Science Beyond Classroom: Barcodes
http://sciencebeyondclassroom.blogspot.com/2009/07/barcodes.html
Friday, July 31, 2009. We see barcodes everyday and almost every where. Before the invention of barcodes, cashiers at stores have to run their deft little fingers across the cash machines to register payment. Now, they just have to beep all items under their scanners. What convenience that little piece of black and white stripes sticker provides! Recall what you've learnt under the topic Light - how does an object appear white / red / black?

http://michellephoo.blogspot.com/2009/08/whos-following-your-footsteps.html
Perspire to Inspire before I Expire. Sunday, August 2, 2009. Who's following your footsteps? Watch what you do. you never know who is watching. I resonate strongly with this video. Once, a teacher said she had a student who came to school one day with a small, black tattoo on her arm. So the teacher called the girl's dad to come to school to highlight this concern to him.

Perspire to Inspire before I Expire: August 2009
http://michellephoo.blogspot.com/2009_08_01_archive.html
Perspire to Inspire before I Expire. Wednesday, August 5, 2009. See beyond the defiant and wild facade, most teens are just confused and scared. The show started with them hauling abuses at their mother but look at the 180 degree change when they saw their mothers' "death". No matter how big size they have grown, no matter how defiant / angry they look, teens are still children in adults' bodies. They would still think of running into their parents' arms when they were scared. May the force be with you,.

Science Beyond Classroom: The Misunderstood Rainbow
http://sciencebeyondclassroom.blogspot.com/2009/07/rainbows.html
Tuesday, July 28, 2009. A student questioned, "If light travels in a straight line, why is rainbow curved? This student believed that rainbow streams from the sun, like sun ray. Sunlight travels in a straight line, "bounced off" rain drops through total internal reflection and the dispersed light spectrum travels in straight line into our eyes. Till now, scientists have not fully understood all aspects of rainbow. Rainbow, by itself, is an interesting field of study. Subscribe to: Post Comments (Atom).
