field notes, student observers recorded: the activity, the number of people involved in the activity, the gender of the participants, the ages of the participants, the ethnicities of the participants, the location of the activity, the time of day of the activity, any activity comments (further detailing the setup of the activity), and also any observation comments (detailing what happened with the activity under observation). The number of participants in the group was noted from 1-10, and anything
measures, calculate the FOG reading ages. Hypothesis 1: Word Length Task First, I am going to work out which article tends to use longer words. Plan and Hypothesis I am going to record the number of letters in each of the first 100 words in both articles. I will not count numbers written as figures as words and I will ignore abbreviations like "e.g." and "etc." However, I will count words with a hyphen between them as separate words. I predict that the word lengths will be longer

The Effect of Concentration on the Rate of a Reaction Aim- Our aim is to investigate the effect of concentration in the rate of a reaction. Method- Below is a step-by-step guide to exactly what we did to do the experiment. The first thing we did or we do in any experiment involving acid is put on safety goggles so we do not ruin our eyes. Ø We then went and gathered up the equipment to complete the experiment. The list is below: Ø A Balance (scales) Ø A gas syringe (100 cm
Introduction for division: In mathematics, especially in elementary arithmetic, division (÷) is the arithmetic operation that is the inverse of multiplication. Specifically, if c times b equals a, written: c x b = a, where b is not zero, then a divided by b equals c, written: a/b =c Online: In general, "online" indicates a state of connectivity, while "offline" indicates a disconnected state. In common usage, "online" often refers to the Internet or the World Wide Web.

Product of Any Given Number When Split into Parts The objective of this coursework is to find the formula that gives the maximum product of any given number when split into parts. For the first part of the coursework I am going to investigate the splitting of a number into two parts, then three parts and into four and five parts. For each number of parts, I am going to come up with a formula that gives the maximum product. Starting number 12 PAIR WHICH TOTAL
The Relationship Between Height and Weight for the Pupils in a Secondary School Introduction ============ For this investigation, I am going to use data on secondary school pupils to find the distribution of the data and also to look for any meaningful relationships between the heights and weights of the students. When I was looking at the various things that I could study, one of the factors that I looked at was data collection. The amount of data was large, spanning across
giving a slow reaction. As you increase the temperature, the particles should collide with more energy giving a faster reaction. The concentration of the acid, the time given inbetween each measurement, the surface area of marble chips, the number of marble chips, the volume of acid and the catalyst all affect the rate of reaction. The higher the concentration of acid, the more chance the particles have of colliding. The longer the time between each measurement, the longer time the
The Effect of a Catalase on the Breakdown of Hydrogen Peroxide Aim To follow the progress of a catalysed reaction by measuring the volume of gas produced as the reaction proceeds. Using the initial rates of a series of experiments I will be able to find the orders of the reaction with respect to enzyme and substrate. Also to find out if concentration has an effect on the reaction when an enzyme is used to accelerate the breakdown of hydrogen peroxide. Introduction / Background Information
had an equal chance to be picked, by doing this it made my sample non-bias. I ended up deciding to use the random number generator method, which involved the use of a calculator. I gave each student in the school a specific number, so I could easily locate them. The numbers would vary depending on year group and gender. · I would go to my calculator and generate a random number by pressing ‘SHIFT’ and ‘RAN#’ from 0 to 1(e.g. 0.167) · Then I would multiply the figure by the total amount
Effect of Burning Fossil Fuels on Limestone Buildings Introduction Some buildings around cities are made from Limestone. For example the Minster in York. Over the years some features of the building have been warn away, this is due to acid rain. Acid rain has many other effects on life around us. It Also: * Acidifies Lakes and ponds * Metal ions being washed out of soil * Damage to the gill of fish * Nutrients drained of leaves and soils * Roots damage to tree leading to
population to have happened. This process can be simplified in equation, easy steps and symbols as follows: n1 = number of animals first marked and released. n2 = number of animals captured in the second sample m2 = number of marked animals in the second sample N = Total Population m2/n2 = n1/N N = n1 x n2 / m2 -If the number of animals recaptured in the second sample (n2) is less than 8, the estimation of the population is likely to be biased. -If there are losses
The Amount of Joints and Rods in Various Different Structures I intend to draw the structures I am investigating on isometric grid paper and record the results in tables. I will then state formulae to calculate the amount of rods or joints in any size structure. To back up my formulae I will be making predictions and proving them to be correct (hopefully!) Joints ====== Inside the structures I will be investigating the joints I predict to find are the following: -----------
The Effect of Temperature on the Action of Peroxidase Enzyme Aim To find the effect of temperature on an enzyme in this case peroxidase, by studying it decomposing hydrogen peroxide. Planning I am measuring the amount of gas given off in the reaction. By collecting this figure I can determine the rate of reaction. If I know the rate of reaction I can find out what temperature peroxidase works best at. Equipment · Trough · Clamp · 100ml measuring cylinder · Stop clock
Factors that Affect the Bounce of a Ball Introduction There are many factors which will affect the bounce of a ball: · The size and shape of the ball · The material the ball is made from · The surface it is bounced on · The weight of the ball For example, a ball dropped on sand would absorb more energy than a ball dropped on a concrete floor. Aim To investigate the bounce of a ball. Prediction I predict that when you decrease the height you release the ball from
Math Investigation of Painted Cubes Introduction ============ I was given a brief to investigate the number of faces on a cube, which measured 20 small cubes by 20 small cubes by 20 small cubes (20 x 20 x 20) To do this, I had to imagine that there was a very large cube, which had had its outer surface painted red. When it was dry, the large cube was cut up into the smaller cubes, all 8000 of them. From there, I had to answer the question, 'How many of the small cubes will have
Investigation of the Most Favorable Sport Practiced by Youth Introduction The shooting Club in Mohandessin is a very famous sporting club in Cairo. Almost all the sports are practiced in that club as it the biggest.. Most of People living in Mohandessin district are members of that club and most of them practice one or more sport. The sports are played more frequently during the weekend which is Friday and Saturday as during the week they are busy either with studying or work. I realized
