropriate for the directed grade level.

Activity 7: Acids and Bases

Activity 7: Acids and Bases

Water is everywhere! So, lets spend one more activity learning about one of the key aspects of water. Water has the ability to dissociate (break apart from HOH (or H₂O) into H+ ions and OH- ions). We refer to solutions with lots of H+ ions as acids and solutions with lots of OH- ions as bases. By adding chemicals with H+ ions acidic solutions can be made. By adding chemicals with OH- ions basic solutions can be made.

Activity Tasks:

1. Review the Content Slides Acids and Bases on the D2L site.

2. Complete the Teaching Idea “Concept Questions for Chemistry using PhET” posted by Trish Loeblein on the pH Scale simulation at PHET (http://phet.colorado.edu/en/simulation/ph-scale). On your blog post the answers with your scientific explanations from the “Clicker Questions pH Scale” posted by Trish.

3. Complete the Teaching Idea “Intro to Strong and Weak Acids and Bases” posted by Chris Bires on the Acid-Base Solutions simulation (http://phet.colorado.edu/en/simulation/acid-base-solutions) and post on your blog your data and answers to the questions posed.
