Used to separate a liquid from a soluble solid. Eg Water from Salt. The water is heated and evaporated into the surroundings, leaving the salt behind in the evaporating dish.

Used to separate a mixture of soluble Inks/Dyes. The ink gets drawn up through the chromatography paper. Ink that is most soluble in the water will move the furthest up the paper. A pencil origin line is used as pencil will not dissolve in water.

Used to separate a mixture of soluble solid and a liquid. However, the liquid can be kept and not lost to the surroundings. Eg. Separating water from salty sea water. First the water is evaporated as steam by heating it, leaving the salt behind, then it is condensed and cooled back down into liquid water.

Animals and plants rely on each other survival.

Plants use light energy from the Sun to produce food by Photosynthesis – Plants are Producers

Animals eat plants for food. Other animals can eat these animals for food too. Animals are Consumers.

This transfer of chemical energy from plants to animals is called the food chain.

Living things are put into two main groups: Animals & Plants

Animals have 2 main groups:

• Vertebrates - Animals with Backbones, table shows the 5 groups

• Invertebrates - Animals without backbones, like the ones below.
