It is a powerful and easy simulator that lets you model different models in electricity, motion and forces, optics and waves.
Crocodile Physics is ideal for use either on whiteboards or by individual students.
To set up simulations, simply drag parts from the toolbars at the side of the screen, and move or position them as you wish; they start simulating straight away. Click on them to edit settings, and plot graphs to analyze data from your experiment.
 Crocodile physics let you experiment electricity, as it contain a full range of electrical components from the basic batteries, bulbs and switches - which are also given in pictorial form, to help understanding of the first principles - to more advanced logic gates, integrated circuits and semiconductors.
A vast component library gives you the freedom to experiment in a way that suits your teaching, and allows interested students to explore the subject more deeply.
Creating circuits is simple. Just use the mouse to drag components onto the screen, and then link them by drawing wires between their terminals. As you draw, the animation shows the design springing to life.
The simulation is mathematically accurate, allowing you to test designs and explore the laws of Physics. Most component values can be changed as will.

Motion and Forces
Crocodile Physics lets you experiment freely with forces and motion, with control over a wide range of parameters. Add balls, blocks and carts, position them as you wish, and drop, accelerate or collide them. Define parameters like mass, elasticity, coefficient of friction, dimensions, velocity and driving force, and add your own images to give context.
Attach rods and springs to investigate simple pendulums, spring oscillations, Hooke's Law and rotational motion.
Slopes and grounds add gravity to your simulations - you can set the strength of this field, and also the elasticity and friction of the ground.
The Graph part lets you follow the motion of your parts. You can plot many quantities against time or against other part properties.
Optics in Crocodile Physics
Crocodile Physics includes a powerful optics simulator, with a range of components including lenses, prisms, mirrors and light sources.
You can import your own images and investigate how they look when viewed in lenses in mirrors. As shown below, intensity and blurring are modeled.

 It is an easy to use simulated chemistry laboratory where you can model experiments and reactions safely. Crocodile Chemistry is ideal for use on whiteboards, as well as by individual students.
Drag chemicals, equipment and glassware from the toolbars at the side of the screen, and combine them as you wish. Choose whatever quantities and concentrations you like: reactions are modeled accurately as soon as you mix the chemicals. Plot graphs to analyze data from your experiments, and view mechanisms using 3D animations.

 Crocodile Mathematics is user-friendly mathematical modeling software for secondary school geometry and numeracy.
Mathematical modeling is made simple - link shapes, numbers, equations and graphs to create your models.
Features: Shapes in Crocodile Mathematics
Shapes are the basic building blocks in Crocodile Mathematics. You can use them to build a wide range of models.
They range from lines, circles and arcs, through triangles and squares, to regular and irregular polygons where you choose how many sides you want.
Once on your screen, all shapes can be resized and rotated. You can also include equations, numbers and graphs in your model.
Making Relations Between Parts
Crocodile Mathematics allows you to link shapes' properties to one another by defining a relation between them.
When you move or resize with shapes that have connections, the shapes that they are connected to will also be affected.
Simple connections can be used to create models demonstrating many laws and theories, such as Pythagoras' Theorem and trigonometry.
 Most of the shapes in Crocodile Mathematics can be transformed easily - including rotations, reflections, enlargements and translations.
If you move or resize the shape, the transformed shape will show this as you work. You can also click on the transformed shapes, to work with them or to apply further transformations.
You can also drag centre of a rotation or the axis of a reflection on-screen, allowing you to visually define the exact transform or combination of transforms you want
The Graph Tool
Crocodile Mathematics has a graph tool, which allows you to quickly draw graphs on-screen, and edit their parameters easily.
It lets you use plot functions just as you would with a graphic calculator - but with an easy-to-use interface and a flexible, clear display.
You can plot a wide range of functions, from lines and parabolas to exponential, trigonometric and hyperbolic curves.

 Crocodile ICT is a powerful tool for teaching control and programming. A simple flowchart interface lets students write sequences of instructions to control either human characters or on-screen animations, making complex programming concepts easily accessible to all.
Each character has many actions - dance steps, movements and interactions - which you control. Link as many as you wish, in any order - so each student creates their own sequence.
The characters engage all students - whether or not they're already interested in programming and control.
You can start with simple routines, and move on to cover more complex topics, including loops - using variables to count repeated instructions - and functions, with or without parameters.

These Yenka products cover design and technology, and systems and control. If you're using more than one of them, they work seamlessly together - sharing one user interface; if you use all of them, they will cover the topics found in Crocodile Technology fully.
Yenka Electronics:
Yenka Electronics lets you design and simulate circuits using over 150 types of component, testing and refining your design as you work.
Yenka Gears:
Yenka Gears lets you experiment with a range of mechanical components, in full 3D.
Yenka PCBs:
Yenka PCBs is an add-on for Yenka Electronics. It takes the 2D circuits you simulate, and converts them automatically into three-dimensional PCB simulations, which can be exported for manufacture.
Yenka PICs:
Yenka PICs lets you write routines using simple flowcharts, and test them on-screen, before using them to program real PIC or PICAXE chips.
Yenka Mathematical Product
Yenka 3D Shapes are a new modeling tool for experimenting with 3D geometry.
Start by dragging ready-made shapes or nets onto the screen, then resize or rotate them by dragging.
Simple tools change the 3D view and change colors and textures. Add questions, instructions or text - and create your own custom-made lessons.

What’s Bunja?
Bunja is a new interactive audio toy designed for children aged 6-11 to help improve math skills with an exciting interactive adventure story.
As you answer questions, bunja learns about you and adapts to your ability. You are rewarded with new adventures where you need to help Sam, who's lost in the jungle, by choosing what to do. It covers 100 adaptive math’s topics and 80 interactive adventures. 
Bunja Features:
- It covers 100 adaptive math’s topics
- 80 interactive adventures
- Audio only - improves listening
- MP3-quality audio - headphones optional
- Keeps track of your progress
- Up to 10 different players
Game
- The game has 16 stages, with 5 adventures in each stage. If Sam is captured during an adventure, you have to go back to the start of that stage.
- Skip through the story by holding down the A button until you hear the second beep. This skips ahead to the next question. It's very handy if you have to redo an adventure because Sam was captured! But, don't try this when helping Sam (answering a question) or it will select the A option!
- Replay Sam's current description by holding down the B button until you hear the second beep.
- If you don't choose an option, the question and answers will be repeated.
- Listen carefully to Sam's descriptions of what is going on. Sam hints at what options are more likely to succeed.
- The same choice won't always give the same result. You have to be clever and lucky to succeed!
Math
- To hear the question and answers again, simply don't choose an answer and they will be repeated.
- You are given two tries to answer a question correctly.
- There's a hidden shortcut to the Fixed Topic Menu! Instead of just pressing the i button, hold it down. This gives you a menu where you can input a new topic number or listen to reports on the current fixed topic.
