Scientific Method Let’s view the video
When was this photo taken? (season/month and year)Record observations to back up your inference.
Late1800s Laboratory • Primitive electricity • No Computer • No instruments • Could see some batteries • Could see telephone • No women
1900- 1945 (Prior to WW 2) • Electricity (outlets and lights) • Few women • Some small appliances (blender) • No computers
Laboratory 1945-1965 • Fluorescent lighting • Glassware and instruments are more compact • Still prefer wooden furniture but some metal and plastic is used
Laboratory space 1965-1985 • Most modern equipment is present • Computers are still not present or are too big for the lab • Instruments are still not as visible • Not as much ventilation but some safety equipment
1985-1995 • Computers present • Instruments present • Digital balances • Ventilation and safety devices in plenty • Much area for electronics to plug in
Modern Day • Flat panel monitors • Many instruments • Much safety equipment and ventilation
What should I look for in a college chemistry lab? • TOYS! • Instruments of all kinds Gas Chromatograph, Liquid Chromatograph, Spectrometers, Mass Spectrometers (very nice), NMR, and biotechnology equipment such as electrophoresis chambers • Minimum digital balances, analytical balances, a few computers running up to date software, and some spectrometer like UV-vis or UV-IR.
