Online animation explains that different parts of an electric circuit make up a system. Science lesson also provides limited sample questions at the end of the topic. THE ELECTRIC CIRCUITExplains an electric circuit is a system made up of components and conductors.Explains that some materials allow electric charge to flow through them - these are called electrical conductors. Explains that metals like copper, iron and steel are examples of good electrical conductors. Explains electrical insulators do not allow electricity to pass through them. Plastic, wood, glass and rubber are good electrical insulators. Explains an electric circuit is made when the components and conductors are connected so that electric charge can flow through. Explains an energy source can be a cell, a battery or the mains supply. Explains the components use the electric energy to transform into other forms of energy. Useful for teachers of science/physics. |

Online animation explains that energy allows various things to work (including humans and machines). Science lesson also provides limited sample questions at the end of the topic. WHAT IS ENERGYExplains that energy is the ability to work.Explains all living things and machines need energy in order to work and move. Explains all energy originally comes from the sun. Explains energy from the sun is stored in food, which is used to provide living things with energy to work and move. Explains that wind energy turns windmills. Explains the amount of energy from a windmill depends on how hard the wind blows. Explains Power stations produce electricity using fossil fuels. Useful for teachers of science/physics/chemistry/biology. |

Online animation helps pupils to gain an understanding of the different direct sources of water pollutions. Science lesson also provides limited sample questions at the end of the topic. DIRECT SOURCES OF WATER POLLUTIONExplains that water pollution is a big problem in the world today.Explains water is precious and a basic resource, so we need to prevent its pollution. Explains that direct sources of pollution are the toxic wastes from various industries that are dumped into lakes, rivers and oceans. Explains that toxic waste enters the surface and ground water making the water unsafe. This can make people sick and kill fish. Explains ocean pollution contaminates or kills ocean animals and our food. Explains that some mining methods have devastating environmental and public health effects. Explains sewage or manure entering the water causes organic matter to grow more and more, this leads to low oxygen levels that kill other animals. Useful for teachers of science/geography/earth science/living environment. |
