Science: KS3


Students follow the Collins KS3 course throughout years 7 and 8 which is carefully matched to the new National Curriculum for science. Each year, students will complete 2 topics in each of the 3 main science areas. Each topic is assessed in line with school policy with a half termly assessment.  

Year 7 

Autumn Term

Mixing, Dissolving and Separating – this is the first introduction to science at high school and students will become more familiar with using laboratory equipment safely and effectively. 

Students will also look at solubility and will study distillation and chromatography as useful ways of separating mixtures. 

Forces and their Effects – Students will consider different types of force and things that forces do.  They will look at friction in more detail (the useful and unwanted) and will be introduced to levers and turning forces. 

Spring Term

Cells – students will explore different types of cell, looking at how cells are the building blocks of life; considering how our understanding of living things have changed through history and incorporating ideas about reproduction – both in plants and animals. 

Elements, Compounds and Reactions – in this topic students will consider how ideas about elements, and atoms have changed over history. 

Students will begin to understand the periodic table, they will consider the usefulness of simple models to help us understand how elements join and react together to make new materials. 

Summer Term

Eating, Drinking and Breathing – in this second biology topic, students will find out about healthy diets and will study how our food is digested by our bodies. 

Students also study our breathing systems and will look at how lifestyle choices and disease can affect breathing. 

Energy Transfers and Sound - in this second physics topic, students will look at energy stores and energy transfers. 

They will study fuels as special chemicals that release energy when burnt and will look at how energy is carried by sound. 


Year 8 

Autumn Term 1 (to October half-term)

Plants and Ecosystems – students will find out about the environment and will look at the relationships between organisms in the environment. 

They will look at the role of plants as producers and will find out about plant adaptations, plant transport systems and the minerals plants need to keep them healthy. 


Particles– students will revisit the particle model and use it to explain different states of matter. 

They will also consider how the particle model can be used to explain density, concentration and diffusion.  Students will build on a basic understanding of particles by learning about atomic theory. 


Autumn Term 2 - Spring Term 1 (October half term to February half term)


Exploring Contact and Non-Contact Forces – students will look at gravity and space travel; electrostatic and magnetic forces; and pressure, floating and sinking. 


Getting the Energy Your Body Needs – students will explore the roles of the skeleton, action of muscles as well as looking at aerobic and anaerobic respiration. 


Spring Term 2 to Summer Term 1 (February half term to May half term)


Explaining Chemical Changes – In this topic students will find out about acids, alkalis and indicators.  They will study acid and alkali reactions and also look at combustion in detail. 


Magnetism and Electricity – students will look at how magnets work in more detail.  They will find out about electromagnets and will look at series and parallel circuits. 


Summer Term 2 (May half-term to July)


Variation for Survival - students will learn about variation and classification.  They will explore the structure of chromosomes, genes and DNA, and will look at their importance in the inheritance of characteristics.
