of that drink is contaminated with dye? In this experiment‚ with the use of a spectrophotometer‚ the amount of concentrated dye in three drinks will be tested. First‚ the dye itself will be examined to see what the optimal wavelength and absorbance will be when created in a serial solution. Red Dye 40 was the prime object that will be studied in this lab because it is one of the most common dyes in every day drinks. Before performing any experiment though‚ it is important to understand

using “previous knowledge‚ evidence and observations to formulate tentative theories about why things happen the way they do.” So‚ using our prior knowledge we hypothesised that bigger parachutes would create more air resistance. This appears to be supported by Devereux (2007‚ p55) who states: “The air offers a greater resisting force to objects that have a large surface area…” Our prediction of what would happen therefore was that as the parachutes got bigger‚ due to increasing air resistance their

1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons
