Students will investigate the process of cellular respiration, understanding how glucose is broken down to release energy for cell functions.
Students will examine the structure and function of the respiratory system, focusing on the mechanics of breathing and gas exchange in the lungs.
Students will explore the components and function of the circulatory system, including the heart, blood vessels, and blood, in transporting vital substances.
Students will investigate the structure and function of the nervous system, including neurons, the brain, and spinal cord, as the body's communication network.
Students will explore the endocrine system, identifying major glands and the hormones they produce, and understanding their role in regulating body functions.
Students will learn about the body's immune system, distinguishing between different types of pathogens and how the body defends itself against disease.
Students will investigate common medicinal drugs, understanding their intended effects, dosages, and potential side effects.
Students will examine the impact of recreational drugs on the body and brain, focusing on the concept of addiction and its consequences.

02The Periodic Table and Atoms
Unlocking the secrets of the elements and how the arrangement of atoms dictates the properties of matter.
Students will describe the properties of solids, liquids, and gases using the particle model, explaining changes of state.
Students will identify the subatomic particles within an atom, understanding their charges, masses, and locations.
Students will identify the atomic number as the number of protons and the mass number as the sum of protons and neutrons, without detailed calculations for isotopes.
Students will understand that electrons occupy shells around the nucleus and that the number of outer shell electrons determines an element's reactivity.
Students will explore the historical development of the Periodic Table, recognizing the contributions of scientists like Mendeleev and the rationale behind its organization.
Students will identify groups and periods on the Periodic Table and analyze trends in reactivity and properties for alkali metals, halogens, and noble gases.
Students will classify elements as metals, non-metals, or metalloids based on their characteristic physical and chemical properties.
Students will define elements as pure substances composed of only one type of atom and explore common elements and their symbols.
Students will understand that atoms join together in fixed ratios to form compounds, focusing on the idea of chemical bonds rather than detailed mechanisms.
Students will distinguish between mixtures and compounds, exploring different types of mixtures and methods for separating them.
Students will identify the signs of a chemical reaction and understand that atoms are rearranged, not created or destroyed.

03Energy and Motion
Investigating the laws of physics that govern how objects move and how energy is transferred.
Students will calculate speed, distance, and time, and represent motion using distance-time graphs.
Students will identify different types of forces (e.g., gravity, friction, air resistance) and understand their effects on objects.
Students will understand how balanced and unbalanced forces affect an object's motion, leading to constant velocity or acceleration.
Students will be introduced to Newton's First and Second Laws of Motion, understanding inertia and the relationship between force, mass, and acceleration.
Students will understand gravity as a force of attraction and differentiate between mass and weight.
Students will identify different forms of energy (e.g., kinetic, potential, thermal, chemical) and how energy is stored and transferred.
Students will understand the principle of conservation of energy, recognizing that energy cannot be created or destroyed, only transferred or transformed.
Students will understand work done as a transfer of energy when a force moves an object, focusing on qualitative understanding rather than calculations.
Students will understand power qualitatively as the rate at which energy is transferred or work is done, without complex calculations.
Students will identify wasted energy in energy transfers and discuss how to reduce it, focusing on the concept of efficiency qualitatively.

04The Dynamic Earth
Analyzing the geological and atmospheric processes that shape our planet over time.
Students will identify the main layers of the Earth (crust, mantle, outer core, inner core) and their key characteristics.
Students will be introduced to the theory of plate tectonics, understanding how the Earth's crust is divided into plates that move.
Students will investigate the causes and effects of earthquakes and volcanic eruptions, relating them to plate tectonics.
Students will investigate the formation of igneous rocks from molten magma or lava, identifying common examples and their characteristics.

Students will investigate the formation of metamorphic rocks from existing rocks under intense heat and pressure, identifying common examples.
Students will understand the continuous process of the rock cycle, explaining how rocks transform from one type to another.
Students will distinguish between weathering and erosion, exploring the physical, chemical, and biological processes that break down and transport rocks.
Students will identify the layers of the Earth's atmosphere and understand its composition, including the role of different gases.
