Investigations in Light Intensity Change through Angular Displacement Guiding Question How does the intensity of light change as the angle of incidence to the light source increases? Prediction of Results Predict what you think will happen and what type of equation and graph might best fit the data representing the intensity of a light as the angle of incidence increases. Objective After completing this lesson‚ a student should be able to analyze light intensity striking a surface at varying

What Factors Affect the Rate of Photosynthesis in living leaves? Abstract: In this lab‚ four different types of leaves were tested to see the rate at which each leaf photosynthesized. This lab demonstrates how plants store light‚ capture light‚ and use light as energy for reproduction and growth‚ by photosynthesis. The control in this experiment was spinach‚ which was tested before any of the other plants were. The other plants that were tested were English Ivy‚ C4 Plant‚ and a multicolored

HIIT or high intensity interval training is basically has a succession of intervals of intense and light exercise. Always starts by heating 2-10 minutes. Then followed the dismissal of the interval (from 20 seconds to 2 minutes) intense exercise and light exercise. Number of pairs interval (fast-slow) depends on the fitness exercisers‚ how long it is this kind of training‚ the duration of the interval and the intensity of exercise in "fast" interval. HIIT training is only one of a modification of

Individual Discussion Spectroscopy Dry Lab Lab Section M5 - Group 6 January 24‚ 2015 Discussion In this laboratory assignment‚ the spectroscopy data and molecular formula were given for 3 unknowns. An effort was made to conclusively identify these unknown samples using only the spectroscopy data‚ specifically 1H-NMR‚ 13C-NMR‚ and IR spectroscopy. Although mass spectrometry was given for the samples as well‚ its use was suggested only for confirmation‚ not identification‚ of the unknowns

Purpose: The purpose of the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister

To do the lab exercises for this 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

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that

The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

Heart Rate Vs. Exercise & Gender Introduction The purpose of this experiment was to find out whether males or females of the same fitness levels had a higher increase in heart rate after performing the same exercise in the same amount of time. The hypothesis was that‚ with the same levels of fitness‚ females would have a higher heart rate. The main reason that this hypothesis was thought to be viable‚ was because females generally have higher heart rates than males due to their smaller heart size

Light Lab Introduction: The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light. In order to begin this experiment you must begin by wrapping the “BioChamber” with aluminum foil to prevent light from coming through to the leaves‚ however‚ once the lid has been covered you are to poke holes so you can insert the sensors. Next‚ you will
