This ONLINE workshop can be logged as Elective Professional Development. The workshop price includes the price of the equipment which the attending teachers get to keep.The included equipment pack will be sent to the attending teachers to be used on the day via Zoom. This includes:

• Red Laser
• Double Slit Slide with 12 double slit sets.
• Spectroscope
• Planck's Constant LED Kit (Included 4 LED's, wires, variable resistor, constant resistor, battery pack, batteries )- (Multimeter not included).

N.B. This online workshop is practical in nature, and requires the use of a laptop with a reliable internet for Zoom. Please have a laptop with Microsoft Excel for data collection and analysis. Teachers begin first by looking at light as a wave,performing Young's Double Slit Experiment to calculate the wavelength of light from the Laser as well as exploring simulations relating to this investigation.

Teachers then explore light as a particle, carrying out multiple experiments on the Photoelectric Effect including using coloured LED's and analysing the data collected on the day. The goal is to find the work function of the Cathode and ultimately find Planck's Constant.

We will then examine the emission spectra of the Hydrogen atom using Spectroscopes and Atomic Energy Level Calculations. Building upon this we will explore how the Redshift of these spectral lines can allow scientists to determine the expansion rate of the Universe known as Hubble's Constant.
