UNIT

This lesson looks at using key terms to describe different organisms within a food web and interpreting food webs.

Food Chains and Webs

This lesson looks at representing food chains as pyramids of numbers and pyramids of biomass.

Representing Food Chains

This lesson looks at the causes of decay and why it's so important. We then look at the conditions required for decay and how a compost bin is designed to increase the rate of decay.

Decay

This lesson looks at how changes in the environment can affect different organisms within a food web, including the process of bioaccumulation.

Impacts on Food Webs

This lesson looks at using quadrats to carry out random sampling, how to write a method and calculating means.

Random Sampling

This lesson follows on from the previous lesson by completing frequency tables, calculating areas of compound shapes and estimating populations of organisms.

Estimating Populations

This lesson looks at what classification is, how we classify organisms using the Linnaean System and how animals are classified into the five chordate groups.

Classifying Living Organisms

This lesson looks at resources that organisms compete for, how they are adapted to their environment and why their adaptations help them to survive.

Adaptation

This lesson looks at what a species is, how variation leads to natural selection and how Charles Darwin's theory came about.

Natural Selection

This lesson looks at evidence behind evolution such a fossils and anatomy and then looks at why some organisms have become extinct or are at risk of extinction.

Evolution Evidence

This look lesson looks at the story of Mary Anning, an English fossil collector who became known for the discoveries she made in Jurassic marine fossil beds in the cliffs along the English Channel.

Case Study of Mary Anning

This lesson looks at the importance of biodiversity and methods being employed to maintain biodiversity.

Biodiversity

In this lesson we recap lessons 1 - 6 including food chains and webs, pyramid of numbers, bioaccumulation and estimating populations using quadrats.

Revision (Part 1)

In this lesson we recap lessons 7 - 12 including classification, adaptations, natural selection, evolution and biodiversity.
