CHEMISTRY: Here’s the last of our discussion of Dalton’s atomic theory vs. the modern atomic theory. If you weren’t in class today, be sure and get the definitions and applications of allotropes and isotopes. I still say it’s pretty cool that something that was discovered so long ago is something that we use today!
Now on to checking out part of those theories! Today we did Part 1 of the Conservation of Mass lab. If you weren’t in class, you’ll need to make up Part 1 before we do Part 2 in class on Wednesday. You can make it up tomorrow, Tuesday, 5th or 7th periods, or you can come Wednesday morning before school at 7:50 A.M. It will take about 15 minutes. Be sure and read Part 1 of the lab so it will go faster!
