Students will observe and explain the processes of melting and freezing, relating them to temperature changes.

Students will investigate evaporation and condensation, understanding their roles in the water cycle and everyday phenomena.

Students will learn about less common changes of state, sublimation (solid to gas) and deposition (gas to solid).

Students will identify natural and artificial light sources and understand how our eyes detect light.

Students will demonstrate and explain that light travels in straight lines, forming the basis for shadows and vision.

Students will investigate how light reflects off different surfaces, particularly mirrors, and its applications.

Students will explore how shadows are formed when light is blocked by opaque objects, and factors affecting their size and shape.

Students will classify materials based on their ability to transmit light and explain how this affects visibility and shadow formation.

Students will explore how different colours of light combine and how objects appear in different coloured lights.

Students will differentiate between heat as a form of energy and temperature as a measure of hotness or coldness.

Students will learn to use thermometers accurately and understand different temperature scales.

Students will investigate heat transfer through conduction in different materials, identifying good and poor conductors.

Students will explore heat transfer through convection in liquids and gases, understanding the formation of convection currents.

Students will learn about heat transfer through radiation, which does not require a medium, and its properties.

Students will describe the arrangement and movement of particles in solids, liquids, and gases and relate it to their properties.

Students will investigate the processes of melting and boiling, understanding them as changes of state involving heat energy.

Students will identify the major human body systems and understand their general functions.

Students will identify and describe the main organs involved in the human digestive system.

Students will trace the journey of food through the digestive system and understand the breakdown of nutrients.

Students will learn how digested nutrients are absorbed into the bloodstream and transported to body cells.

Students will identify the major bones and functions of the skeletal system, including support and protection.

Students will explore different types of muscles and how they work with the skeletal system to produce movement.

Students will identify the organs of the respiratory system and understand the process of gas exchange.

Students will learn about the heart, blood vessels, and blood, and their role in transporting substances throughout the body.

Students will identify what magnets are, their basic properties, and common magnetic materials.

Students will be introduced to microorganisms, focusing on bacteria and fungi, their characteristics, and roles.

Students will explore the unique physical and chemical properties of water that make it essential for life.

Students will trace the continuous movement of water on, above, and below the surface of the Earth.

Students will investigate sources of water pollution and explore methods for water conservation and purification.

Students will define force, identify different types of forces, and understand how forces cause changes in motion.

Students will investigate friction as a force that opposes motion and its effects.

Students will explore gravity as a universal force of attraction and its effects on objects on Earth.

Students will learn to accurately measure distance and time, which are fundamental to describing motion.

Students will define energy and identify its presence in various forms around us.

Students will identify and describe different forms of energy, including light, heat, sound, electrical, chemical, and mechanical.

Students will investigate how energy can be transformed from one form to another, following the law of conservation of energy.
