![]() ![]() This is because of a specific algorithm that Google uses in order to sort through and figure which websites are the most important, based on relevance and website rank. However, more often than not, you never have to venture off that first page of results, because the most important and relevant items are on that first page. For example, usually when you search for something on Google, there are many results, even pages and pages of results. Algorithms can be used to sort a large set of information based on a set of structural rules, such as step by step instructions. This way, you spend less time looking for posts that you might be interested in. For example, Instagram uses an algorithm which determines which posts to show you at the top of your feed, based on your browsing habits. Well-built algorithms help optimize time by finding and programming the quickest path to get something done. ![]() O Scientists and engineers have to make use of their time wisely. Repeat steps 2-4 until correct order is achieved.If so, swap the second and third number.Is the second number larger than the third number?.Is the first number larger than the second number?.Look at the numbers in the order that the user entered them.The program could then follow a set of specific steps in order arrange the numbers from smallest to largest. For example, a user of a computer program could be asked to enter in 3 random numbers. In the realm of computer science, algorithms are a specific set of instructions and operations that a computer program carries out to accomplish various tasks. Put very simply, algorithms are a set of step-by-step instructions. People use algorithms all the time in their daily routines for accomplishing tasks, such as brushing your teeth, or making a sandwich! The word ‘algorithm’ might seem scary at first, but it is actually a straightforward concept. There are many factors that go into the extensive process of making our modern-day technology possible, but one important tool that scientists and engineers use are algorithms. In a digitally dependent world, who are the magicians behind the scenes making all of this technology possible? The answer is scientists and engineers. PowerPoint Presentation Script (pdf) Visit [ to print or download. Understand what a website network is, and the relative importance of websites.Explain what algorithms do and how they are useful to us.Students will learn how valuable creating a sufficient algorithm can be for engineers, as well as the accuracy involved with algorithms.Īfter this lesson, students should be able to: Google, in particular, engineered an algorithm which helps everyday people find specific information, quickly. Engineers use algorithms to sort through large sets of data, in order to find critical information more quickly. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Ĭomputer scientists and engineers design and implement algorithms to make specific jobs easier and faster to perform. We then discuss Google’s PageRank algorithm for ranking the importance of websites based on the other websites that link to them, and play a fun game that can be used to find the same results as the PageRank algorithm. We start by engaging students with very simple examples of algorithms which they can associate with. This lesson is intended to get students interested in the inner workings of algorithms and the capabilities associated with them. Algorithms are one of the foundations of our technological world, and are driven by the scientists and engineers behind the scenes that write all of these different algorithms. ![]()
