05/03/10: histograms, capacitors and NAND gates
This week, there's another updated tool in Yenka Statistics. The histogram updates live as you edit your dataset, and displays either equal or unequal class intervals. We've also got a couple of electronics lessons for you, for use with Yenka Electricity and Magnetism or Yenka Electronics.
If you've not already got Yenka Statistics, or any of our other Yenka products, you can get a free licence to try out the lessons. You'll need to download the latest version to use the new simulations.
Made with Yenka Mathematics - (Statistics) Yenka Statistics now offers a new histogram tool, which lets you plot data with either equal or unequal class intervals. In this model, a histogram with unequal class intervals displays the
heights of the students in the animated line-up. It lets you understand how frequency density is
used draw a histogram, and use this to work out how many people are over a given height. Use the histogram to check your
answers, and alter the class grouping.
Practise this activity again using a new random sample. Made with Yenka Science - (Electricity and Magnetism)
In this model, a graph shows the change in current as a
capacitor is charged and discharged. Change the position of the switch
in the circuit to charge or discharge the capacitor and watch how this
changes the current flowing through it. Click the capacitor, the battery or the resistor to edit the capacitance, the voltage or the resistance, respectively, and see how it affects the graphs.
Made with Yenka Electronics
In this model, you're challenged to build a circuit using only NAND gates, which will function in the same way as a sample circuit which uses an AND gate, a NOT gate and
an OR gate. There's an introduction to combining logic gates in this model.
Yenka Electronics lets you simulate your own circuits freely, building them up with over 100 types of component - most of which have editable parameters.

25/02/10: new statistics lessons, and electrical power loss
This week we've got some new lessons for teaching maths. We've been adding new tools to Yenka Statistics, to let you experiment easily with graphing and handling data. We've also got a lesson made with our new Electricity and Magnetism simulator.
If you've not already got Yenka Statistics, or any of our other Yenka products, you can get a free licence to try out the lessons.
Made with Yenka Mathematics - (Statistics) Yenka Statistics lets you create and edit datasets easily. As well as typing in data, or importing from spreadsheets like Excel, you can add data by clicking on the scatter graph - each time you click, a new data point is added. When you add a graph to the screen, such as a histogram, it automatically starts graphing your data. Yenka Statistics updates all of the graphs and charts on the screen as you edit data. Click a point, bar or entry in the data table, and the same data point will be highlighted in all of your charts and tables.
Made with Yenka Mathematics - (Statistics)In this model, Yenka lets you enter data for the height and arm span of students in your class - so you can check whether a correlation exists between the two measurements. Yenka Statistics lets you add a line of best fit to your scatter graph. The software will draw the line for you, as well as giving you the type and strength of correlation, and the correlation coefficient. 
Made with Yenka Science - (Electricity and Magnetism)In this model, made with our new 3D electricity simulation, you can experiment with a simple power distribution grid, and learn why higher voltages are better for transmitting electrical power over long distances. Yenka Electricity and Magnetism lets you build your own 3D distribution grids, choosing from a range of power stations and consumers, and setting key parameters like power output, transformer ratio and power line resistance.

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.
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. 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. 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.

New from Yenka: composite shapes, reactivity of electrodes and circular motion
Some more  new whiteboard lessons for you to use 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.
Made with Yenka Science - (Motion)Simulate circular motion using a ball on the end of a rod. Observe the direction of the tension force, and then change the ball's velocity to see the effect this has on the direction of the centripetal force. Made with Yenka Science - (Electrochemistry)Use a voltmeter to measure the voltage across a simulated electrochemical circuit. Change the metal electrodes and look at the resulting voltage to work out the order of reactivity of the metals.  Made with Yenka Mathematics - (3D Shapes)Introducing composite shapes, looking first at composite shape made up of a rectangle and a triangle. You can use the areas of these shapes to calculate the area of the composite shape, and then use Yenka to make your own composite shapes.

New Yenka simulations: 3D PCB casings and maximum component ratings
Today, we've added some new electronic simulations to Yenka.
3D casings
You can now add a casing to your 3D circuit board simulation. When you've done this, you can attach input and output components - such as switches and LEDs - to the surface of the casing, while keeping them linked to the board. They snap to it, and you can position them wherever you want - as we've done with the lights in this traffic light model.  The casings can be made transparent, so you can work on your PCB. You can also make your own custom casings using Google Sketchup, and import them into your model.
Try these simulations to see the casings in action:  Editable component ratingsIn response to many requests, many of our electronic components now have maximum ratings which can be edited. You can now change the maximum voltage for most analogue components. You can also edit other settings, like the maximum current for switches, the maximum power for resistors, the maximum reverse voltage for capacitors and diodes, and so on. Some components have a wider range of editable values - for example, the relay lets you specify the maximum current and voltage for both coil and contact, and transistors let you choose the maximum C/B voltage, C/E voltage and reverse B/E voltage.
Using the simulations
To use these new simulations, you need the latest version of Yenka installed on your computer.
Then just run Yenka, and click the links above to open the casings simulations, or build a circuit to experiment with the component ratings.
