Biology Coursework ¡V Does The Light 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

Children’s learning and development can be affected by certain person factors and external factors. Personal factors are to do with the person (it’s personal to them) and includes: Learning difficulties; Sensory Impairments‚ Disabilities‚ Health Status (good health or bad health)‚ diet (good diet or bad diet)‚ stress‚ the environment and any environment genetics (asthma‚ smokers). External factors are outside forces‚ such as: Education; Care Status/Family (in care/”broken home”)‚ Family Environment/Background

In this experiment‚ the class examined how the rate of photosynthesis was affected by different light colors at different distances in shoots of a Cabomba plant. The plants were placed in two different beakers‚ one with recently boiled and cooled distilled water and the other with saturated sodium bicarbonate solution. The three different color photoflood lamps used for this experiment were white‚ red‚ and green at four distances of thirty‚ sixty‚ ninety‚ and one hundred-twenty centimeters away

The hypothesis made prior to the experiment was not correct - the distilled water did result in the most weight gain (g); however‚ the 5% salt concentration did not result in the least weight gain (g). Table 1 clearly highlights that the 3% salt concentration resulted in the least weight gain (g). The distilled water resulted in the most weight gain (g) because the solution is hypotonic – a hypotonic solution results in the water diffusing into the cell because the molecules of the substance are

Factors that Affect Management Course/ XMGT 230 To get a good look at how external and internal factors affect management‚ we are going to look at the United States Army and how it is affected daily by global‚ technical‚ innovative‚ diverse and ethical issues. Today now more than ever the world has shrunk and it takes great leaders to command a company to achieve success in the world. By looking at the Army we can see all five examples of factors that affect leaders and managers

One external factor that could affect a child’s development is poverty and deprivation. This splits into 5 categories; diet‚ housing‚ education‚ play & leisure opportunities and aspirations & expectations. If a child is born into a family of low-income‚ the 5 categories above tend to be negatively affected due to a lack of money and opportunities. A poor diet‚ for example‚ can mean that children are fed an unhealthy diet of processed food‚ meaning they are not as healthy and they are unlikely to

What is potential energy? Stored energy that results from the position or shape of an object is called potential energy. 2B.What factors affect an object’s potential energy? The factors that affect an object’s gravitational potential energy are its height relative to some reference point‚ it’s mass‚ and the strength of the gravitational field it is in. 2C. What is the potential energy of a 50-kg pole vaulter when

that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min and 3.5 mL/min

Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes

INVESTIGATING FACTORS AFECTING THE RATE OF PHOTOSYNTHESIS! Testing Carbon Dioxide Done by: Krish S. AIM: is to plan and carry out an investigation on factors affecting the rate of photosynthesis. We are doing this by investigating the amount of bubbles produced by waterweed to show the rate of photosynthesis and the effects of carbon dioxide (CO2). HYPOTHESIS: I think that the rate of photosynthesis will increase as the rate of CO2 increases this can be seen by the bubbles produced from
