CONCEPT CHECKERSĬoncept Checkers were built to coordinate with the Physics Interactives section of our website. Task Tracker also allows teachers to assign problems to their students and track their progress. ![]() Teachers with Task Tracker accounts can modify problems and problem sets and even create their own problems. Most problems are accompanied by an audio-guided solution that explains how to solve a similar problem while hilighting the habits that can be adopted for solving any problem. An answer box allows students to solve and check their answers. Numerical information is randomly-generated. Our newest version includes >2500 Physics and Chemistry problems organized into >250 ready-to-use problem sets. Version 2 of the Calculator Pad is now available. There is a fully functional free version and a paid version that integrates seamlessly with our Task Tracker system and offers some rather enticing features. Version 5 is our best-yet version of Minds On Physics. "MOPs" combines interactive questioning modules with a thorough, question-specific Help system to engage students in an exercise in thinking, reflecting and learning. Minds On Physics - Version 5 is the HTML5 version of Minds On Physics that replaces our App and Legacy versions. Relying on a large bank of carefully crafted questions, Minds On Physics seeks to improve students' conceptions of physics. And for Chemistry types, we've added a large collection of Chemistry Concept Builders. Perfect for students and 1:1 classrooms using iPads, Chromebooks, and the like. Filled with interactive elements, this section is the perfect tool for getting students thinking about the meaning of concepts. Have you tried a Concept Builder lately? You should. This growing collection of cognitively-rich exercises will focus student attention on discrete learning goals. Each animation is accompanied by explanations and links to further information. MULTIMEDIA PHYSICS STUDIOSĪ large collection of GIF animations and QuickTime movies designed to demonstrate physics principles in a visual manner. Or subscribe to our YouTube channel, tap the bell, and receive notifications when new videos come out. We add videos quite frequently so stop back by if you don't find what you are looking for. Watch them on our site or follow the links to YouTube. We aim to present relatively short, highly-organized presentations with a strong graphical component on discrete topics. Our Video Tutorial provides a video-based alternative to the written Tutorial above. Designed with tablets such as the iPad and with Chromebooks in mind, this user-friendly section is filled with skill-building exercises, physics simulations, and game-like challenges. ![]() ![]() The Physics Interactives includes a large collection of HTML5 interactive physics simulations. An ideal starting location for those grasping for understanding or searching for answers. Step 3.A set of instructional pages written in an easy-to-understand language and complemented by graphics and Check Your Understanding sections.c) Combine these redox couples into two half-reactions.b) Identify and write out all redox couples in reaction.a) Assign oxidation numbers for each atom.Separate the redox reaction into half-reactions When these two conditions are met, the equation is said to be balanced. Also the sum of the charges on one side of the equation must be equal to the sum of the charges on the other side. This means that a chemical equation must have the same number of atoms of each element on both side of the equation. The Law of Conservation of Mass states that mass is neither created nor destroyed in an ordinary chemical reaction. If the elements in a chemical formula are properly capitalized, the smart case converter leaves them as you have typed.Ī balanced chemical equation accurately describes the quantities of reactants and products in chemical reactions. The equation can be written in lowercase letters.To enter the equation sign, you can use either "=" or "->" or "→" symbols.To enter charge species, just type them as they are, for example Hg2+, Hg22+, or Hg2^2+.All types of parentheses are correct, for example K3. ![]() Spaces are irrelevant, for example Cu SO 4 is equal CuSO4.Enter an equation of a chemical reaction and click 'Submit' (for example: mn2++bio3-+h+=mno4-+bi3+ ).
