Summary:
We’ve covered several difficult topics in the past few lessons. For the next three days, we’ll simply practice. It will be a three-day lab called “Where’s the Evidence?” where students will be looking for evidence of chemical reactions. And each day will follow the same format: students will begin with a few pre-lab questions, then do the the experiment, then complete the post-lab assignments for homework.

The first day’s experiment involved mixing hydrochloric acid and sodium carbonate. The reaction bubbled and produced heat. And it left behind three new compounds: water, carbon dioxide, and table salt.
