and the rate of photosynthesis in spinach leafs. The rate of photosynthesis was measured every five min under light colors of white‚ green‚ red‚ blue and yellow under a light intensity of 2000 lux. The rate of photosynthesis was measured by the spinach disk method in which we replaced the air from the disks with sodium bicarbonate using a vacuum. Under photosynthesis‚ oxygen‚ a product of photosynthesis‚ replaced the bicarbonate solution‚ made the disks less dense and rise to the top. The rate of photosynthesis

into nitrogen‚ which then helps the plants because the plants need nitrogen in order to live. The aquaponic system consists of two main parts the reservoir and the grow bed. The reservoir holds fish and the grow bed holds the plants. It works by using a pump that takes the water up to the grow bed from the reservoir and waters the plants as well as giving them nutrients from the fish such as ammonia. The fish benefit from the plants because the ammonia product could

Investigating the Effect of Light Wavelength on the Rate of Photosynthesis Method Take a 250cm3 beaker and fill it with distilled water. Use distilled water so there are no impurities to disrupt photosynthesis. Then take x cm’s of elodia and put it in the beaker. Cover the elodia with the large end of a funnel and the tip of the funnel cover with a test tube. Then direct a light onto this experiment. Measure the amount of bubbles that come from the elodia for x minutes. A prediction

Investigation 5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them

Abstract: The rate of photosynthesis and cellular respiration can change in varying conditions. How does the rate change with varying degrees of temperature and light exposure? To test this algae beads were exposed to a CO2 indicator‚ which changes colors based on the level CO2 level present. The algae beads were exposed to two different variables‚ light and temperature and tested for color change‚ Ph‚ level‚ and CO2 absorbance level. The beads were exposed to a light and a dark condition‚ and another

Measuring poverty Poverty is the condition of lacking basic human needs such as food‚ clean water‚ health care‚ clothing‚ and shelter due to the inability to afford them. This is also referred to as absolute poverty or destitution. Relative poverty is the condition of having fewer resources or less income than others within a society or country‚ or compared to worldwide averages. When measured‚ poverty may be absolute or relative poverty. Absolute poverty refers to a set standard which is consistent

work at the current wage rate but cannot find work despite seeking for a job. Claimant count is a measure of unemployment which includes those unemployed people who are eligible to claim the Job Seeker’s Allowance or who have enough National Insurance Credits. It is very reliable because the data is collected by the government; it shows exactly how much percentage of people actually claimed for the JSA. On the other hand‚ the measure can be very inaccurate for measuring the percentage of people

Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide‚ affected the rate of photosynthesis. The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). A valid conclusion was made and most of the results were in accordance with the prediction‚ although there were some anomalies present. The errors and limitations were evaluated and some improvements were suggested. Introduction: Photosynthesis

Measuring the Viscosity of Motor Oil ME331 Laboratory Assignment #1 Prepared for: Prof. Sangeorzan Submitted by: Abstract An experiment was conducted to model the effect of temperature on the viscosity of motor oil and compare the results to commercial values established by the Society of Automotive Engineers (SAE) for SAE 30‚ SAE 40 and SAE 5W30. The viscosity of the oil sample at eight temperatures between 20 °C and 55 °C was determined using a rotary Brookfield DV-II+ viscometer

between light intensity and photosynthesis that could normally be seen had the experiment taken place without errors. The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis would take place in the algal balls. This would result in more CO2 being present because it wouldn’t be being used up during photosynthesis. The decrease in CO2 in the
