Using Reinventing Science Kits in the Science Fair
Reinventing Science Kits are designed to work not only in the classroom or lab, but also as science fair experiments.  Individual versions of the kits contain instructions that help guide parents and students along the process of forming a hypothesis, testing it, gathering data, analyzing the data, and then deciding if the data confirms or disproves their hypothesis.  Simple experiments are possible for lower grade levels all the way up to high school level with intensive data logging and detailed experiments.  Don't worry though teachers, we don't give students any answers or prompt them too much on the methods they should use.  Instead we give advice, safety information, and some examples to work from. 

Below are some examples of the kinds of science fair topics that can be attempted with our Reinventing Science kits.
 

Reinventing Edison: Build your own Light Bulb
  • Effects of Vacuum vs. No Vacuum on Bulb Life
  • Effects of Filament Material on Bulb Life
  • Effects of Filament Length on Bulb Brightness
  • Effects of Filament Diameter on Bulb Brightness
  • Effects of voltage level on Bulb Life or Bulb Brightness
  • Brightness of various filament materials
  • Emission spectra of various filament materials
  • Ohm's Law with a Light Bulb
  • Effects of Temperature on Filament Resistance and Current
  • Effects of low voltage A.C. current in all above experiments
  • Build a Light Meter to measure light emitted from the bulb.
  • Compare your home made bulb to a store bought bulb
  • Effects of Helium as an inert gas on bulb life/performance
  • Historical research into light bulb development
  • Other alternatives to incandescent bulbs (LED's, Fluorescent, etc)

 
 

Reinventing Morse: Build your own Telegraph
  • Effect of wire length on magnetic field strength
  • Effect of wire diameter on magnetic field strength
  • Effect of wire type on magnetic field strength
  • Ohm's law and an electromagnet
  • Effect of Voltage level on magnetic field strength
  • How a communications system works (key, relay, sounder)
  • Longest distance you can transmit a message
  • Building an ultra-low-voltage relay
  • Measuring magnetic field strength
  • How a buzzer works
  • Creating an encoding system, your own Morse Code
