Paper Electron diffraction through a graphite film. Mark Raskin Skidmore College (11/14/14) Abstract: In this paper‚ the wave-like properties of electrons are discussed. We are trying to measure the inter-atomic spacing (d) between the graphite atoms‚ which we are accelerating electrons through. As the electrons pass through the graphite‚ an interference pattern emerges on the screen in front of the gun. The interference pattern shows up as a circle within a circle‚ each of which represents

Types of variables There are many types of variables like the dependent‚ independent‚ moderating‚ intervening‚ discrete‚ continuous‚ extraneous etc.‚ Dependent variable As the name suggests the value of a dependent variable is influenced by other variables. It is the main variable of interest to the researcher. Understanding the variables that influence

AS91601 Final Report Carry out a practical investigation in a biology context‚ with guidance. Name : Olivia Nilson Introduction Slaters (woodlice or porcellio scaber) are often found in gardens. They usually like to hide in cool moist dirt or in cold places such as under pots or bricks Aim : To investigate how temperature affects the speed of slaters Hypothesis : I predict that the slaters will move faster when the temperature is increased‚ above their preferred temperature range‚ as they try

The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will

Task 2a: A system of transport is found within most multi-cellular organisms enabling the growth of these organisms to be greater than those single-cellular organisms. The transport system enables the rapid delivery of nutrients and oxygen as well as the removal of waste products such as carbon dioxide from all the cells within the body in order for them to survive. All cells within the body require the intake of substances from the environment and the removal of any unwanted substances. Within a
