Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases‚ so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational

The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the

given crop? In our experiment‚ we examine the effects of water on corn. Corn is a vital crop to North America‚ and there is a wide draw to maximizing crop yields. To determine the effects of different amounts of water‚ we tested plants with various watering times according to a schedule. All of the plants experienced all of the same conditions‚ except for the quantities of water

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in

ABSTRACT The study us experimenters re-conducted was based on Norman Triplett’s study of social facilitation and how social presence or encouragement improves an individual’s speed and consistency in their performance. The experiment was replicated in using several trials for accurate results and was split into two stages: a mental challenge and a physical challenge. The two male and two female participants ranged from ages 15 to 17 years old. For the mental challenge‚ each participant was pulled

Success of Dugesia tigrina regeneration in different water temperatures Abstract: The experiment at hand aimed to determine if the species Duguesia tigrina has an optimal temperature for regeneration. The experiment used three different spring water treatments of different temperatures. The treatments included a cool 12° treatment‚ a room temperature 25° treatment‚ and a warm 30° treatment. Each of the D. tigrina were cut in half‚ and each half was placed into a designated section of a water treatment

There are several research design methods that have been developed for the field of psychology. Instead of arguing over which is the best method‚ it is more appropriate to compare two of the favored designs. Each one has positive attributes along with negative factors that may influence results. It is more important to understand and decipher which is the most appropriate method to utilize based upon the theory you are working towards. The two designs that
