10 Important Questions To Ask Before Using iPads in Class Digital Tools Teaching Strategies Lenny Gonzales By Terry Heick When it comes to deciding how or whether to use iPads, schools typically focus on budget issues, apps, networking logistics, check-in and check-out procedures, school and district tech-use policies, hardware precautions, and aspects of classroom management. But it’s also important to think about instructional use, and to that end, consider the following questions. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Also worth considering: How can parents, families, and local businesses be involved in procuring, managing, or integrating iPads in the classroom? These kinds of questions can help you get the most out of the iPad’s use in your classroom. This post originally appeared on TeachThought, where Terry Heick is the director of curriculum.

Athletics Circular motion is common to almost all sporting events. Whether it is sports car racing or track and field, baseball running or ice-skating, the motion of objects in circles is a common observation of sports viewers around the world. Like any object moving in a circle, the motion of these objects that we view from the stadium bleachers or watch upon the television monitor are governed by Newton's laws of motion. Their circular motion - however brief or prolonged they may be - is characterized by an inward acceleration and caused by an inward net force. Making the Turn The most common example of the physics of circular motion in sports involves the turn. Because turning a corner involves the motion of an object that is momentarily moving along the path of a circle, both the concepts and the mathematics of circular motion can be applied to such a motion. In the case of the speed skater above, the force resulting from the contact between ice skates and ice has two components to it. it.
DiracDelta Science & Engineering Encyclopedia High School Engineering Science News What Students Can Actually DO With An iPad Online, in workshops, and even with friends, I frequently get asked What can the iPad actually do? as a sort of challenge to the worth of the device. I would rather that they ask, What can you actually do with an iPad? So last week, in preparing for the New England Reading Association Conference and the NYSCATE Mobile Learning Summit , I decided to change my approach. However, before addressing that question, I asked not only WHY iPads but WHY Technology ? I want my students to communicate in complex and modern ways. What does this tangibly look like in the classroom? I want my students to demonstrate their knowledge of the parts of a story. Learning Objectives: In addition to learning the story elements, students learn… To write a constructive review To assess the credibility of an author or source To create a sense of visual hierarchy for their information To document their sources Project: Book Posters – students create a movie-style poster to advertise their book.
How to build a real 'Star Wars' lightsaber The idea behind a lightsaber is simple genius: a light-weight and immensely powerful tool that uses a blade of energy to not only slice up disciples of the Dark Side in a single blow but also act as an effective shield against laser blasts. So why don't we have working lightsabers in real life? Surely physicists must be smart enough (and big enough Star Wars fans) to be able to produce one of these incredible objects. The obvious way of building a lightsaber would be to use a laser, which can be seen as a particularly bright and directional burst of light. But even though laser technology is continuously striding towards more efficient and practical machines, we are still miles away from a working lightsaber. The first challenge is making the blade of your lightsaber an acceptable size, let's say around three feet or so. One solution could be to place a small mirror at the tip of the blade. Passing the baton. But all is not lost. Anyone got a light?
