1. Physical Science · Forces change the motion of an object.

  1. Pushes & Pulls: Understand that pushes and pulls are forces that can change the speed or direction of an object's motion, and compare the effects of different strengths and directions
  2. Balanced & Unbalanced Forces: Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object
  3. Forces Vocabulary: Name and describe forces using precise vocabulary — force, push, pull, twist, stretch, squash, contact force, non-contact force, gravity, weight, friction, air resistance, upthrust — and distinguish between forces that require physical contact and forces that act at a distance
  4. Contact & Non-Contact Forces: Notice that some forces need contact between two objects (contact forces) while magnetic forces can act at a distance (non-contact forces)
  5. Gravity & Falling Objects: Explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object

2. Life Science · Some kinds of organisms become extinct when their basic needs are no longer met or the environment changes.

  1. What Living Things Need: Understand what plants and animals (including humans) need to survive: water, food, air, and suitable conditions
  2. Changing Environments: Recognise that environments can change and that this can sometimes pose dangers and challenges to living things
  3. Dinosaurs Were Real: Understand that dinosaurs were real animals that lived on Earth a very long time ago and are now extinct — none are alive today
  4. How fossils form: Describe in simple terms how fossils are formed when things that have lived are trapped within rock over millions of years
  5. Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago
  6. How Fossils Form: Explain in simple terms how fossils form: an organism dies and is quickly buried in sediment; over millions of years minerals replace the remains and the sediment turns to rock, preserving the shape

3. Life Science · Living things cause changes on Earth.

  1. Living, Dead & Never Alive: Explore and compare the differences between things that are living, dead, and things that have never been alive
  2. Fast & Slow Earth Changes: Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock)

4. Earth and Space Science · Long and short term weather changes occur due to changes in energy.

  1. Why seasons change: Make observations at different times of year to relate the amount of daylight to the time of year, noticing longer days in summer and shorter days in winter
  2. Geography & Local Weather: Know that different places around the world have very different typical weather — tropical places are hot and wet all year, deserts are very dry, polar regions are freezing cold — and that geography (distance from the equator, altitude, nearness to the sea) affects local weather
  3. Weather vs climate: Obtain and combine information to describe climates in different regions of the world, distinguishing between weather and climate

5. Earth and Space Science · Water is present in the atmosphere.

  1. Where water is found on Earth: Identify where water is found on Earth and understand that water can exist as solid (ice) or liquid, recognising water in oceans, rivers, glaciers, and underground
  2. Types of Weather: Identify and describe different types of weather — sunny, rainy, windy, snowy, cloudy, foggy, stormy — and describe what the weather is like today using simple vocabulary
  3. What Is Wind?: Know that wind is moving air, that it can be gentle (a breeze) or very strong (a gale), and that wind can move things like leaves, kites, flags, and even push people
  4. Evaporation & the Water Cycle: Identify the role of evaporation and condensation in the water cycle, and associate the rate of evaporation with temperature

6. Earth and Space Science · The atmosphere is primarily made up of air.

  1. What Causes Wind: Understand what causes wind: the Sun heats the Earth's surface unevenly, warm air rises because it is lighter, and cooler air rushes in to take its place — this movement of air is wind
  2. The Atmosphere: Know that Earth is surrounded by a layer of air called the atmosphere, that air has weight and exerts pressure, that the atmosphere protects us from harmful radiation and keeps the planet warm enough for life, and that weather happens in the lowest layer (troposphere)
