Investigation Problem: How does light affect the rate of Photosynthesis? The Plan In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1. The apparatus I am going to use are the following: - 1 Tripod 1 300ml Beaker 1 Boiling Tube 1 Clamp Stand 1Clamp 1 Boss 1 Ring Binder 1 Lamp 1 1 Metre Ruler 1 Thermometer 1 Stop Clock To do the experiment I will set up the apparatus first. I will firstly

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Photosynthesis summary Photosynthesis [photosynthesis: The chemical change

Factors that Determine the Currency Exchange Rates Exchange rate is often referred to as the nominal exchange rate. It is defined as the rate at which one currency can be converted‚ or ’exchanged ’‚ into another currency. For example‚ the pound is currently worth about 1.824 US dollars. One pound can be converted into 1.824 dollars. This is the exchange rate between the pound and the dollar. There are four types of currencies can be operated‚ which are a floating‚ managed and fixed exchange

THE EFFECTS OF CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis

The aim of this experiment was to replicate the Primacy effect‚ which investigates the effects of ascending and descending performances on attributions of intellectual ability‚ illustrating that individuals’ perception of another individual is influenced by their first impression of that person to the detriment of all subsequent impressions. The design included independent groups‚ and the 46 participants over 16 years old (25 males and 21 females) were chosen through convenience sampling. The latter

Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. Variables The input variable which will be used in this investigation will be the light intensity (this will be a 100Watt bulb being moved closer and further away from the plant). The outcome variable which will change

Abstract Acid Rain has a lot of effects on living organisms and on the environment. This experiment has two purposes. One is to determine the acidity of rainwater in certain areas in the Philippines. Another purpose is to determine which type of area-urban or rural- is more subjected to acid rain. The experiment was done by first collecting rainwater from selected rural and urban areas. After the collection was done‚ the rainwater samples were tested using a pH meter. The results of the pH test

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best
