The Effect of Water on Germination and Plant Growth in Marigolds Question: How does the amount of water given to a plant affect how much it grows? Hypothesis: If I give water to a marigold seed then it will germinate and the plant will grow more than a seed not given water. Independent Variable (IV): the amount of water given a seed/plant Dependent Variable (DV): the amount of plant growth Control Group: The group of plants given water Experimental Group: The group of plants given no water

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

halogen light bulbs in lighting fixtures for filming? – The benefits of using the halogen lights could be that they can last longer and are much brighter than regular light bulbs. 2. Describe in detail how to create the effect of light coming through a window onstage in a theatrical production. – A metal cutout will create an effect of a light shining through a window‚ so that it doesn’t look like a straight up spotlight on stage. 3. What is hard light? How does it differ from soft light? How can

Photosynthesis Lab Report Introduction The lights are essential for photosynthesis and it plays a major role. All the food we eat and all the fossil fuel we use is a product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms but usually by plants and algae. All these organisms convert CO2 (carbon dioxide)

Interactions of light and matter Young was able to explain this result as a wave-interference phenomenon – the double-slit interference pattern demonstrates the wave-like nature of light. Free download and print from www.itute.com ©Copyright 2009 itute.com Explaining the interference pattern using the wave model Light has been described both as a particle and as a wave. Isaac Newton (~1665) made up a particle model of light to explain many of the known behaviours of light at that time

neon lights: -consists of brightly glowing electrified glass tubes or bulbs that contain rarefied neon or other gases History: -Neon (the element) was discovered in 1898 by William Ramsay and Morris W. Travers. After they had discovered neon‚ they had explored neon’s many properties using an electrical gas discharge tubes. They later wrote that “the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget.” -following neon’s discovery‚ neon tubes

Light Effects Refraction‚ reflection and dispersion are all processes which happen when a ray of light is shone at either a glass block‚ a mirror or a prism. The ray box is the light source. Mirror When the ray box is shone at a mirror the angle of incidence is always a few degrees different to the angle of reflection. For example‚ if you shine a light ray into a mirror at 60* then it will reflect out at about 57*. Glass Block If I shine a light ray into a glass block then the light would

“Light Up Nippon” I was watching on the television on how the tsunami eaten up the Japan on March 2011; devastating numerous cities and killing thousands of people whether young or old‚ poor or rich. After the incident‚ you could see the buildings‚ houses‚ establishments and infrastructures that were once standing tall‚ firm and beautifully constructed were now on the floor scattered into pieces‚ destroyed and wrecked. It doesn’t take a person to realize how the resident of Japan felt after the

lesson‚ you need to know a little bit about light. White light consists of all the colors of the rainbow mixed together. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Isaac Newton thought that light must be a particle because particles of light that travels in straight lines until they are
