We then moved onto the overview for our next assignment: creating an experiment to investigate either how the chemicals in a famous reaction change from before to after the reaction (mainly by comparing either mass or temperature,) or by comparing how changing something about the reaction can change the outcome...like, does changing the temperature change the amount of "fizz?"
By they way, the reaction in question is the simple gas producing reaction of an acid mixed with sodium bicarbonate/baking soda.
As of Thursday, people with approved hypotheses, with properly identified variables and procedures will be able to start. All experimentation and data gathering must be done by Monday, and the full project will be due on Thursday of next week. No more than two people may work together, and everyone must submit a full complete project, regardless of whether they worked with anyone else.
In social studies, we read through and took some time working on the responses for the Madison, Marbury, Monroe and Quincy handout. Please remember that those responses are due Thursday. (Homerooms 164 and 167 must complete 1-6 in CARs format, and 166 must complete 1-6 in short answer format.
To be helpful, I'll post the PowerPoint with the outline of the in-class experiment below.
For those who are going to Springfield tomorrow: be sure to wear your shirt and to show up at 5:45 pm! For those of you who are not going...well, we won't be doing too much. Bring a book! (Or stay home...)
