Description
Specifications
  • These thermochromic sheets change colour when influenced by changes in temperature, demonstrating a difference in temperatures and providing an exciting way to see thermal mapping changes through colour
  • The sheets can be used from Key Stage 1 all the way through to Key Stage 4 to demonstrate, Conduction, Insulation, Convection, Radiation and Friction, plus many other experiments involving temperature change
  • The sheets are printed on one side with Thermochromic Liquid Crystal, and have a black backing on the other side
  • The colour change of the TLC can be viewed through the clear uncoated side of the sheet
  • The sheets come with a pressure sensitive adhesive backing and the protective release liner can be removed for easy adhesion to a variety of flat services
  • The thermocolour sheets turn from black to red at a given temperature and, as the temperature is increased, pass through the colours of the visible spectrum in sequence before turning black again at a higher temperature
  • The colour changes are reversible and on cooling the colour change sequence is reversed
  • Liquid Crystals are organic chemicals with twisted helical molecular structures, which expand, or contract with increases or decreases in temperature, not unlike a spring
  • The result is different wavelengths of incident light being reflected from the slightly changing structure, which our eyes see as changing colours
  • The sheets can be made in a variety of temperature ranges but the most common temperature used in school science projects is 25℃ and has a 5℃ band‐width of green
  • These sheets can be used in a wide variety of Science experiments
  • Liquid Crystal is highly accurate in its temperature reading and completely safe to use in the classroom
  • The sheet size is 150 mm x 300 mm however you can cut the sheet as most experiments can be conducted using much smaller pieces
