Thiscontainer could be displaced vertically in order to change the water level. We would thenmake a tuning fork vibrate above the pipe and change the water level until the resonance wasat maximum intensity.Hypothesis: The

4W Experiment to Verify Snell’s Law of Refraction and to Estimate the Speed of Light inside a Transparent Plastic Block 1. Preparation: a) Read about refraction of waves and Snell’s Law. b) Find the relation between the refractive index of a medium and the speed of light in that medium. c) Read about total internal reflection; especially the definition of the “critical angle of incidence”. 2. Using the special apparatus provided‚ measure the angles of refraction corresponding to a wide range of

IB Physics Internal Assesment – Design Aspect 1: Focused problem: Investigate the relationship between the surface area of a circular hole and the time water takes to drain through it. Variables: Independent: Surface area of the hole Dependent: Time water takes to drain Fixed: Amount of Water Container Environmental Conditions Aspect 2: Control of the Variables The independent variable in this case is the surface area of the hole‚ and the dependant will be the time water takes

Lacsap’s Fractions The aim if this IA is to investigate Lacsap’s Fractions and to come up with a general statement for finding the terms. When I noticed that Lacsap was Pascal spelt backwards I decided to look for a connection with Pascal’s triangle. Pascal’s triangle is used to show the numbers of ‘n’ choose ‘r’(nCr). The row number represents the value of ‘and the column number represents the ‘r’ value. Eg. Row 3‚ colomn 2 = 3C2 =

Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the

Determining the equilibrium constant from pH values of changing concentrations of ethanoic acid Design Research question: How will altering the concentrations of ethanoic acid affect the pH value‚ and‚ in-turn‚ the equilibrium constant? Background information: When weak acids react‚ the reaction typically does not go to completion. Rather‚ the system goes to an intermediate state in which the rates of the forward and reverse reactions are equal. Such a system is said to be in chemical equilibrium

Aim To Find the Number of Moles of Water of Crystallisation in Copper (II) Sulphate salt. Introduction Water of crystallisation is the term given to the molecules of water that are used to build up a crystal lattice in some ionic compounds.In copper II sulphate the blue crystals would be impossible without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most
