CST Overview

The TEST!!!  There are 60 questions  If you score a Proficient or Advanced you will automatically pass the class (even if you failed 1 st semester)

 CHIE: Investigation and Experimentation Reading graphs, analyzing data, models, theories, scientific method Reading graphs, analyzing data, models, theories, scientific method Lab work!

CHIE  Laboratory equipment, safety  Measurements  Scientific method  Precision (repeatable)  Accuracy (close to correct answer)

Equipment needs to match experiment:

Scientific method & safety

Scientific Method

Graphs  Read all titles and axes  Write on graph when necessary to find answers  Slope = rise/run: pick points far from each other (origin and last point?)  Read all graphs when they are with questions

Models & tables

% composition  Element’s mass x 100 = % Total mass Total mass  What is the % of H in H 2 O?

 Physical changes: No new matter No new matter Phase changes Phase changes  Chemical changes Reaction produces new products Reaction produces new products Hard to reverse Hard to reverse
