An adaptation is a feature that organisms have to help them live in a particular place and survive.

Camouflage is a strategy that organisms use to disguise their appearance, usually by blending in with their surroundings.

Producers make their own food using a series of chemical reactions called photosynthesis.

Adaptations

Science

Fossils show that species change over time

Understanding time scales

Competition

Heritable variation

Natural selection

A model of natural selection

Evolution

Pupils will learn that the fossil record provides evidence of evolution from common ancestors through transitional species to modern species, and that the theory of evolution by natural selection can be used to explain phenotypic changes in populations of species over generations.

Pupils learned that variation (differences in the features of individuals of the same species) can be caused by environmental and genetic factors.

This unit explores variation within and between species, competition, and natural selection. It focuses on asking questions, making predictions, planning scientific enquiries, and testing hypotheses. It also covers analysing results, explaining findings, and identifying new questions that arise.
