Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

Research question “To what extend is one ecosystem more diverse than other one?” Hypothesis If ecosystem has more number of species and organisms within those species‚ it will have higher biodiversity. Justification of hypothesis According to formula for Simpson`s diversity index‚ D = N (N-1) / Σ n (n-1)‚ where N is total number of organisms‚ while n is sum of individuals within a specie‚ we can see that sum of all individuals and total number of organisms of particular species affect the biodiversity

Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

Title: Observation of Macroscopic Chemical Changes‚ Alice Kimbrell‚ Chemistry 101-DS01:74589‚ 5/31/2013. Purpose: In this lab‚ I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change‚ and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these
