Understanding Living Things
In Year Four, students deepen their understanding of biology by exploring how living things are classified, how they process food for energy, and their interdependence within ecosystems.
Classification of Animals and Plants
Students learn to group animals and plants into taxonomic categories using classification keys. Categorisation is based on observable characteristics and behavioural traits.
Invertebrates and vertebrates are sorted into groups that may include amphibians, mammals, and reptiles on land, fish in sea, and birds in the air.
- Vertebrates: Includes animals with backbones (e.g., fish, amphibians, reptiles, birds, mammals)
- Invertebrates: Groups without backbones (e.g., insects, arachnids, molluscs)
Teeth and Digestion
Humans and animals have different types of teeth to aid in the digestion process. Students explore the form and function of incisors, canines, premolars, and molars, linking them to dietary habits.
They also study the digestive system stages, from ingestion to absorption and egestion.
Table: Teeth Functions in Humans
|Type of Tooth
|Cutting and slicing food
|Crushing and grinding food
|Crushing and grinding food
Food Chains and Environmental Impact
Students investigate food chains in different habitats, identifying roles like producers, prey, and predators. They examine how energy flows from one organism to another and the impact of habitat changes on these relationships.
In addition, they explore how changes to land, sea, or air environments affect living things.
- Producers: Typically plants and algae that produce energy through photosynthesis
- Prey: Animals that are consumed by others
- Predators: Animals that hunt and eat other animals
They also discuss the broader environmental impact of different species and the significance of maintaining balanced ecosystems.

Exploring Matter and Materials
In Year Four, students engage with the core components of physical science by examining the properties of matter and understanding the transitions between its states.
Pupils explore the characteristics of solids, liquids, and gases, and investigate the processes of evaporation, condensation, and freezing within the water cycle.
States of Matter
Year Four science curriculum introduces pupils to the three states of matter: solids, liquids, and gases. Students learn to categorise materials based on their properties:
- Solids: Defined by their fixed shape and volume.
- Liquids: Characterised by a fixed volume but no fixed shape, taking the shape of their container.
- Gases: Without a fixed shape or volume, expanding to fill their container.
These concepts are visualised and reinforced through various activities, including sorting exercises and demonstrations.
Changing States and the Water Cycle
The transformation of matter from one state to another is a key concept in Year Four. Students discover how:
- Evaporation: Liquids turn into gases when heated.
- Condensation: Gases cool and change back into liquids.
- Freezing: Liquids turn into solids when their temperature is lowered.
The water cycle is used as a practical example to illustrate these changes, showing how water evaporates from Earth’s surface, forms clouds through condensation, and falls as precipitation, often freezing at higher altitudes or in colder climates.
Educational resources such as STEM Learning provide lesson plans and activities to support these topics.

Energy and Forces
In Year Four, pupils are introduced to the fundamental concepts of energy and forces, including the basics of electricity and the principles of sound.
Through practical experiments and interactive learning, they explore how energy is harnessed and utilised, as well as the different forces that govern motion and stability.
Basics of Electricity
Electricity is a form of energy that flows through circuits which are composed of various components such as cells, wires, bulbs, switches, and buzzers.
Pupils learn that circuits must be complete for electricity to flow, understanding the role that each component plays. They are taught to identify conductors and insulators, recognising materials that allow or prevent the flow of electrical current.
- Components of a simple circuit:
- Cells: Provide the electrical energy
- Wires: Conduct electricity around the circuit
- Bulbs: Convert electrical energy into light
- Switches: Control the flow of electricity
- Buzzers: Convert electrical energy into sound
Sound is a type of energy that is produced when objects vibrate. Year Four science curricula cover how sound travels through different mediums, and how its pitch and volume can change.
The pitch of a sound, how high or low it is, is determined by the frequency of the vibrations: faster vibrations create a higher pitch. On the other hand, volume, or how loud a sound is, depends on the amplitude of the sound waves.
- Properties of sound:
- Pitch: Determined by the frequency of vibrations
- Volume: Influenced by the amplitude of sound waves
Through interactive activities, pupils explore how to change pitch and volume, often using musical instruments or everyday items to demonstrate these concepts.
Conducting Scientific Investigations
In Year Four, pupils are encouraged to engage in scientific investigations that foster a deeper understanding of scientific concepts and develop their ability to work scientifically.
These investigations involve carrying out experiments, making observations, and interpreting data.
Developing Scientific Skills
Year Four students begin to hone their scientific skills by carrying out a range of experiments. They learn to make accurate observations and to take precise measurements, which are essential aspects of collecting reliable data.
For instance, students may measure the temperature of water at different states of matter, using thermometers to record changes. Teachers provide various resources, such as worksheets and access to the library, to support the development of these skills.
Through structured activities, children are introduced to the importance of a fair test.
This concept ensures that when they are carrying out scientific enquiries, they are keeping one variable constant while changing another, allowing them to draw meaningful conclusions from their results.
Working Scientifically With Experiments and Data
The process of working scientifically embraces both the undertaking of experiments and the handling and interpretation of data. Year Four students are guided by their teachers to pose questions, predict outcomes, and then test their predictions through experimentation.
After conducting these experiments, pupils are taught to analyse the collected data, looking for patterns or inconsistencies.
Through the analysis of their findings, they learn how to form conclusions that link back to the original scientific concepts being studied.
These activities not only enhance their understanding of scientific theories but also prepare them to approach future scientific enquiries with a systematic and critical mindset.
Integrating Science With Other Key Subjects
Integrating science education in Year Four with other key subjects ensures a well-rounded learning experience that reinforces knowledge across disciplines.
The National Curriculum in England emphasises the importance of such integration, particularly with maths and English.
Connection to Maths and English
In Year Four, pupils encounter scientific concepts that are closely tied to maths. As they explore various science topics, students engage in the collection and analysis of data, enhancing their numeracy skills.
Measurement and estimation are central to experimental activities, which reinforces their mathematical understanding.
Incorporating English within the science curriculum is equally essential. Pupils develop their reading comprehension by engaging with scientific texts, increasing their vocabulary and understanding of style and plot within informational texts.
They also learn to articulate scientific concepts orally and in writing, boosting their confidence and ability to structure arguments effectively.
Science and Geography’s Inter-relationship
The inter-relationship between science and geography in lower key stage 2 is pivotal for fostering an appreciation of environmental sciences.
When learning about habitats in the science curriculum, pupils also look at different geographical settings, understanding how physical landscapes affect living organisms.
This grounding prepares students for later assessment, as they learn to draw links between various biomes and the species that inhabit them, thereby appreciating the balance of ecosystems.
