Teachers’ notes

Safety issues

Care should be taken to avoid touching the bulb whilst it is hot.

Target age groups

Ages 14 - 19 (Science Key Stage levels 4 and 5).

National curriculum

Whilst to some extent this can relate to GCSE level, the calculations involved require some knowledge of Specific Heat Capacity and Heat Capacity so may well be better placed post-16. The activity involves the use of a 12 W bulb placed inside a box and the voltage applied to the bulb, the temperature of the box and the light level all being measured. KS4 Sc4 Physical processes. Energy resources and energy transfer. Energy transfer. 5b about the efficient use of energy, the need for economical use of energy resources, and the environmental implications of generating energy.

Testimonials

  • I have been using my 4224 PicoScope for years. I travel abroad so this has been ideal due to its physical size. Storage of waveforms on my Laptop is very easy allowing me to quickly email waveforms to my Colleagues.

  • Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. This made my decision much easier when I was looking to buy an USB scope.

    Raul Trifan
  • We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations.

    J Mohanty
  • PicoLog TC-08: This is a very nice unit that works consistently and reliably.

    Jeff Hulett
  • It is a great scope. I had a weird problem - it did not work on one of my PC’s. Customer service gave me first class service. If I could give 6 stars for customer service - I would do so.

    Niels Larsen
  • Perfect Partner for Development of Encoder controlled Stepper Motor Actuators. Since the included software is really stable, this type of device is a great tool for great tasks!

    Helmut Schoettner
  • A superb piece of equipment worth its weight in gold

    Nigel Clinch
  • So simple to use & beats any other I have ever used hands down.

    John D Samsing
  • Great functionality in a compact size. I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. Calibration equipment is a breeze with that feature.
