Help with primary-school science homework

Help with primary-school science homework. As well as being a compulsory national curriculum subject, learning about science helps children explore, observe and understand more about the things around them. Your child will cover a variety of different science topics in EYFS science , KS1 science and KS2 science which will develop their investigative skills and their knowledge of life and living things, materials and physical processes. A new national curriculum for science was introduced in September At some stage, you'll need to support your child with their science homework, perhaps helping them research a topic, create a poster or presentation, carry out experiments at home and record results or even visit science museums.

Whatever science topic your child is learning about, Homework Gnome is a great place to start! To get started, just look through the list below to find the science topic your child is studying at school now.

Find out more here. Find out why minibeasts are so important and which one has been around for million years! To use all this electricity, we have to make it — this is called generation. Electricity is very important in the modern home, and it has completely changed the way that people live their lives — can you imagine living without any electrical things in your home, like most Victorians did?

We have to be careful how we use it, though. It takes a lot of work to generate electricity, and some of the ways we do have bad side effects on the environment.

Because Britain is north of the equator, the sun is always to the south of us in the sky. This means that in Britain it is best to put solar panels facing south, so that the sun shines on them for as much of the day as possible. Electricity can also be a lot cleaner and nicer than the alternative.

In , the London Underground started to use electric trains because it meant there was no dirty, smelly smoke from steam engines in the tunnels and stations.

All underground railways around the world soon did the same thing. Lots of electricity is generated by burning fuels that create greenhouse gases and contribute to global climate change. People are trying to reduce this by generating more energy by environmentally-friendly methods like wind or solar power. Nuclear power stations often look similar to coal or gas power stations with lots of big cooling towers.

Electricity can be very dangerous when it travels through you. It can seriously hurt or even kill people. Not all items that use electricity have to be plugged into mains sockets. Batteries can be used to store small amounts of electricity so that it can be used in small things that you can carry around like iPods and video game players.

Coal — coal is turned into electricity by burning it to make steam to turn a turbine; unfortunately, this makes carbon dioxide that causes global warming Cooling towers — these are used at power stations to get as much heat as possible out of steam that has been used to make electricity; this makes the power stations more efficient.

They are normally very wide towers, and sometimes look as though they have clouds coming out of them! It saves money, and helps the environment. Help find out how to power different electrical items , and how to be safe with electricity suitable for KS1. Try to create enough power from a solar panel and a wind turbine before the clock stops!
