Turn the globe to see how much daylight there is at different places. Then change to another time of year and see the difference. Settling sand Turn the disc and watch what happens to the sand grains. The largest grains settle first while the finest stay suspended in the liquid longer. Layers of 'sandstone' rock often form with finer grains at the top and coarse grains below.
Sand dunes Watch how the fan makes dunes, pits, and sandstorms in the desert sand.
Microscope Look at your own skin, and other samples under the microscope. You can alter the focus by turning the black knob on the side of the lens. The magnified image is displayed in full colour on the screen. The map shows which parts of the world are in darkness and which ones have daylight. Use it to find what time the sun's going to set tonight.
