'For with God Nothing Shall Be Impossible' (Luke 1:37) BELIEVING, LEARNING AND SHARING TOGETHER: The June ONLINE SAFETY newsletter is now ready to view in the Newsletter section. Year 6 will be swimming every afternoon for the next two weeks. Please make sure your child has their full swimming kit with them each day. If you are interested in a place in EYFS for September 2024, please call the school office on 01254 812581 as we only have two places left. Please can I remind parents that holiday leave in term time is not authorised. The approved holiday list for 2024-25 is now available to view in the parent - term dates section of the website.

Learning Together

Science in KS2

Lower Key Stage 2 Pupils:


Pupils should have the opportunity to broaden their scientific view of the world around them. They should do this through exploring, talking about, testing and developing ideas about everyday phenomena and the relationships between living things and familiar environments, and by beginning to develop their ideas about functions, relationships and interactions.


They should ask their own questions about what they observe and make some decisions about which types of scientific enquiry are likely to be the best ways of answering them, including observing changes over time, noticing patterns, grouping and classifying things, carrying out simple comparative and fair tests and finding things out using secondary sources of information. They should draw simple conclusions and use some scientific language, first, to talk about and, later, to write about what they have found out.

Pupils in years 3 and 4 should be given a range of scientific experiences to enable them to raise their own questions about the world around them. They should start to make their own decisions about the most appropriate type of scientific enquiry they might use to answer questions.


Pupils should read and spell scientific vocabulary correctly and with confidence, using their growing word-reading and spelling knowledge.



Upper Key Stage 2 Pupils will be taught:


Pupils should develop a deeper understanding of a wide range of scientific ideas. They should do this through exploring and talking about their ideas; asking their own questions about scientific phenomena; and analysing functions, relationships and interactions more systematically.


At upper key stage 2, they should encounter more abstract ideas and begin to recognise how these ideas help them to understand and predict how the world operates. They should also begin to recognise that scientific ideas change and develop over time. They should select the most appropriate ways to answer science questions using different types of scientific enquiry, including observing changes over different periods of time, noticing patterns, grouping and classifying things, carrying out comparative and fair tests and finding things out using a wide range of secondary sources of information.


Pupils should draw conclusions based on their data and observations, use evidence to justify their ideas, and use their scientific knowledge and understanding to explain their findings.


They should use relevant scientific language and illustrations to discuss, communicate and justify their scientific ideas and should talk about how scientific ideas have developed over time.


Pupils should read, spell and pronounce scientific vocabulary correctly.

National Curriculum Working Scientifically

Expected standard at the End of Key Stage 2

Year 3, 4, 5

 & 6

  • Use appropriate scientific language from the national curriculum
  • Describe and evaluate their own and others’ scientific ideas related to topics in the national curriculum (including ideas that have changed over time), using evidence from a range of sources
  • Ask their own questions about the scientific phenomena that they are studying, and select the most appropriate ways to answer these questions, recognising and controlling variables where necessary (i.e. observing changes over different periods of time, noticing patterns, grouping and classifying things, carrying out comparative and fair tests, and finding things out using a wide range of secondary sources)
  • Use a range of scientific equipment to take accurate and precise measurements or readings, with repeat readings where appropriate
  • Record data and results using scientific diagrams and labels, classification keys, tables, scatter graphs, bar and line graphs
  • Draw conclusions, explain and evaluate their methods and findings, communicating these in a variety of ways
  • raise further questions that could be investigated, based on their data and observations.

National Curriculum

Expected standard at the end of Key Stage 2

Year 3, 4, 5

 & 6

  • Name and describe the functions of the main parts of the digestive (Y4), musculoskeletal (Y3) and circulatory systems (Y6); and describe and compare different reproductive processes and life cycles in animals (Y5)
  • Describe the effects of diet, exercise, drugs and lifestyle on how the body functions (Y6)
  • Name, locate and describe the functions of the main parts of plants, including those involved in reproduction (Y5) and transporting water and nutrients (Y3)
  • Use the observable features of plants, animals and micro-organisms to group, classify and identify them into broad groups, using keys or other methods (Y6)
  • Construct and interpret food chains (Y4)
  • Describe the requirements of plants for life and growth (Y3); and explain how environmental changes may have an impact on living things (Y4)
  • Use the basic ideas of inheritance, variation and adaptation to describe how living things have changed over time and evolved (Y6); and describe how fossils are formed (Y3) and provide evidence for evolution (Y6)
  • Group and identify materials (Y5), including rocks (Y3), in different ways according to their properties, based on first-hand observation; and justify the use of different everyday materials for different uses, based on their properties (Y5)
  • Describe the characteristics of different states of matter and group materials on this basis; and describe how materials change state at different temperatures, using this to explain everyday phenomena, including the water cycle (Y4)
  • Identify and describe what happens when dissolving occurs in everyday situations; and describe how to separate mixtures and solutions into their components (Y5)
  • Identify, with reasons, whether changes in materials are reversible or not (Y5)
  • Use the idea that light from light sources, or reflected light, travels in straight lines and enters our eyes to explain how we see objects (Y6), and the formation (Y3), shape (Y6) and size of shadows (Y3)
  • Use the idea that sounds are associated with vibrations, and that they require a medium to travel through, to explain how sounds are made and heard (Y4)
  • Describe the relationship between the pitch of a sound and the features of its source; and between the volume of a sound, the strength of the vibrations and the distance from its source (Y4)
  • Describe the effects of simple forces that involve contact (air and water resistance, friction) (Y5), that act at a distance (magnetic forces, including those between like and unlike magnetic poles) (Y3), and gravity (Y5)
  • Identify simple mechanisms, including levers, gears and pulleys, that increase the effect of a force (Y5)
  • Use simple apparatus to construct and control a series circuit, and describe how the circuit may be affected when changes are made to it; and use recognised symbols to represent simple series circuit diagrams (Y6)
  • Describe the shapes and relative movements of the Sun, Moon, Earth and other planets in the solar system; and explain the apparent movement of the sun across the sky in terms of the Earth’s rotation and that this results in day and night (Y5)
