1. What Does Science And Technology Have In Common? By Ranard Richburg
2. ELEMENTS As the demand for aluminum grows each year with more and more uses being found for it, recycling becomes ever more important. Aluminum is used to make drink cans since it is a light weight metal that does not rust and resist wear from weather or chemicals.
3. Hydrogen Hydrogen is one of the most reactive gases. It burst easily and often explosively into flames. Hydrogen’s combination with oxygen in water makes it one of the most important elements on the Earth.

5. hALOGENS Halogen lights floodlight a stadium at night, allowing large audiences to watch. Halogens are non-metals and make up part of the seventh main Group in the Periodic Table. … FASCINATING FACT… Fluorides (fluorine compounds) are often added to drinking water to prevent tooth decay.
6. Chemical Reaction Candle Wax contains a mixture of carbon and hydrogen. When lit, the melted wax is drawn up the wick and burns, using oxygen in the air.
8. Glass Certain oxides are added to glass to color it. … FASCINATING FACT… The person who controls the fires and loads the glass into the furnace is called a teaser.
9. New Materials Snowboards are made from composites such as Kevlar, which combines lightness with strength … FASCINATING FACT… New “smart” materials might change their properties in response to conditions
10. Radiation An X-ray image made by passing electronic radiation through someone’s chest. It shows this person has been fitted with a pacemaker.
11. Nuclear Power Like coal and oil power stations, nuclear power stations use steam to drive turbines to generate electricity.
12. Spectrum When the beam from a flashlight passes through a prism it fans out into a rainbow of colors.
