Science, Optics and You Table of Contents Science, Optics and You is a science curriculum package being developed for teachers, students, and parents. These activities are designed to promote the asking and answering of questions related to light, color, and optics. The program begins with basic information about lenses, shadows, prisms, and color, leading up to the use of sophisticated instruments scientists use to help them understand the world. The goal of Science, Optics and You is for students to acquire the skills with which they can do microscopic analysis of a variety of samples in multiple ways. Timeline in Optics - A summary of important events in optics, microscopy, astronomy, and the physics of light and color. Pioneers in Optics - Since the early days in Alexandria when Euclid described the laws of reflection in Optica, the science of optics has fascinated and challenged society's most brilliant minds.

MPM Liquid Demo Check out my blog! E-mail: Fluid Instructions: You can drag the fluid around with your mouse and adjust the sliders at the top to change the properties of the fluid in real-time. Check out my newest app: Grantophone! More cool demos! Please enable JavaScript to view the <a href=" About This is my implementation of the Material Point Method. For interpolation, I use the quadratic B-spline presented here: Analysis and Reduction of Quadrature Errors in the Material Point Method. Instead of integrating the density over time (which is what most of the MPM papers do), I do a density summation every frame. Material Parameters Some of these parameters are hard to explain in one or two sentences (and a couple I made up) so I'll also link you to their corresponding Wikipedia pages. Density - Target density for the particles. Stiffness - How compressible the fluid is. Bulk viscosity - Kind of like damping. Gravity - How much the particles will accelerate downwards.

The Blog of Phyz: Jearl Walker's Kinetic Karnival All six 30-minute episodes of Jearl Walker's classic television series, the Emmy-winning Kinetic Karnival, are available online at Walker's MySpace page. I recommend watching them before showing them in class, although I'm sure you'd do that anyway. There are a few brief moments that sensitive educators might find objectionable. Most of us find ways to work around such trivialities, but it's always best to be aware. I developed video question sets for episodes 1, 2, 3, and 5. Here's a one-stop collection of Kinetic Karnival links for your convenience. 1. 2. 3. 4. 5. 6.

The World's Darkest Substance: Vantablack | The Science Explorer What would you do if you were unable to see something that is right it front of you? No, you are not visually impaired, but you might be looking at a substance called Vantablack. This material is so black that it simply cannot be seen by the human eye. Our vision works by picking up reflected photons (light) from objects around us, which provides our brains with the source to construct the world we see. The substance Vantablack, however absorbs 99.9% of all light that strikes the substance. Therefore no photons are being reflected for our vision to pick up, which is why we are unable to see the substance. Our brains try to make sense of the situation, shading colors of other materials and objects around the Vantablack substance, and trying to provide us with something to observe. Check out this video by Nikola Slavkovic on Vantablack:

December 15 - On This Day in Chemistry | RSC He discovered radioactivity from uranium (U) salts and was awarded the Nobel Prize in Physics in 1903 along with Pierre and Marie Curie. Related Resources google Physics Materials – Physics! Blog! I am trying to find a way to easily share the materials that I use in my classes. They were originally based on physics Modeling Instruction with added parts borrowed from various sources, including Matt Greenwolfe among others. Contact me if you would like the files in a format other than PDF. I should also note that these are the materials I use with my students and that they are not a fully guided set of documents. Honors Physics My 2013 updates have tried to make the course a little tighter and sharper based on what my students were able to do last year.

Investigation Roadmaps - Motion Introduction STC Motion and Design is a 15-lesson kit intended for students in grade 5. It introduces students to the physics of motion and the importance of technological design. Big Ideas This kit is focused on both science content ideas and science process skills. Force as a push or pull More… Foundational Images Along with a variety of drawings, sketches, and multiviews, three of our foundational images are used in conjunction with the STC Motion and Design kit: Vectors , Particles and the Magnifier tool. To get a better idea of how some of these foundational images can be used in the classroom, refer to the Motion and Design roadmap below. Welcome to Color Matters - Table of Contents
