natural bath sponge (or image of one). Introduce the idea that the sponge is what remains of the insides of an organism. Ask students if they think it’s a plant or an animal or neither. Ask students to list some features that they would find out more about, in order to be certain whether it was a plant or an animal or whether it belonged to some other kingdom (fungi, protists, bacteria). between the characteristics, and these groups are called kingdoms. classifications. Ensure that students understand that the closer a group is to the genus or species grouping, the more closely related the organisms will be and the more similar their DNA will be. Point out that in the past scientists looked at the characteristics that they could see, but today classification is usually done according to how similar the DNA is. Digital: Classification of kingdoms and domains presentation CB4d Breeds and varieties B4.8 B4.10 Explain selective breeding and its impact on food plants and domesticated animals. Describe genetic engineering as a process which involves modifying the genome of an organism to introduce desirable characteristics. 1) Challenge students to produce a list of useful characteristics for cattle on a UK farm (e.g. good meat, quick growing, produce a lot of milk, docile). Then ask what other characteristics might be useful for cattle being farmed in northern The practical measures the amounts of citric acid in different varieties of the same citrus fruit, which is an important factor for breeders. 1 cm3 of 0.1 mol dm−3 sodium hydroxide will neutralise 0.0064 g of citric acid.
