Renewable or non-renewable? How to energise our world? There are many different ways to harness energy for human use. Though in the end, nearly all types of energy can be traced back to the sun and other stars.
We are a strong online mall, the main business clothing,
shoes, bags and other kinds of products.
Leading brands have Nike, fan saizhe, Jordan, LV etc.
Due to business needs, want to in all over the world to find distributors,
wholesalers, retailers. As our partner, can enjoy member offer.

This lesson considers energy sources and resources, both renewable and non-renewable.
There are many different ways to harness energy for human use. Though in the end, nearly all types of energy can be traced back to the sun and other stars
Lately, everyone has been stressing over oil shortages and rising gas prices. And why shouldn't they? At four dollars per gallon, everyone’s pocket-book has seen better days.
Well, there are other ways to make gasoline, like making it from coal. It’s called coal gasification. The technology’s been around for decades, but it’s always been expensive. Now, researchers have streamlined the process so that it’s more efficient, cheaper, and creates less pollution.
In this demonstration, students can get an overview of different types of radiation and can label them as alpha, beta and gamma. They can also see that there are different ways of detecting the different types of radiation.

Resource UPDATED August 2016. Thank you for all the positive comments and ratings.
This highly visual presentation contains 67 slides that will get your learners thinking about electricity and electric circuits. Scaffolded note-taking worksheets for pupils, homework assignments and a quiz are also provided. Appropriate for your Year 7 or Year 8 pupils. Learning objectives covered in this resources are listed below.
• By the end of this lesson, pupils should know:
1. that electricity is a form of energy.
2. that current electricity can be produced from cells, batteries or the mains
3. that there are a range of appliances in the home, which use electricity.
4. that we can represent components by symbols.
5. that current electricity flows in conductors but not in insulators.
6. that a complete path is needed from one side of the battery to the other for electricity to flow.
7. how a switch works.
8. that there are two types of circuit, series and parallel.
9. that current is measured in Amps.
10. that current is measured using an ammeter.
11. how to connect and use an ammeter.
12. that in a series circuit, the current is the same all the way round the circuit.
13. that in a parallel circuit, the current is shared but not lost or used up.
14. that the current in a series circuit depends upon the number and type of components used.
15. that a battery is a store of electrical energy.
16. that voltage is a measure of the amount of energy or push given to the current.
17. that more cells in series equals more voltage.
18. that the effect of voltage upon current and bulb brightness.
19. that an electric current causes a wire to become hot. .
20. that the bigger the current, the higher the temperature of the wire.
21. that if too much current flows, the wire will melt.
