4434Fourier: Making Waves - Quantum Mechanics, Harmonic Motion, Wavelength
https://www.merlot.org/merlot/viewMaterial.htm?id=1196910
Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves. This simulation of a Fourier: Making Waves is from the Physics Education Technology website of University of Colorado. Included are links to related topics and additional ideas and activities for teachers to use.Mon, 18 Jul 2016 12:34:16 -0700The Vortex Flowmeter
https://www.merlot.org/merlot/viewMaterial.htm?id=1196874
This Web site features a series of animations showing the operation of a vortex flowmeter that is used to measure flow in a process control system. Besides defining a vortex flowmeter, a Flash animation shows how it causes vortices around a blunt object obstructing the flow. A sine wave flow is created depending upon the flow velocity. After viewing several pages, a brief two question quiz is given with self-correcting answers.Mon, 18 Jul 2016 12:33:30 -0700Reroofing Your Uncle's House
https://www.merlot.org/merlot/viewMaterial.htm?id=1195344
In this interactive activity adapted from the Wisconsin Online Resource Center, students will "use mathematics and measuring skills to solve a construction problem." They will determine how many shingles are required to rerroof a house using common tools, and learn about the importance of planning and calculating necessary materials. The material is intended for students in grades 9-12. The lesson is accompanied by a background essay, standards alignment and discussion questions. Users are encouraged to sign up for a free account.Mon, 18 Jul 2016 12:07:40 -0700Making Math and Science Skills Pay Off
https://www.merlot.org/merlot/viewMaterial.htm?id=1195342
The ATETV project delivers web-based videos to connect students to careers in advanced technology. In this episode of ATETV, laser and photonics technology, geospatial technology and alternative energy technologies are discussed. A strong background in math and science gives students an advantage in their community college programs. The skills learned in such programs translate directly to the field. Community colleges offer courses to help students improve their math and science skills if need be. The episode can be watched in full or through the three segments: "The Precision of Laser and Photonics Technologies," "Mapping the Coordinates of a New Career," and "Alternative Energies of the Future." Running time for the full episode of this streaming video is 9:25.Mon, 18 Jul 2016 12:07:38 -0700New Technologies Rely on Age-Old Skills
https://www.merlot.org/merlot/viewMaterial.htm?id=1195340
The ATETV project delivers web-based videos to connect students to careers in advanced technology. In this episode of ATETV, lasers and photonics technology, wind energy technology and the importance of mathematics are discussed. Technology being taught at community colleges, such as laser and photonics technologies, is in high demand in industry. Technological education relies heavily on math skills. Community colleges provide remedial math courses to help students improve their skills before moving on to more difficult applications of mathematics. The episode can be watched in full or through the three segments: "Shedding Light on Lasers," "Wind Power: A Growing Energy Source," and "It All Comes Back to Math." Running time for the full episode is 9:18.Mon, 18 Jul 2016 12:07:36 -0700Math Is More Than Just Numbers
https://www.merlot.org/merlot/viewMaterial.htm?id=1195336
The ATETV project delivers web-based videos to connect students to careers in advanced technology. In this episode of ATETV, viewers visit a community college prep class which is helping students improve their math skills. The instructor describes the importance of mathematics and how this class is structured to help students get caught up so that they can be successful in college. Running time for the episode is 4:50.Mon, 18 Jul 2016 12:07:33 -0700Mathematics at Work
https://www.merlot.org/merlot/viewMaterial.htm?id=1195316
The ATETV project delivers web-based videos to connect students to careers in advanced technology. In this episode of ATETV, students will see how important a strong foundation in mathematics is for those entering technical fields. This video would be particularly useful for students who struggle to see the importance of learning mathematics- they will get a glimpse at some of the real world applications of what they are learning. Running time for the episode is 2:55.Mon, 18 Jul 2016 12:07:12 -0700PhET: Estimation Game
https://www.merlot.org/merlot/viewMaterial.htm?id=1192885
This simulation provides practice on estimation of relative sizes. The user must estimate the relative lengths, areas, or volumes of objects. This activity builds student abilities to understand ratios and the scaling of sizes in different dimensions. It also includes a strategy section that teaches students how to visualize relative areas and volumes.Mon, 18 Jul 2016 11:26:49 -0700Adding Two Vectors
https://www.merlot.org/merlot/viewMaterial.htm?id=1192875
This website from David M. Harrison of the University of Toronto's physics department provides an animation of the addition of two vectors. Instructors may use this animation in explaining the concept of adding vectors and demonstrating the steps involved.Mon, 18 Jul 2016 11:26:38 -0700Statics - Trig: Pythagorean Theorem Calculations Using a TI-86
https://www.merlot.org/merlot/viewMaterial.htm?id=1190274
In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle. Target Audience: 2-4 Year College StudentsMon, 18 Jul 2016 10:15:30 -0700
