Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy. Materials: Light Emitting Diodes

chemicals that control reactions in living cells. They are biochemical catalysts‚ speeding up reactions that would occur too slowly to be of any usefulness to an organism. Although in organisms‚ it is not necessary for the reactions to be at maximum rate at all times. Enzymes interact with other molecules to produce a stable system in which the products are made when they are needed in the exact amount. An enzyme lowers the activation energy of a reaction so its easier to proceed. Enzymes are specific

Light pollution Light pollution‚ also known as photo pollution or luminous pollution‚ is excessive artificial light. This phenomenon is pronounced around urban centers‚ where city lights diminish the view of stars and planets. In addition to brightened skies around cities‚ light pollution also refers to any outdoor light that creates glare and interferes with the natural night environment. Cause Light pollution results from outdoor lights aimed

Bugs Attraction to Colored Lights Introduction: This experiment was conducted to see which colored light pill bugs would prefer more out of red‚ blue‚ yellow‚ and green lights. If pill bugs went to the green and yellow lights more than the blue and red lights‚ then this means they like brighter lights more than gloomier lights. For the experimental group‚ the colors used were blue‚ red‚ yellow‚ and green. The controlled group was the middle chamber. It got regular light from the classroom. The independent

Ninan 9/27/2006 Mr. Astmann English 103 The Great Affects of Football From the early ages in history to present day‚ sports have had a major impact on society. Football is a very popular sport played in America and many other countries. Some may say that football is a violent sport and its not beneficial in any way‚ but in reality it gives a person all the basic tools needed not only for playing the game‚ but also how you interact with people in society. Also it is very simple to get

Diaz‚ Zenki P. September 15‚ 2014 Professor Cathlyne Alvarez Philo 1 THV 1 Void I am going to start this reflective paper with the most predictable beginning: What does it mean to love for the sake of love? Getting to the main point commenced with research first‚ tackling concepts about love‚ particularly on what it is. What is love? The Merriam Webster Dictionary defines love in various ways‚ some of which are the following – Love is a strong affection for another arising out of

Introduction In this experiment I aim to find out if caffeine has an effect on the heart rate of daphnia. Daphnia are water fleas that have a sort of heart that we can see in magnification. We can count the number of heart beats in a minute of a regular daphnia and try and get a new one with the same specifications as the old one that may have died. It is also a good idea to get a new one as we want to see how much it affects it from ordinary instead of adding the caffeine one after another

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks

In the paper‚ "Adoptive Identity: How Contexts Within and Beyond the Family Shape Developmental Pathways" by Harold D. Grotevant‚ Nora Dunbar‚ Julie K. Kohler‚ and Amy M. Lash Esau‚ the paper focuses on adoptive identity‚ how identity is influenced by social changes‚ and what the different contexts of development are. (Grotevant et al. 379) I will support the author’s claim which
