Exploding Soap, Does It Get Any Better?

Thank you students, for some enlightening demonstrations today. (get it? haha. OK, whatever.)  Looking forward to the rest on Thursday.

Now let's try some computer simulations, aka* Gizmos.  Go to: explorelearning.com
In upper right corner, click "login"
At the login page, enter password - jimbridger  and username - jb - click login button.
At class page, click Gizmos.
If the density gizmo loads, then proceed by following the directions on your handout. [If you did loose the handout, you can find it at "Lesson Info.] First, answer the pre-lab questions, then go to the warm-up, and also Activity A.  Then take a break, next day do activities B and C.

If the gizmo does not load correctly, then choose ?Support from the menu bar. Select Troubleshooting
. Then select ExploreLearning Systems Test Page, and run the system test. You may need to install Shockwave Full Version, or enable JavaScript or enable cookies.   (Terry, I made sure your computer would work on Thursday.)  None of these things are difficult, and there is probably someone in your family that can help, although I wouldn't be surprised if some of you  are the computer genius of the family.
You should check with your parents for permission to do this, and if they are reluctant then you may skip the homework.

One last problem, it may be that only one student can log in at a time (?) so try again later.

Lastly, go over your notes from class; add any details you can remember, especially the explanations of density.
