micro-organisms‚ along with many other things circulate in the air within our environment. These micro-organisms then settle and become more prevalent in different areas. An experiment was conducted to see where these micro-organisms were present and how widespread and abundant they were. Method: In the experiment‚ there were 3 environments in which agar plates were used to get bacteria and fungi. Environment No.1 was inside the lab with the laboratory air‚ environment No.2 was outside the lab in the

The affect of temperature on the rate of movement of woodlice Aim: The aim of this experiment is to establish whether a change in temperature affects the rate in which woodlouse move. I measured the rate by timing the woodlouse to move a set distance of 20cm‚ and altered the surrounding temperature by submerging a clear tube in water with different temperatures controlled by a water bath. Research: It is to be believed there over 3000 different species of woodlice‚ a total of 42 species

Introduction In the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them) because they
