18.02.10: Loops, Le Chatelier and Diffraction

This week we've got three more new simulation-based lessons for you to try with Yenka.  If you've not already got the Yenka products we've used to make them, you can get a free licence to try out the content.

Programming Loops

Made with Yenka Computing - (Sequences)

In this model, you can learn about programming loops by controlling a dancing boy. Arrange flowchart commands to make him complete a looped sequence of dance moves - and then choose your own dance steps to customise the routine!

We created this with Yenka Sequences - which is completely free to use in school, as well as at home.

Le Chatelier's Principle - Temperature

Made with Yenka Science - (Inorganic Chemistry)

In this simulation, you can apply Le Chatelier's principle to the equilibrium reaction of ammonium chloride. Change the temperature of the reaction and observe the changes in the volume of gases to deduce whether the forward or reverse reaction is endothermic.

Wavelength and Diffraction

Made with Yenka Science - (Light and Sound)

In this model, a radio transmitter is broadcasting a signal which is being detected by a hut on the other side of a hill. By changing the wavelength of the signal, you'll find that it can be diffracted around the hill so that the signal is stronger at the hut.
