Every year‚ millions of young children develop back problems due to the ghastly weight of their backpacks. B: Millions of trees are cut down just to make workbooks‚ paper and textbooks.

After observation and research‚ we find out that wood is more suitable for making a beam and more possible to rupture at 20 kg weight. With several trials‚ we discovered that the shape‚ length‚ width and thickness of the wooden board and the distance between two stands are all very important in contributing the result. Any changes of these features may influence the result and make

Bicycle Stopping Distance Design Experiment Introduction Training wheels are additional wheels that are mounted parallel to the rear wheel of a bicycle that have been use to assist children to balance their bicycle until they have developed a usable sense of balance on the bicycle. In this experiment we aim to discover how does the size‚ or diameter‚ of the training wheel affect the stopping distance of the bike thus finding out which size training wheel is the most effective in reducing

recipes are actually based on using sifted flour‚ even if they don’t say to sift the flour. This is because at home we tend to use volume measures like cups and teaspoons‚ but other countries and pretty much the entire foodservice industry relies on weight (Bennion & Scheule‚ 2010‚ p. 78). It turns out that weighing is much safer in terms of getting the right amount. As Bennion and Scheule (2010‚ p. 83) state‚ “one pound of flour will weigh one pound‚ regardless of whether it is sifted.” But‚ if

In Vecchio’s there are no lines of this sort‚ and we distinguish each surface not for the
