Today we modeled the decomposition of hydrogen peroxide into water and oxygen. We did this using the molecule sets and the instructions to the start up activity (found on page 27). If you missed this in class you can try it at home using marshmallows and toothpicks.
We also graded our chapter one homework, turned in our commercials, and found out our grades on the model. We took a few notes on products, reactants, the yields symbol and conservation of matter. We also discussed the difference between coefficients and subscripts in chemical formulae--and we counted the number of atoms in compounds.
Finally, we received the new take twenty homework handout--the first ten points will be due the 15th/16th, the second ten points will be due the 22nd/23rd.
Finally--we found out that the plasma ball can activate the musical chip in my holiday tie!
