Measuring Planck's Constant Exp 1: Photoelectric Effect Planck's constant with data from the documentation

 This experiment didn´t work  The beam was not aligned  The operational amplifier didn´t work correctly  It seems nobody has done measurements since last year  When touching wires the measurements change  Not appropriate for our students Exp 1: Photoelectric Effect

Exp 2: Fine Beam Tube

Exp 3: Electron Diffraction Tube

Exp 4: Cathode Ray Tube

 Guide for students  Guide for teachers  Guide for technicians Exp 4: Cathode Ray Tube

Guide for students Exp 4: Cathode Ray Tube

Guide for teachers Exp 4: Cathode Ray Tube

Guide for technicians Exp 4: Cathode Ray Tube

Guide for students translated into Spanish

Exp 5: Electron Spin Resonance

Aims  To reorganize the Teachers Lab  To have a hands on experience of the experiments  Proposals for gifted students

An international experience for high school students (16-17 yrs)

Teachers´ Lab a friendly place

Teachers´ Lab a place to invent new experiments in Modern Physics

Conclusions  The proposed experiments require continuous maintenance  It is necessary to re-think and re-write the documentation of all the experiments  It would be great to find new experiments less expensive  A Teachers´ Lab in the Microcosmos Exhibition requires someone to supervise, maintain and explain the experiments
