Methods of production Production methods fall into three main categories; however‚ all production methods can be assisted with CAM and CAD equipment (Computer Aided Manufacture and Computer Aided Design – respectively). 1. Job Production and Prototype Production Job Production is used when a product is produced with the labor of one or few workers and is scarcely used for bulk and large scale production. It is mainly used for one-off products or prototypes‚ as it is inefficient; however‚ quality

Aim: This is the reason for doing the experiment. It may contain a research question‚ but it must state what it is that we are investigating or what we hope to find out. Hypothesis: This is the basis behind your plan which leads you to believe that the experiment can be successfully carried out. It may also contain a prediction of the final answer (supported by a reason) Method: This is what was actually done or is going to be done. It may need a diagram‚ in which case it should be drawn

Census Method All items in any field of inquiry constitute a ‘ Universe ’ or ‘ Population.’ A complete enumeration of all items in the population is known as a census inquiry. It can be presumed that in such an enquiry‚ when all items are covered‚ no element of chance is left and highest accuracy is obtained. But in practice this may not be true. Even the slightest element of bias in such an inquiry will get larger and larger as the number of observation increases

Abstract: This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do
