Red And Blue Coloured Sheets
1,515 wordsInvestigation Into The Factors That Affect The Rate Of Photosynthesis In Elodea Investigation into the factors that affect the rate of photosynthesis in Elodea Introduction Photosynthesis is the chemical process, which takes place in every green plant to produce food in the form of glucose. Plants use the suns energy to join together water and carbon molecules to make the glucose, which is sent around the plant to provide food. Cells in the root or stem can use the glucose to make energy, if the...

Temperature See Attatched Document A Certain Point
3,723 wordsHarry Fox 11 ST Biology Science 1 - Strand 1: Planning Aim In my experiment, my aim is to find out any correlation between rate of respiration of glucose by yeast and the mixtures temperature. I shall do this by conducting an experiment which will involve the timing of the yeast, water and glucose which has been mixed with a little methylene blue. I shall time how long it takes to revert to the original colour using a control. This shall be done at various temperatures. To obtain the best range ...

Metre After The Ramp For The Trolley
2,609 wordsPhysics Investigation: Investigating how the height of a runway affects the average speed of a trolley Planning: Aim The aim of this experiment is to show how the height of a ramp from which a trolley rolls down will affect its run off speed. Preliminary The preliminary experiment we did prior to the investigation enabled me to choose what factors of the investigation I should keep the same or alter. My results from the preliminary displayed that I should perform the following procedures: - The ...

Results Of The Experiment
1,534 wordsPsychology experiments are usually long, painstaking surveys and tests that sometimes take years to complete. They do, however, give us some insight into how the human mind works and develops from the day we are born to the day we die. Deciphering the information these experiments generate is sometimes just as hard as performing them, and to a person with no background in psychology it is almost impossible. The following three experiments were found on the APA website and are good examples of mo...

Salt And The Resulting Flame Colour
690 wordsExperiments to determine the identity of metals by examining the colour of flame when samples of that metal are heated. The aim of this experiment was to find out whether different metals had different reactions when subjected to the flame of the Bunsen burner. This might then allow the classification and identification of certain metals if they have their own reactions, which will be different coloured flames for this experiment. It was hard for me to predict what would occur during the experim...

1,609 wordsA Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila, more commonly known as the fruit fly, is a popular species used in genetic experiments. In fact, Thomas Hunt Morgan began using Drosophila in the early 1900's to study genes and their relation to certain chromosomes (Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila can lay hundreds of eggs after just...

Ph And Surface Area Of The Potato
2,230 wordsIntroduction In this experiment, I will be studying the activity of the enzyme catalase. Catalase breaks down of Hydrogen peroxide H 2 O 2 into water H 2 O and oxygen O 2. catalase 2 H 2 O 2 2 H 2 O + O 2 catalase Hydrogen peroxide water + oxygen Enzymes are biological catalysts. They are made up of protein. They will only act upon one substance, is substrate. Enzymes only work at their optimum in a specific environment. There are many different factors in their environment, which affect an enzy...

Ticker Timer Trolley Experiment Results
1,287 wordsMethod In this experiment I aim to find out how the force and mass affect acceleration. I shall do this by setting up an experiment involving a ticker tape timer and trolley, to keep the experiment as fair as possible I will only change one variable at a time. For the first part I will only vary the force (see fig. 1) in difference weights of 1 N, 2 N, 3 N and 4 N. In order to keep the friction acting on the trolley constant I will make the ramp which the trolley is on at the exact angle so it w...

1,951 wordsThomas LevineAbstractMany cyberneticist's would agree that, had it not been for web browsers, the deployment of link-level acknowledgements might never have occurred. Given the current status of homogeneous models, theorists famously desire the evaluation of online algorithms, which embodies the confirmed principles of separated programming languages. We present a solution for the refinement of Markov models, which we call Drabber. Table of Contents 1) Introduction 2) Drabber Study 3) Implementa...

Light Bulb At Different Temperatures And Currents
1,468 wordsPhysics Project The Planning Key V A Variable resistor Ammeter Light bulb Voltmeter I am carrying out an experiment to find the different resistances created by a light bulb at different temperatures and currents. Because of the nature of a light bulb, it glows white-hot when fully on, the resistance will change at different currents. When the current is low and the bulb is not very bright, it wont be as hot and therefore it will have less resistance. But when the current is high and the bulb is...

Factors The Rate Of Photosynthesis
1,330 wordsPhotosynthesis investigation Spot skill, Analysis and Evaluation Aim To investigate the effect changing the level of light has on the rate of photosynthesis. What is photosynthesis? Photosynthesis is the process through which light energy, water, and carbon dioxide are converted to carbohydrate and oxygen in the presence of chlorophyll. Photosynthesis takes place in the leaves. Photosynthesis needs all the factors to work steadily, if we limit one of these factors the rate of photosynthesis will...

Distance From The Aperture To The Screen
431 wordsOris John-Baptiste Physics Assignment Studying the diffraction from a single slit, using a laser beam. Introduction The aim of the experiment is the study the diffraction from a single slit using a laser beam. Diagram Method The laser beam was projected through a narrow slit onto a screen. The width of the slit was adjusted to view the different pattern changes on the screen. When a pattern of reasonable size was found, the central maximum was measured as shown in the diagram above. The distance...
