Scientific Method, Metric System, REVIEW: Scientific Method, Metric System, & Lab Safety

STEPS OF THE SCIENTIFIC METHOD: State the Problem Gather Information Form Hypothesis Design an Experiment Record/ Analyze Data Draw Conclusions Repeat (if necessary)

SCIENTIFIC METHOD VOCAB: Control: Constant: Independent Variable: Dependent Variable:

METRIC SYSTEM: Universal System of Measurement Volume: Liters (L) Mass: Grams (g) Length: Meters (m) Temperature: Celsius (C) or Kelvin (K) Prefixes: Kilo Hecta Deka BASE UNIT Deci Centi Milli *If you move from left to right (going to smaller units), you will multiply by 10 each time *If you move from right to left (going to bigger units), you will divide by 10 each time

1. Write what you know over 1 CONVERSIONS: 1. Write what you know over 1 Find conversion factor– write it in correct order Cancel out units Repeat as necessary Multiply/ divide Ex. How many seconds are in 1 year? 1 year X 365 days X 24 hours X 60 min. X 60 sec. = 31,536,000 sec. 1 1 year 1 day 1 hour 1 min.

Lab Safety: What are some things that you know about working in a laboratory? What are some of the pieces of equipment that you know?

Now, for the tour of the lab...
