3.8 Know about the effects of food chains in a variety of environments

3.9 Know that changes in the environment have effects on living things

3.10 Know about the nature, functions and effects of microorganisms

3.11 Be able to recognise and name the major plants and animals in the host country

3.12 Be able to classify locally occurring plants and animals according to their features

3.13 Be able to recognise and name the major plants and animals in their home country

3.14 Understand the relationship between living things and the environment in which they live

3.15 Know about the structure of the human body

3.17 Know about similarities and differences between humans and other creatures


You’ll learn about the major subcategories, or taxa, that biologists use to classify organisms. These include: domain, kingdom, phylum, class, order, family, genus, and species. You’ll also see how different animal species are ordered in the tree of life, including all of the kingdom and taxa they belong to. 

Charles Darwin

In this BrainPOP movie, Tim and Moby will introduce you to the life and research of Charles Darwin! You’ll learn about Darwin’s theory of evolution and how it differed from another theory of evolution common at the time.


You’ll learn about what it means for something to go extinct, and you’ll find out about the idea of mass extinction. You’ll also see how changes in the environment sometimes cause certain species to go extinct. In particular, Tim and Moby take time to explain how human activities are causing some species to die out — and how these extinctions can interrupt the food chain and impact entire ecosystems. 

Food Chains

In this BrainPOP movie, Tim and Moby teach you about food chains, the complex webs that connect the eaters...and the eaten.


In this video, Tim & Mody explain the difference between a body fossil, which you might find in a tar pit, and a trace fossil, which might be as simple as a set of footprints. You’ll find out how these amazing relics of the distant past are formed, and why they’re so rare.


Tim and Moby journey through prehistoric times to track the evolution of  dinsoaurs through the Mesozoic Era. From the Triassic Period to the Jurassic and Cretaceous, you'll watch dinosaurs grow in size and diversity.

Human Evolution

This video will teach you about scientists’ current understanding of where humans came from. You’ll discover our relationship to other primates, and learn how the process of evolution by natural selection led to the rise of humans. You’ll meet some of our early pre-human ancestors and find out how paleontologists use fossils to link our ancestors to us. 


In this BrainPop movie, Tim and Moby teach you all about what makes an insect an insect. You’ll learn where insects fall on the tree of life and how they evolved to get there. You’ll get a detailed description of what body parts make up insects like bees, flies, crickets, ants, and beetles.


What do cats, elephants, dolphins, and humans all have in common? They’re all mammals! But what makes a mammal a mammal? In this BrainPOP movie, Tim and Moby will help you better understand these diverse creatures.

Digital Microscope

Use pupil-led learning paths to explore materials, rocks and soils, lifecycles, habitats and microorganisms with videos and photos taken through a microscope.

Eating, moving & growing

Learn about the functions of the body, including the digestive and circulatory systems. Explore the relationship between nutrition and exercise and learn how to look after your body while maintaining a positive body image and enjoying food with all your senses!


Videos, fact files and activities explore the theory of evolution, adaption, selective breeding, how humans evolved from primates and the importance of fossils.


Discover a wide variety of habitats, including woodland, ponds, mountains and estuaries. The module also looks at how plants and animals adapt to their environments, with a focus on food chains.

Life Cycles

Understand the life cycles and reproduction processes of birds, amphibians, insects and mammals. The videos, activities and factfile help children to identify the similarities and differences in each.

Animal Rescue

Understand that animals are suited to their own habitat. Identify how animals and plants are adapted to suit their environment in different ways and that adaptation may lead to evolution

Classifying Animals

Correctly classify animals into their taxonomic groups including: molluscs, crustaceans and arachnids. Describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences, including micro-organisms, plants and animals.

Creature Features

Consider how animals and plants adapt and are suited to their habitat. Identify how animals and plants are adapted to suit their environment in different ways and that adaptation may lead to evolution


Some characteristics of living things are caused by environmental factors and some are passed on from parent to child through genetic inheritance. Recognise that living things produce offspring of the same kind, but normally offspring vary and are not identical to their parents.

Search for Life

Introduction to cells. Understand that living things are made of one or more cells. Identifying scientific evidence that has been used to support or refute ideas or arguments
