Crocodile Physics is like a well-stocked physics lab where you can experiment to
             your heart's content. Covering many syllabus topics, here is the hardware flattened for
             the small screen. There are masses, trolleys, lenses and electronic components to
             assemble, experiment and take measurements with. You can swing pendulums, change
             gravity, change angle of ramps to learn about forces. Excellent are the optics tools which
             let you split light into its colours with a prism and see how fibre optics transmit light. A
             section on eye defects, where you increase the focal length of a spectacle lens and see
             what that does to the light rays will make an awesome teaching tool. Though it comes
             with worksheets, those with time to spare can use it to create impressive interactive
             Crocodile Physics has been developed from Crocodile Clips 3, the acclaimed
             High School Physics simulator used in over 35 countries and recommended by
             governments worldwide. It's a simulator for Middle and High school and college physics
             Crocodile Physics includes a powerful optics simulator, with a range of
             components including lenses, prisms, mirrors and light sources.You can set the
             wavelength of the light being emitted from your source, and choose parallel beams,
             diverging beams or rays. You can also set the dimensions of the source.
             Crocodile Physics contains a full range of electrical components. Every school
             subject area is covered: 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. One of
             the key features which marks Crocodile Physics out from other teaching
