Life and living processes

Your child will learn about cells and cell functions and how these relate to life processes in a variety of organisms.

They will investigate humans as organism, looking at digestion, the role of enzymes and how products are absorbed into the bloodstream. They will also explore the rest of the human body - the skeleton, joints and antagonistic muscle pairs (for example, biceps and triceps), reproduction and adolescence, the respiratory system, and the effect of alcohol, solvents, and other drug abuse on health.

Finally, they will be taught about green plants and their environment. They will study photosynthesis, classification and breeding and ways to protect living things and the environment.

Materials

Children will learn how solids, gases and liquids can be characterised by melting and boiling point and density, how chemical reactions form compounds and how solubility changes with temperature. They will learn to recognise chemical changes in everyday situations (ripening fruit, cooking food etc).

They will also explore metals and how they react with oxygen, water, acids and oxides of other metals, and what the products of these reactions are.

Physical processes

Children will learn about series and parallel circuits, how to measure current and voltage, magnetic fields, and that ‘like' magnetic poles repel and ‘unlike' poles attract.

Forces and motion is another key topic. Children will learn how to determine speed and that the weight of an object on Earth is the result of the gravitational attraction between its mass and that of the Earth. They will also learn about the positions of the Earth, sun and moon and about the use of artificial satellites and probes to observe space.

In exploring light and sound, children will learn about how light and sound travels, that white light can be dispersed to give a range of colours, that sound causes the eardrum to vibrate and that people have different audible ranges.

Finally, children will learn about energy resources and conservation - the distinction between renewable and non-renewable resources and how temperature can lead to transfer of energy.

Help your child at home

  • Discuss the selective breeding of fruit and vegetables to suit the consumer market (specific size of carrot, seedless grapes etc).
  • Note when environmental topics are featured in the news. Use this as an opportunity to consider some of the issues in the light of what your child is learning at school.
  • Get cooking! Use any opportunity to point out the chemical reactions that might be occurring, such as using lemon juice to prevent avocado turning brown, using baking powder to make cake. There's plenty of information on these processes in the Planet Science Diner at www.planet-science.com.
  • Check out www.sciencebob.com to learn how to build an electromagnet.
  • Introduce your child to the website www.solarsystem.org.uk. First explore the Solar System, and then challenge your child to try their hand at the ‘World Builder' in which they have to design a new planet - launch it, and see whether it can support life, or whether it crashes and burns.
  • Invest in Encyclopedia of Science (Dorling Kindersley, £14.99). It’s the perfect companion for homework or projects.

(Fun KS3 Science revision quizzes to teach students in Year 7, Year 8, and Year 9)

Science is how the world goes around. Or rather, it’s the study of how the world goes around. Whether it’s the littlest bug (let’s call him Jerry, that sounds like a little bug’s name) or the biggest solar system, through observation and experiment, Science aims to explain the unexplainable.

In KS3, you’ll notice the stuff you tackle is a little bit trickier.

You’re older now. Wiser, too. That means it’s less of the simple stuff and more into the intricate - and amazing! - avenues of Science. Take Jerry for example (the little bug from earlier, remember?), well he’s made up of atoms. And the plant that Jerry sits on? That plant has organs. There’s so much to discover in Science, and we’re going to take you through the key topics on the National Curriculum.

Curious to know what KS3 Science will cover? There are plenty of topics to get you through Year 7, Year 8 and Year 9. Here’s an idea of what you’ll be looking at...

From studying acids and alkalis to plants, forces and metals, you’ll always have a fresh challenge. We teach Science Buffs like you all about food chains, electricity, pressure, reactions and more! Learning Science is a non-stop, whizz-tacular ride and we can’t wait to show you what exciting stuff we’ve got to share.

Our quizzes make sure Science is never dull. We know you like to learn quickly and we keep up with fast-paced quizzes that will test you in all areas. The best part? Our quizzes can be completed anywhere! Whether you’re lounging on your sofa, sitting at the dining table or at your desk, our quizzes are on hand to introduce you to all corners of Science.

Science gives you the opportunity to learn more about our brilliant planet and everything on it. Scientists never stop asking questions and we’re excited to show you what they’ve uncovered so far.

Magnifying glasses at the ready. We’re about to discover great things.
