and create a scene‚ there is a good chance they will get what they want. These are kids who don’t understand the value of money. At what age should parents start giving their kids an allowance? Studies show‚ if you start at age 5 or 6‚ kids are old enough to understand the difference between want and need. They are also old enough to be taught how to keep their money in a safe place.

Biodegradable Plastic from Gabi Leaves By: Mickaela Olan 9-Apple PLASTIC • A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. ADVANTAGES OF PLASTIC: • Advantages of plastic are light in weight. • They can be easily moulded and have

Abstract: Caffeine‚ (C8 H10 N4 O2) a white‚ crystalline alkaloid known as a nervous system stimulant found commonly in tea leaves and coffee‚ can be extracted using the method of sublimation with the use of Methylene Chloride (CH2Cl2) and Sodium Hydroxide; both can repeatedly rinse the green (unroasted) coffee beans from the caffeine. Keywords: Caffeine‚ Methylene Chloride‚ Sodium Hydroxide‚ Anhydrous Sodium Sulfate I. Introduction Caffeine is an alkaloid of the methylxanthine family. Its chemical

Extraction of Caffeine from Tea Leaves Introduction Caffeine is soluble in boiling water and as a result it is easily extracted from tea bags by steeping in hot water. This process leaves behind the water insoluble portions of the tea bag. However‚ water extracts more than just caffeine‚ so a final separation is done with an organic solvent that will dissolve primarily caffeine. The organic solvent used in this experiment is Dichloromethane (CH₂Cl₂). Dichloromethane is less polar than water
