1 Daily Science (pg. 4) Go through the bucket on your station and see how many things you can identify.

2 Lab Map (page 7) Sketch a map of the lab and label the following: First aid kit Fire extinguisher Fire blanket Cabinets (volumetric flasks, funnels, graduated cylinders, beakers, Erlenmeyer flasks) Sinks/ gas outlets Aprons Goggles Broken glass box Eye wash

3 Mechanics of measurement (pg. 9) Science is only as good as the instrument that measures it

4 Accuracy vs. Precision Accuracy- how close you are to the true measurement. Precision- how close your measurements are to each other.

5 How to read a scaled device Step 1: Determine the intervals used on the scale. (Is it counting by ones, tens, fives, etc.?) Step 2: Record the measurement and then record one more number. The last number is always uncertain, but its in the ball park Recording Measurement Worksheet

6 How would you read this? 1. What is it counting by? 2. What it the measurement? 3. What is the uncertainty number? Ones

7 Graduated cylinder Read at the bottom of the meniscus Always read the bottom of the meniscus at eye level.
