In this lesson, students will investigate error. As shown in earlier activities from navigation lessons 1 through 3, without an understanding of how errors can affect your position, you cannot navigate well. Introducing accuracy and precision will develop these concepts further. Also, students will learn how computers can help in navigation. Often, the calculations needed to navigate accurately are time consuming and complex. By using the power of computers to do calculations and repetitive tasks, one can quickly see how changing parameters likes angles and distances and introducing errors will affect their overall result.

Students analyze their social networks using graph theory. They gather data on their own social relationships, either from Facebook interactions or the interactions they have throughout the course of a day, recording it in Microsoft Excel and using Cytoscape (a free, downloadable application) to generate social network graphs that visually illustrate the key persons (nodes) and connections between them (edges). The nodes in the Cytoscape graphs are color-coded and sized according to the importance of the node (in this activity, nodes are people in students' social networks). After the analysis, the graphs are further examined to see what can be learned from the visual representation. Students gain practice with graph theory vocabulary, including node, edge, betweeness centrality and degree on interaction, and learn about a range of engineering applications of graph theory.

Introducing engineering concepts with Hour of Engineering website is an engaging way to get students thinking about a STEM future. Hour of Engineering is designed to inform and inspire students in upper elementary through high school about engineering. Helping your students build an innovation mindset with the adaptive tools to solve problems starts here!

By participating in the Hour of Engineering students will: Define STEM vocabulary; Display engineering literacy; Explore the engineering design process; Experiment with practical engineering skills; Solve real-world engineering challenges; Link concepts between science, technology, engineering, and math; Build engineering habits of mind like creativity, systems thinking, and collaboration.

There are three parts to the Hour of Engineering website: landing page with inspirational content, learning modules, and engineering design challenges. (1) The landing page features clickable items to inspire students about the connection between engineering, art, science, math and even music! Students can freely explore the videos and models to learn about each object before moving on to deeper learning. (2) Learning modules allow students to explore a specific engineering topic. Students can explore learning modules on their own or you can pair them with connected engineering challenges to guide a sequence of learning on a topic. (3) Engineering challenges are a gamified way for students to explore various topics, activities and objects within fields of engineering. Students participating in engineering challenges earn stars based on their interaction with learning elements. There are knowledge checks and interactive models for students to explore during a challenge.

In this lesson, students will learn how great navigators of the past stayed on course that is, the historical methods of navigation. The concepts of dead reckoning and celestial navigation are discussed.

College-level electrical engineering course highlighting numerical analysis for engineers. This course introduces students to the formulation, methodology, and techniques for numerical solution of engineering problems. Course features include suggested readings, lecture notes, assignment problems, and exams with solutions.

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers.

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

Students calculate compound interest to identify benefits of saving in interest-bearing accounts. They learn the "rule of 72" and apply it to both investments and debt. They learn that there is a relationship between the level of risk for an investment and the potential reward or return on that investment.

A detailed overview of the greenhouse effect, with explanations about Earth's atmosphere gases referred to as greenhouse gases, and the factors that influence the heat-trapping ability of a greenhouse. All information is reinforced through pictures, graphs, and learning activities. Learning activities give background, procedure, and assessment ideas.

After their carts collide in a hardware store, two teachers discover that they both bought the same items in different quantities. With limited information, this segment demonstrates how to use an equation to determine the cost of each item.

Students are introduced to calculus topics of limits, continuity, and derivatives, and gain a foundation of essential calculus skills.

Graph theory is a visual way to represent relationships between objects. One of the simplest uses of graph theory is a family tree that shows how different people are related. Another application is social networks like Facebook, where a network of "friends" and their "friends" can be represented using graphs. Students learn and apply concepts and methods of graph theory to analyze data for different relationships such as friendships and physical proximity. They are asked about relationships between people and how those relationships can be illustrated. As part of the lesson, students are challenged to find the social graph of their friends. This prepares students for the associated activity during which they simulate and analyze the spread of disease using graph theory by assuming close proximity to an infected individual causes the disease to spread.

Students will be making sense of problems and looking for structure in this lesson about real life rates and unit rates.

This unit teaches students how to become a wise consumer. Some of the topics discussed are income, budgeting, credit, saving, and loans. Five different activities include objectives, worksheets, evaluations, and resources.

Investigate the concepts of area, volume, 3D shapes, and nets using this interactive Learn Alberta math. The solid shapes focused on this exploration include rectangular and triangular prisms, rectangular and triangular pyramids, cylinders, and cones. Be sure to follow the link to the printable activities, solutions, learning strategies, and circle pong math game that are included to reinforce target skills. A video accompanies this resource to show real-life applications of the lesson's content.

This StudyCard set is a teaching activity that uses real-world contexts to assist students in understanding the concepts of maximum, minimum, increasing, and decreasing.

Students experience data collection, analysis and inquiry in this LEGO® MINDSTORMS® NXT -based activity. They measure the position of an oscillating platform using a ultrasonic sensor and perform statistical analysis to determine the mean, mode, median, percent difference and percent error for the collected data.

After conducting the associated activity, students are introduced to the material behavior of elastic solids. Engineering stress and strain are defined and their importance in designing devices and systems is explained. How engineers measure, calculate and interpret properties of elastic materials is addressed. Students calculate stress, strain and modulus of elasticity, and learn about the typical engineering stress-strain diagram (graph) of an elastic material.

Students obtain a basic understanding of microfluidic devices, how they are developed and their uses in the medical field. After conducting the associated activity, they watch a video clip and learn about flow rate and how this relates to the speed at which medicine takes effect in the body. What they learn contributes to their ongoing objective to answer the challenge question presented in lesson 1 of this unit. They conclude by solving flow rate problems provided on a worksheet.
