1) Welcome

I stamped Unit 7 Wk 3 in class. I also handed out a letter regarding our tie-dye lab in May. 
I am asking for a $2.00 donation to cover the cost of all Materials. we will do this lab at the end of May.


2) Classwork
Get out your Unit 7 Wk 4. We are going over energy transfers in reactions: 
I used a powerpoint and you need to take notes directly on your Unit 7 WK 4.
I posted the powerpoint (Energy in Reaction) and a lecture online for these problems!!!!

Exothermic energy is released to the outside.....We may add a little energy to start but once started 
the reaction releases MASSIVE amount of energy....Think COMBUSTION.
Endothermic reactions require energy goes in....We need to add heat continually or the reaction stops.

We did problems 1 and 2 in class. See powerpoint Energy in Reactions

3) Homework: I posted the powerpoint and a lecture online for these problems!!!!
Finish Unit 7 WK 4 Problems 3-5 are due Monday 4/3/17
Unit 7 Objectives nd Review are due Tuesday 4/4/17
