The spiral bacteria are spirilla (singular form is spirillus) and the rod-shaped bacteria are bacilli (singular form is bacillus). The coccus (plural form is cocci) bacteria are spherical and are usually found in clusters or chains. Bacilli have a large surface area that helps them take in nutrients, but they may dry out easily. Cocci…
Aim To standardize a sodium hydroxide (NaOH) solution against a primary standard acid [Potassium Hydrogen Phthalate (KHP)] using phenolphthalein as indicator. Variables Independent variables Mass of KHP (mKHP) Volume of KHP solution Dependent variables Volume of NaOH added [since the colour change will not happen at exactly the same volume of NaOH added (VNaOH)] Controlled…
Although there has yet be a general concurrence as to what the essence of the relationship between the mind and body is, it is reasonable to assume that the physicochemical properties of the brain drive physical processes of the body. It still remains unclear as to how these neural states achieve meaning and intentionality. The…
Existentialism is defined as the philosophical theory, which holds that a further set of categories, governed by the norm of authenticity, is necessary to grasp human existence. What makes this philosophical argument distinct is not its concern with existence overall, but rather its claim that thinking of human existence requires new categories that are not…
The theory of objectivity states that all beliefs and assertions are either true or false. All beliefs and assertions pertain to the world and its state of being and the world exists in its own reality regardless of any assertion or belief one may have. Because the world exists as it does independent of any…
There was a time when a notebook and a pencil were sufficient tools for study in a classroom. In today’s world, students need much more to prepare themselves for the job market. The thing that has not changed is the impact a teacher can have on the life and learning of a student. Present education…

It was regarded as an unassailable island due to its strong seaward defenses. Singapore’s defenses were concentrated at their naval base in order to…
Since, the time of Sir Isaac Newton, the mysterious force of gravity has intrigued many physicists for centuries. The classical anecdote of the apple falling on Newton’s head led Newton to propose that some mysterious force must be pulling that apple downwards. While this was a great leap forward in the field of physics, Newton…
The properties of light have been understood by physicists to be completely fundamental to our understanding of the universe, however defining these properties have proven difficult to elucidate. What is light? What is light composed of? Does light obey classical physics? These questions are important to answer when considering physical phenomena that involve light. One…
Supernovae can occur in two different and distinct ways. One of the ways in which a supernova can be triggered is through the instantaneous ignition of a nuclear fusion reaction in a degenerate star (star at end of it’s life). For example, a white dwarf, in a binary system, may accumulate material from that companion…
Black holes are regions of space-time that prevent anything, including light, from escaping. The reason for this is that black holes are extremely dense and so the escape velocity required to escape the black hole must be huge. It should be made clear that a black hole is a distortion of space-time (Einstein had described…

The law holds people responsible for putting themselves in a state of intoxication and for the consequences of their actions while in this state.…
Purpose: The purpose of the lab was to dissolve Copper salt in water with an excess of Aluminum. The mass of the Copper formed was to be determined and the percentage yield was to be calculated.

Ever since the first explorers came to Canada, their goal was to expand culture and gain wealth for their mother country. When the British won/took the french colonies, they tried to build on what France had already done. The outcome to this, that still exists is a flourishing French population where the French colonies had…
