Aim: To construct a field graph to study the local ecosystem at the Minnamurra estuary involving abiotic factors‚ transects and abundance. Method: Measuring abiotic factors 1. Measure the elevation along the transect line in centimetres using an inclinometer in each quadrat. 2. Measure the soil temperature in degrees using a thermometer by placing it in the ground in the quadrat. 3. Measure the air temperature in degrees using a thermometer by holding it up in the air just above the ground

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow

Mariana Mendoza Alvaro Puccini Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases‚ the amount of salt and copper

NT1310 Unit 9 Assignment 1 A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962‚ early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness.When a light-emitting diode is switched on‚ electrons are able to recombine with holes

Homeostasis Lab: The Effects of Exercise on Homeostasis Lab Write Up Introduction: The purpose of this lab is to discover the effect that various levels of exercise have on specific body parameters such as heart rate‚ body temperature‚ perspiration level‚ body color‚ and breathing rate. Homeostasis will be monitored to calculate the change in such body parameters. To find this information the subject will exercise for a controlled periods of time. At each rest‚ the subject will be recorded upon
