Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

By “electric current”‚ I mean by the rate at which electric charges moves through a circuit‚ the electric charges can either be ions or electrons. They are measured in ammeters and the unit that is measured in is ampere which is the number of charges that passes through per second. There are many factors which would affect the electric current‚ like the voltage of

Aim. The aim of this investigation is to find out how Slaters react to an increase or decrease of the temperature in its surroundings. Hypothesis The speed of the Slaters will increase when the temperature of its environment is increased or decreased from its preferred range‚ so it ensures that they spend less time in unfavorable conditions to avoid desiccation. Method 1. This experiment is done using a water bath to change and control the temperature being trialed. The water bath will have

The search of the crime scene is to look for any clues and for evidence that may like to the crime. These object or material may be anything that may serve as tool by witch I can use to give a good idea of what may happen during the crime. The next element is to Collecting and preserving evidence found at the scene. Evidence that links to any crime must be carefully collected‚ since evidence
