where it is easily accessed by the students. Common misconceptions with students regarding decimals may stem from the ideas that longer is larger or smaller is larger. A common misunderstanding is when students compare numbers by separating the decimal numbers, creating two whole numbers on each side of the decimal. However, this misconception may be hard to recognise as an educator as sometimes it may result in a fluke answer. Example: Which is Smaller? Incorrect Reasoning Correct Reasoning…

I am researching the element, boron. The symbol of boron is a just a capital B. The atomic number of boron is 5. Boron’s mass is 10.811 grams. Boron has 5 protons, 6 neutrons, and 5 electrons. The Periodic Table lists elements in numerical order from the smallest atomic number to the largest atomic number. That is why boron is the 5th element on the Periodic Table. It comes after beryllium and before carbon. Boron was discovered on June 30th in 1808. It was discovered by French chemists,…

How are elements useful for a particular use? An element is made from one type of atom and this article is about the element Scandium. Scandium was discovered in the year 1879 by Scientist Lars Fredrik Nilson in the university of Uppsala. The origin of the name comes from the word Scandia, which is the latin name for Scandinavia. This element belongs to group 3 which consists of transition metals and Scandium shares this group with the element Yttrium. There are 4 groups in the periodic table…

student will start to develop their place value knowledge once they are confident using number names, classifying objects, identifying patterns and as they begin to develop their counting skills. From Year 1, the Australian Curriculum expects students to count collections to 100 by partitioning numbers using place value (ACARA, 2016). This means students need to learn about grouping in tens and that two-digit numbers are made up of tens and ones. Booker, Bond, Barrow and Swan (2014, p. 87)…

which was the first printed account of what we know now as coordinates or analytic geometry (C.H. Edwards). In many books he wrote, Descartes wrote very small alphabets in front of numbers which suggests his use of variables and constants. He also created the use of superscripted numerals to depict the powers of a number or quantity; Descartes occasionally wrote aa for the second power, a2. In addition to these wonderful contributions, Descartes also utilized geometry to find the slope of the…

This mechanism is source in the formation of boundary layers and is highly sensitive to the Reynold’s number. At low Re values, frictional drag influences the nature of attached flows around a bluff body. In contrast, pressure drag is attributed to motion produced by eddies generated in the flow at higher Re values, but is less sensitive to the Reynold’s number. It is important for separated flows and is associated with the formation of the wake following a bluff body. For streamlined…

of all numbers: The dictionary meaning of prime is ‘Of first importance’ or ‘Of the best quality, excellent’ etc. What is so great about prime numbers? A number is said to be a prime if it is divisible only by 1 and itself. 5, for example, is a prime number because it is divisible only by 1 and 5. The number 4 can be divided by 1, 4 AND 2. So it is not a prime number. Numbers that are not primes are said to be composite numbers. The fundamental theorem of Arithmetic states that all numbers are…

pipe at high velocities. The type of flow whether its laminar, transitional or turbulent solely depends on the Reynolds number, Re value. When the Reynolds number, Re is less than 2000, it is considered as laminar flow whereas Reynolds number, Re between 2000 to 4000 is referred as transitional flow and for turbulent flow, the Reynolds number should be more than…

Computational Fluid Dynamics Computational fluid dynamics (CFD) is the simulation of fluids in engineering systems using modeling such as mathematical physical problem formulation and numerical methods like discretization methods, solver, numerical parameters and grid generation. Computational fluid dynamics is based on the concept of Reynolds averaging of the unsteady Navier-Stokes equation commonly known as (RANS) which are considered by Leishman to be the most adaptable method for…

How incredible to think that this temptation is so great that the Lord will send down a flying angel to communicate this message to the people on earth. This speaks to the Lord’s awesome grace and love towards all humanity. He does not long for the death of anyone’s soul, but that they should repent and believe (Ezek. 33:11). Death of the soul is not annihilation, but everlasting torment. Humanity’s mythic stories of good and evil draw upon this real battle that culminates in real…
