The web is full of photos, and even videos, that are digitally altered. And it's often hard to tell the difference between what's real and what's fake. Help your students ask critical questions about why someone might alter a photo or video in the first place.
In past times, ocean navigators tossed a piece of wood over the side of their ships and noted how long until the ship passed the wood. They used this time measurement and the length of the ship to calculate their speed and estimate how far they had traveled. In this activity, students act the part of a GPS signal traveling to the receiver to learn how travel time is converted to distance.
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.
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.
Students build model sets of lungs.
Students journal their thoughts and responses to the questions associated with the grand challenge question presented in the associated lesson. For the Generate Ideas" step, they answer the questions: "What are your initial ideas about how this challenge can be answered? What background knowledge is needed? Have you tried this before?" After students have individually written responses to these questions, the class brainstorms together to reach consensus on the main ideas that need to be explored to solve the challenge question.
Social interaction is part of what makes online gaming so popular and engaging for kids. Of course, online communication can come with some risks. Show your students how to keep their gaming experiences fun, healthy, and positive.
Keys To Your Future is designed to empower high school students to make informed, goal-oriented decisions about their future, and provide students with the skills they need to reach their goals. This course includes career exploration, informs students about a variety of post-secondary educational pathways to pursue, and equips students with the practical knowledge of how to prepare for, and apply to, college and/or jobs.
Compare the effects of different strengths or different directions of pushes and pulls on the motion of an object and determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.
Driving Question: Can I as “Science Investigator”, engineer and design,
a way to move an object without using my hands or feet?
Students learn and use the properties of light to solve the following challenge: "A mummified troll was discovered this summer at our school and it has generated lots of interest worldwide. The principal asked us, the technology classes, to design a security system that alerts the police if someone tries to pilfer our prized possession. How can we construct a system that allows visitors to view our artifact during the day, but invisibly protects it at night in a cost-effective way?"
Launching Digital Writing in the Elementary Classroom tells the stories of seven teachers who were willing to take risks and venture into new territory by integrating technology into their workshops in meaningful ways.
During this activity, students will be introduced to the concepts of the challenge. They will generate ideas for solving the grand challenge first independently, then in small groups. Finally, as a class, students will compile their ideas with a visual as a learning supplement.
Learning to Learn Online helps you prepare for online learning success by introducing you to the online learning environment and your role as a learner within it. As you come to understand yourself as an self-directed learner, you will also be introduced to effective learning strategies: time management for online learners, information management, professional communication, and reading strategies. Welcome to your online learning journey!
In a very hands-on activity, students observe and feel the differences between two cleaning methods, with and without hand soap, using coffee grounds to represent "dirt."Most of the dirt and bacteria on our hands is encased in a thin layer of oil, so because of the properties of oil and water, cleaning your hands with water alone has little effect when trying to remove the dirt. This activity demonstrates the importance of using a surfactant, such as hand soap, when washing your hands.
With so much information at our fingertips, students learn what it means to "give credit" when using content they find online. Taking on the role of a detective, students learn why it's important to give credit and the right ways to do it when they use words, images, or ideas that belong to others.
Students work as biomedical engineers to find liquid solutions that can clear away polyvinyl acetate polymer "blood clots" in model arteries (made of clear, flexible tubing). Teams create samples of the "blood clot" polymer with different concentrations to discover the concentration of the model clot and then test a variety of liquids to determine which most effectively breaks down the model blood clot. Students learn the importance of the testing phase in the engineering design process, because they are only given one chance to present the team's solution and apply it to the model blood clot.
This video discusses the various ways in which academic libraries and their librarians are supporting the Open Education Movement.
Students examine various materials to investigate how they interact with light. They use five characteristicsâtranslucency, transparency, opaqueness, reflectivity and refractivityâto describe how light interacts with the objects.
