Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the

Outlines “Voice of the Streets: The Birth of a Hip-Hop Movement” Author: Jackson Allers Title: Voice of the Streets: The Birth of a Hip-Hop Movement Topic The topic is hip-hop and social issues. Thesis The author claims that Arab hip-hop was not an insular clique any more and its music can have impact on the larger society as the responses from this Arab hip-hop movement. Main points When Jackson interviews the MCs‚ he finds bribes might happen during the events Ground Zero: Jackson looks

He charges towards the white horizon. He sprints‚ unknownst to what awaits him at the end. Being next to the sand makes him feel empty and although he does not completely know why he’s running‚ he does know he doesn’t want to be near it. The sand makes him feel as if he’s lost something that he cannot recover and rather than face it‚ he runs. He races for a while‚ never looking back‚ trying to depart from the unwanted feelings. Without warning‚ he hears in a far away voice behind him.“Stay in the

We can see through the results that there isn’t a normal proportional relationship between the wavelength of the light and the rate of photosynthesis and instead it starts relatively high then decreases and increases again. The colour red gives the highest rate of photosynthesis (89 bubbles per minute) with blue giving the second highest rate of photosynthesis (70 bubbles per minute)‚ and yellow giving the third highest rate of photosynthesis (64 bubbles per minute) and green with by far the least

How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in

fundamentally different microscopes now in use today: the light microscope and the electron microscope- both of which utilize different forms of radiation in order to create an image of the specimen being examined. The light microscope‚ so called because it employs visible light to detect small objects‚ is probably the most well-known and most commonly used research tool in the laboratory. Here‚ Specimens are illuminated with light which then passes through two sets of lenses known as

In conclusion‚ one can determine how photosynthesis is impacted by light intensity through the experimentation on ivy leaf disks in a bicarbonate solution. The function of the sodium bicarbonate in this experiment was to provide a sufficient amount of carbon dioxide (CO2) for the photosynthesis process to occur. Without CO2 or any of the other necessary reactants‚ glucose nor oxygen cannot be produced. The leaves rise and sink due to photosynthesis occurring in the plant cells. As the carbon from

article “Let There Be Light” tries to explain that we need our natural darkness by using evidence‚ reasoning‚ and persuasive elements. Evidence is the available body of facts or information indicating whether a belief or proposition is true or valid. In paragraph 3 it states‚ “ world health organization classifies working the night shift as a probable human carcinogen…. “. An human carcinogen is something that causes cancer. This statement is saying that artificial light at night can be a cause

White light and refraction: White light from the Sun is made up of all the various colours of visible light. Each of these colours has a different wavelength - red light (at one edge of the rainbow) has a wavelength of ~650 nm‚ whilst violet light (at the other edge) has a wavelength of ~400 nm. When light travels from one medium (say air) to another (water)‚ it changes speed‚ and if the light enters at an angle‚ it will bend. This is known as refraction. Shorter wavelength light (such as violet)
