Coil circuit (contracted)
by RnibThis image shows how a coil circuit works. In the centre of the image is a large rectangle. To the left of this is a small circuit containing a power supply and a switch. This enters the rectangle and coils around a soft iron core. To the right of the rectangle there is another circuit, this one has a mains power supply and a large industrial machine. This circuit also enters the rectangle ending in two contacts. Within the rectangle, both circuits are separated by a textured shape labelled iron.
Colour reflection/transmission (contracted)
by RnibA diagram showing how light reacts when hitting colour surfaces. There are two example in this image. The top diagram shows light hitting a yellow book and being reflected as green and red light. The second diagram shows light passing through a magenta filter and turning into red and green light.

Common horsetail (large print)
by RnibThis is an image of a Common horsetail: Equisetum arvense.There is a locator dot shown, which will be at the top left of the page when the image is the correct way up.The horsetail's rhizome (underground stem) is at the bottom of the page. There are thin roots branching down from it, and on its right four small, round tubers.Curving up from the left of the rhizome is a brown fertile stem. Like the rest of the plant there are several nodes along its length. At the top of this stem is a strobilus, a structure carrying the sporangia, which produce spores. Here they are represented by many small dots.To the right of the fertile stem is a young shoot and branching off to the right of this, going vertically up the page is a non-fertile green stem. This has branches off to the left and right of the stem. On a real plant there would be many more branches, up to ten in each group, but for clarity only four in each group have been shown here.The horsetail is a primitive plant and does not have flowers or seeds. It can grow up to 30 centimetres high.

Comparing circuits (contracted)
by RnibThis is a labelled diagram of an experimental set-up to compare the rate of heat conduction of three materials. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. At the top of the page are three wax-tipped rods going horizontally across the top of the page. Each rod is has a blob of wax on its tip on the right of the page and each has the same dimensions (length and thickness). The rods are labelled to the right with a letter. The rods are being heated by a bunsen burner in the bottom left of the page. It is important that the left hand ends of the rods are all at the same distance from the heat source. The heat energy travels to the blobs of wax on the right of the rods and the wax on the most heat-conductive rod melts first.
