0 of 19 concepts ready to learn · Markdown, for your AI

1. Earth’s Systems · Understand the structures of the Earth’s surface using models.

1. Shapes of land and water: Develop a model to represent the shapes and kinds of land (mountains, valleys, plains) and bodies of water (rivers, lakes, oceans) in an area
2. Finding patterns in data: Analyse and interpret data from maps to describe patterns of Earth's features, recognising that many features result from processes that occur over long periods

2. Earth’s Place in the Universe · Remember the major components and patterns observed in the earth/moon/sun system.

1. Sun, Moon, and stars: Use observations of the sun, moon, and stars to describe predictable patterns such as the sun rising and setting, the moon changing shape, and stars appearing at night
2. Shadows: Represent data in graphical displays to reveal patterns of daily changes in shadow length and direction, day and night cycles, and seasonal star patterns
3. The solar system: Describe the sun, Earth, and moon as approximately spherical bodies, and describe the movement of the Earth and other planets orbiting the sun in the solar system
4. Our Solar System: Know that there are other planets besides Earth and that our group of planets orbiting the Sun is called the solar system — and that space is the vast area beyond Earth's sky
5. The Sun is a star: Know that the Sun is a star — the closest star to Earth — and that it is at the centre of our solar system, with all eight planets orbiting around it

3. Ecosystems - Interactions, Energy, and Dynamics · Understand how environmental factors aid in the survival of plants.

1. How animals adapt to environments: Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time

4. From Molecules to Organisms- Structures and Processes · Understand how plant structures aid in survival.

1. Structures for Survival: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction

5. From Molecules to Organisms- Structures and Processes · Understand human body systems and how they are essential for life: protection, movement, and support.

1. The Immune System: Know that the body has an immune system that protects against illness: the skin acts as a barrier, white blood cells identify and destroy germs (bacteria and viruses), and vaccines train the immune system to recognise specific diseases before they cause illness
2. Skeletons & Muscles: Identify that humans and some other animals have skeletons and muscles for support, protection, and movement

6. Energy · Understand how energy can be transferred from one object to another.

1. How energy travels around: Observe and provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents

7. Motion and Stability- Forces and Interactions · Understand motion and factors that affect motion.

1. 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. Friction & Surfaces: Compare how things move on different surfaces, noticing that some surfaces create more friction than others
3. 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

8. Matter and its Interactions · Understand the structure and properties of matter before and after they undergo a change.

1. Heating & Cooling Changes: Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
2. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties
3. Solids, Liquids & Gases: Compare and group materials as solids, liquids, or gases based on their observable properties and behaviour
4. What happens when things collide: Ask questions and predict outcomes about the changes in energy that occur when objects collide
