One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction

The Human Heart Rate Aim: To study changes in the rate of the human heartbeat. Introduction: Blood is sent pulsing through the body’s veins‚ arteries and capillaries with each beat of the heart. The circulation of blood through the body delivers oxygen and food to the cells and removes wastes. The cells cannot survive if circulation stops for even a small amount of time. With an increase in body movement there is an increase in the cell’s energy use and the heart rate must increase to pump

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the
