Last class period to collect data for Internal Assessment.  Remember that your IA consisting of the Design and Data Collection and Processing is due next Tuesday, March 4th.

If you still need to finish your trials, you will need to come in before or after school (check with me to make sure I’ll be there!).

Topic 5/15 Study Guide- make sure to look at the assessment statements as well:  Energetice study guide

Vocabulary for this topic:  Energetics 1 VOCAB

Equations for this topic:  Energetics Equations

Day one to carry out designs.  Remember the entire Internal Assessment (Design and Data Collection and Processing) is due next Tuesday, March 4th.

1. Warm-up:

a.  Describe some ways to minimize errors associated with these methods.  

2. Lab:  Heats of Solutions and Reactions  LabHeatsSolutionandReaction

*there is no formal write-up for this.  I want to see your calculations and resulting changes in enthalpy for each reaction and your answer as to if the reaction is exothermic or endothermic.
