This investigation involves a web quest and simulation to help students learn about the make-up and functioning of semiconductors as well as some applications. They will learn about p and n type materials, the pn junction, and what happens when an outside EMF source is added.
Students will learn and analyze basic water irrigation methods
In this activity, students conduct an investigation to purify water. They engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment. Through this activity and its associated lesson, student teams follow the steps of the engineering design process related to water treatment, as done by practicing engineers, including constructing and testing their designs.
To better understand electricity, students investigate the properties of materials based on their ability to dispel static electricity. They complete a lab worksheet, collect experimental data, and draw conclusions based on their observations and understanding of electricity. The activity provides hands-on learning experience to safely explore the concept of static electricity, learning what static electricity is and which materials best hold static charge. Students learn to identify materials that hold static charge as insulators and materials that dispel charge as conductors. The class applies the results from their material tests to real-world engineering by identifying the best of the given materials for moving current in a solar panel.
The goal of this activity is to understand how techniques of persuasion (including background, supporting evidence, storytelling and the call to action) are used to develop an argument for or against a topic. Students develop an environmental case study for presentation and understand how a case study is used as an analysis tool.
Students will brainstorm ways that they use and waste natural resources. Also, they will respond to some facts about population growth and how people use petroleum. Lastly, students will consider the different ways that engineers interact with and use our natural resources.
The aim of this video lesson is to teach students about the different topologies of computer networks and how they function. The approach that is used is highly correlated with common knowledge about weddings and the local Malay culture associated with weddings. Students should be able to relate the act of delivering food to a large crowd of people to the basic principles of network topologies and the method of data transfer within each type of topology. The lesson will begin in a classroom with students working in small groups, answering assigned questions. Teaching aids such as color cards will be used. One student from each group will be appointed as the wedding event manager, and she/he will have to discuss and act out with group members in order to answer more challenging questions. At the end of the lesson, students will be asked to come up with their own version of a hybrid computer network topology. The lesson concept taught here not only educates students on computer topologies, but also introduces students to an important cultural perspective of Malaysia. Above all, this video is designed to assist students with their study of Computer Literacy in schools. The lesson will take up to 60 minutes to complete. Materials needed include: 10 red cards representing waitresses; 10 green cards representing waiters; 10 blue cards representing tables in the hall; a sketch book; and classroom tables and chairs.
In this activity, students will conduct a survey to identify the environmental issues (in their community, their country and the world) for which people are concerned. They will tally and graph the results. Also, students will discuss how surveys are important when engineers make decisions about environmental issues.
In this activity, students will learn to identify different opinions related to an issue as well as the things (information, values and beliefs) that influence those opinions. They will use an opinion spectrum to analyze the range of opinions in their classroom on environmental issues and understand how these spectrums can be valuable to engineering design.
In this activity, students learn how to prevent exposure to the Sun's harmful ultraviolet rays. Students will systematically test various sunscreens to determine the relationship between spf (sun protection factor) value and sun exposure. At the end of the activity, students are asked to consider how this investigation could be used to help them design a new sunscreen.
Student teams model the Earth's greenhouse effect using modeling clay, ice chunks, water, aluminum pie tins and plastic wrap. They observe and record what happens in this closed environment and discuss the implications of global warming theory for engineers, themselves and the Earth.
Students investigate potential energy held within springs (elastic potential energy) as part of the Research and Revise step. Class begins with a video of spring shoes or bungee jumping. Then students move on into notes and problems as a group. A few questions are given as homework. The Test Your Mettle section concludes. The lesson includes a dry lab that involves pogo sticks to solidify the concepts of spring potential energy, kinetic energy and gravitational energy, as well as conservation of energy.
Students learn about complex networks and how to use graphs to represent them. They also learn that graph theory is a useful part of mathematics for studying complex networks in diverse applications of science and engineering, including neural networks in the brain, biochemical reaction networks in cells, communication networks, such as the internet, and social networks. Students are also introduced to random processes on networks. An illustrative example shows how a random process can be used to represent the spread of an infectious disease, such as the flu, on a social network of students, and demonstrates how scientists and engineers use mathematics and computers to model and simulate random processes on complex networks for the purposes of learning more about our world and creating solutions to improve our health, happiness and safety.
Students explore the concept of "reducing" solid waste and how it relates to product packaging and engineering advancements in packaging materials. They read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. Then they evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. In addition, students explore "hydropulping" and consider its use as a recycling process.
This lesson will introduce students to environmental issues. Students will recognize environmental opinions and perspective, which will help them define themselves and others as either preservationists or conservationists. Students also learn about the importance of teamwork in engineering.
Students identify types and sources of indoor air pollutants in their school and home environments. They evaluate actions that can be taken to reduce and prevent poor indoor air quality. In an associated literacy activity, students develop a persuasive peer-to-peer case against smoking with the goal to understand how language usage can influence perception, attitudes and behavior.
Student groups use the Java programming language to implement the algorithms for optical character recognition (OCR) that they developed in the associated lesson. They use different Java classes (provided) to test and refine their algorithms. The ultimate goal is to produce computer code that recognizes a digit on a scoreboard. Through this activity, students experience a very small part of what software engineers go through to create robust OCR methods. This software design lesson/activity set is designed to be part of a Java programming class.
Student teams are challenged to design models of Egyptian funerary barges for the purpose of transporting mummies through the underworld to the afterlife. Planning the boat designs requires an understanding of ancient culture and beliefs so the mummies are transported safely through the perils of the underworld. Students design and build prototypes using materials and tools like the ancient Egyptians had at their disposal. Then they do the same with modern materials and techniques, forming an awareness of the similarities and differences of the barge designs between the ancient materials and tools (technologies) and today's technologies, which are evolved from the earlier ways.
