1. Topic: Energy Cost & TransferState the law of ‘conservation of energy’Topic: Evolution & InheritanceWhat are genes & where are they foundTopic: Contact Forces and PressureWhat is the equation to calculate pressure?Topic: Periodic Table & Elements Draw an atom & label the different partsTopic: Respiration & PhotosynthesisDescribe the tests for the different products of respirationChallenge: Suggest some ways to reduce a carbon footprintTopic: Climate & Earth ResourcesWhat is meant by the term ‘Carbon Footprint’?
2. Challenge: Give another example of where this may have occurredTuesday, 09 March 2021Describe what the picture shows. Explain why the taller giraffes are at an advantage. Key word boxPopulation Natural selection Extinct BiodiversityCompetition Evolution Inherited characteristicsDNASuggest what this process is and how it effects living creatures.
3. What is an ecosystem?Each ecosystem can be divided into a:community – the living part, i.e. all the different organisms living in that particular habitat.habitat – the non-living part, i.e. the physical area in which organisms liveEach community is made up of many different populations. A population is all the members of a particular species living in one habitat – for example, the population of red squirrels in an oak wood.The environment is made of many different types of ecosystems, such as seashores, forests, lakes and deserts.

8. Lamarck (1744-1829) was the first person to put forward a theory for evolution – the way organisms change. He suggested that there was “inheritance of acquired characteristics”. For example, if a giraffe was stretching its neck to reach higher branches, its neck would grow and its offspring would have a longer neck.
9. Lamarck’s theory was incorrect. Imagine if you kept on raising your hand in class to answer questions. Your hand would not get any longer.
10. Born in 1809.HMS Beagle set sail in December 1831.Darwin was on the voyage for five years around South America, the bottom of Africa, Australia and New Zealand.He started out looking for rock samples from all the places he visited. Charles Darwin
11. Darwin’s FinchesCharles Darwin was the first person to properly discover evolution by natural selection. He discovered this while looking at finches in the Galapogos Islands.

13. Process by which species change over time in response to environmental changes and competition for resources.https://www.bbc.co.uk/bitesize/clips/z4pd2hvLooking at the Cheetah and Gazelle – What characteristics do you think would be advantageous and be passed on to future generations?
14. Natural SelectionThe differences in a population gives some individuals an advantage. An individual may be more resistant to a disease, or better camouflaged, or stronger, faster or better able to attract a mate. This individual is more likely to survive for longer and be able to breed to pass on desirable genes. Nature is selecting the individual with the phenotypes most suited to survival. This is called natural selection.understanding evolution Mutation, species, genes, variation, phenotype, natural selection
15. What is natural selection?Explain why Darwin’s findings were so importantExplain why having a longer neck might make the giraffe more successful at spotting predators such as lionsCompare and contrast the theories of Darwin and Lamarck
16. Natural selection is how a species evolves over time. The animals or plants that have characteristics that allow them to live longer and reproduce more are inherited by the next generation. The species with characteristics that don’t survive as well don’t get passed on.Antibiotic resistant bacteria
17. Define gene, chromosome and DNA.Describe where we find chromosomes and how many we have. Explain why genes, DNA and chromosomes might be describes as ‘instructions’.Stretch: Suggest what might happen if we all had the same DNA. CHALLENGEYour answer must have one connective, and be 23 words.
18. DNADNA (deoxyribose nucleic acid) molecules are large and complex. They carry the genetic code that determines the characteristics of a living thing.Except for identical twins, each person’s DNA is unique. This is why people can be identified using DNA fingerprinting. DNA can be cut up and separated, forming a sort of 'bar code' that is different from one person to the next.GenesA gene is a short section of DNA. Each gene codes for a specific protein by specifying the order in which amino acids must be joined together.ChromosomesThe cell’s nucleus contains chromosomes made from long DNA molecules.
