Hey guys!<\/p>\n

Hope you all enjoyed your holidays and got to do some cool things. I can\u2019t believe that they flew by so fast. Almost as fast as that fancy fast car<\/a> I was telling you all about last week.<\/p>\n

Much as I am sad that holidays have ended, I\u2019m always pleased to go back to school.<\/p>\n

I found out that it is National Science Week in the first week of August (1-7th<\/sup>). This is an initiative of the Department of Science and Technology <\/a>and there will be all sorts of exciting activities going on around the country during this week.<\/p>\n

Obviously at places like Sci-Bono Discovery Centre<\/a> they have whole programs organised. Maybe you should ask your teacher to check out what is going on \u2013 or you can go to their website and see for yourself.<\/p>\n

There will also be lots of events and expos at shopping malls and other interesting places. Keep an eye out.<\/p>\n

This year the theme is International Year of Light<\/a> and light-based technologies.\u00a0 I know we spoke a bit about light several blogs ago.\u00a0 We always tend to think that dear old Eskom is responsible for the light \u2013 the ones you turn on and off \u2013 but there is just so much more to light than the electricity stuff.<\/p>\n

Have you ever thought about natural light \u2013 for example light in nature?<\/p>\n

Just think about one of the most frequent visual displays of light in nature\u2026 sunsets! Sunsets are a result of refraction. In astronomy, sunset is the point when the trailing edge of the Sun\u2019s sphere disappears below the horizon. The brilliant array of colours that appear in the sky during sunset are created by scattered airborne particles passing through rays of white sunlight travelling through the atmosphere. Because the evening air contains more particles than morning air (okay \u2013 this is pollution we are talking about), sunsets are typically more radiantly coloured than sunrises.<\/p>\n

Then there are rainbows\u2026 a rainbow is a beautiful natural phenomenon that occurs when drops of rainwater meet sunlight. The multi-coloured arch is produced by a major process called refraction, or the \u201cbending\u201d of light.<\/p>\n

And let\u2019s face it \u2013 all our food grows because of light. Without it \u2013 the cupboards would be bare.<\/p>\n

If you can think of other sources of light\u2026 let me know.<\/p>\n

Cool word for the week: Array<\/p>\n

Meaning: selection, collection, display, range<\/p>\n

Example: My Dad has a wonderful array of books \u2013 I think he has just a book on about every topic one could think of.<\/p>\n","protected":false},"excerpt":{"rendered":"
