The digestive system is made up of key parts, each of which has a different function.

Enzymes are biological catalysts which speed up reactions including digestion.

Food is a store of energy, transferred from the food to the consumer.

A balanced diet contains the correct amount of all food groups.

There are two types of malnutrition: when and how do they occur?

'Obese' is a medical term used to describe a person with a high excess of body fat.

Lipids include fats (solid at room temperature) and oils (liquid at room temperature).

Vitamins and minerals help the body to use other nutrients efficiently.

Proteins are a vital part of a healthy diet. Protein-rich foods include fish, meat, eggs and beans.

Dietary fibre is plant material that cannot be digested by the human body.

Carbohydrates are an important source of energy in a healthy diet. Starchy and sugary foods are high in carbohydrates.

Starch is a type of carbohydrate. Its molecules contain carbon, hydrogen and oxygen atoms.

Poo (faeces) is the waste that remains after food has been digested and its nutrients absorbed by the body.

Try this experiment and recreate processes in the digestive system with online and lab options.

Learn how digestion works and how to model digestion using a pair of tights.

The human body takes in oxygen and lets out carbon dioxide. Many parts of the body are involved, including the lungs, airways and blood.

Respiration is a chemical reaction which occurs in all living cells, releasing energy from glucose.

Breathing is also called 'ventilation' and is the movement of gases into and out from the lungs.

Anaerobic respiration occurs without oxygen and releases less energy but more quickly than aerobic respiration.

Lactic acid is the waste product produced during anaerobic respiration.

The circulatory system is the heart and all the blood vessels in the body which carry cells and substances to all its parts.

The gas exchange system is the parts of the body involved in breathing, such as the lungs, airways and diaphragm. Different conditions and activities affect this system.

Cells get the energy they need from glucose during respiration. Watch a visual explanation of glucose.

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.

Photosynthesis and respiration are processes that allow plants to make food and release energy.

Temperature, light intensity and carbon dioxide are just some of the factors that affect photosynthesis. These factors can be manipulated to maximise growth.

Try this experiment and use pondweed to see how light intensity affects the rate of photosynthesis.

The maximum amount of air you can breathe in and out is your vital lung capacity. This experiment shows how this can be measured.

Legal and illegal drugs can change how people act and cause health problems.

Learn about communicable diseases and non-communicable diseases - in other words, those that can be spread and those that can't.

Learn how vaccines and antibiotics work in different ways to protect against illness.

Learn about the causes and effects of common mental health issues such as stress, anxiety and depression.

Discussing whether we should ban sugary drinks for under 18s. Can you think like a scientist?

Learn about the cells and body parts involved in reproduction, how a baby grows in the uterus, and what happens at birth.

Learn about sperm and egg cells, and find out how a baby grows in the uterus.

The effects of the menstrual cycle can be different for each person, but here are some of the ways it can change the body.

Flowers reproduce through a process called pollination. Different flowers spread their pollen grains in different ways including using pollinators.

Fruit and seeds help plants to reproduce. Plants spread their seeds through wind, water, animals and explosions.

All organisms in an ecosystem depend on each other. Food chains show the flow of energy from one organism to another.

All organisms in a food web depend upon each other and changes to one can affect the others.

Sampling is the process of looking at part of a population or habitat to draw conclusions about the whole thing. Learn how sampling is used to find out about animals and plants.

Pyramids of numbers and biomass are different ways of showing the amount of organisms at each stage in the food chain.

Learn how different species group together and how they are related to each other.

Plants live in a wide variety of habitats. Learn how each species is adapted to suit where they live.

Biodiversity is a measure of the range of living organisms within a habitat. A gene pool is the range of DNA in a species.

DNA is the genetic code which makes up genes, which are responsible for giving an organism a specific characteristic.

Some variation is passed on via genes and some variation is the result of differences in the surroundings, or what an individual does.

Collecting data on the differences between members of a species can give two different types of results: continuous and discontinuous.

Characteristics like eye colour and genetic diseases are inherited.

Evolution explains how better adapted organisms have an advantage.

Natural selection is known as ‘the survival of the fittest’. The best adapted organisms are able to survive.

Evolution is the process by which small changes in organisms occur over long periods of time and new species are formed.

Selective breeding is when organisms are deliberately bred so their offspring have the desirable characteristics.

Genetic conditions are passed from parents to their children. Learn about conditions that are inherited, such as sickle cell disorder and cystic fibrosis.

Compare the work of two great scientists, Darwin and Doudna.

Discussing whether extinct species should ever be brought back to like. Can you think like a scientist?

Learn how greenhouse gases warm Earth up, and how human activity is putting dangerous amounts of these gases in the atmosphere, causing climate change.

Learn how pollution can cause toxins to enter the food chain and build up to dangerous levels.

How can you work safely in the lab? What are the various steps needed in order to do so? How to spot risks, hazards and understand hazard symbols.

Find out why variables are important in an experiment, including control variables, independent and dependent variables.

A hypothesis is an idea about how something works that can be tested using experiments. A prediction says what will happen if the hypothesis is correct.

Developing a method is an important part of planning an investigation and it is important to evaluate the validity of each step leading up to the conclusion.

Scientific equations and formulae are used to work things out in science. Using standard units means scientists around the world can work together better.

Use diagrams to show how scientific apparatus is set up and how to draw them in 2D. Common practical techniques that use apparatus include filtration, evaporation and distillation.

Calculating averages from data is usually more accurate than using one result. Using a table ensures that data is recorded in an organised way.

Types of data include continuous, discrete and categoric. Data can be presented in a number of ways, which depends on the type of variable and the uses.

Different types of graphs and charts are used to show results. They need to be drawn and labelled correctly. Scientists use patterns in the data to reach a conclusion.

A conclusion sums up what has been found out during an investigation. It should be clearly structured and explained using scientific knowledge.

Scientific studies can be biased; it's important to recognise when this is the case. Scientists review each other's conclusions from new research.
