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

Page 4: Scientific Method

1900- 1945 (Prior to WW 2)

Electricity (outlets and lights)

Few women Some small

appliances (blender)

No computers

Page 5: Scientific Method

Laboratory 1945-1965 Fluorescent

lighting Glassware

and instruments are more compact

Still prefer wooden furniture but some metal and plastic is used

Page 6: Scientific Method

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

Page 7: Scientific Method

1985-1995

Computers present

Instruments present

Digital balances

Ventilation and safety devices in plenty

Much area for electronics to plug in

Page 8: Scientific Method

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.
