Resources for Practical Experiments
The practical experiments chosen for exemplars are all based on experiments commonly used in school and university education. A number of principles have been adopted in their production.

• A recognition that simulations sh ould not replace real practical experience only augment it. We have focussed on the underlying learning outcomes required from the practical rather than attempt to mimic the experience.
• Typical sources of error such as timing errors are included.
• True relative time: Where events occur in an experiment, the relative time taken is accurate where possible is the time it would take in the real experiment.
• Students have a choice over which data to plot on which axes.
• Students are given choice in data presentation and are able to configure graphs, choosing axis labels and units and to define maximum and minimum on the axes.

There are 4 different practical exemplars. Each is available in a generic form and in a form which reflects the house style of the originator of example. It takes some time to complete the experiments and for non-chemists and those who just want a quick look, the visualisations are also provided with the experiments completed. Links to the various exemplars are below.

1. The Effect of Concentration Changes on Reaction Rate
   (Level:Equivalent to Scottish Higher)
2. The Effect of Temperature Changes on Reaction Rate
   (Level: Equivalent to Scottish Higher)
3. Kinetics of the Acid-CatalysedPropanone/Iodine Reaction
   (Level: Equivalent to Scottish Advanced Higher and A/S level)
4. The Halogenation of Acetone
   (Level:First/second year University)
