We have several Yenka products which cover science. 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 same areas as found in our earlier simulators Crocodile Physics and Crocodile Chemistry.

At home, you can use them all free of charge.
At school, you can buy them individually, but you can also can save money by buying them together, as the "Yenka Science bundle".

If you don't need to teach electronics, you can also buy the Yenka Science Bundle without this product.
