Knock Hardy KNOCKHARDY PUBLISHING produces notes and other resources for AS and A2 Level Chemistry. The module references are for the AQA and OCR examinations but the material applies equally well to other specifications. The pages are saved as PDF files and may be freely read and printed for personal use but they may not be revised or circulated in any other form without the consent of Knockhardy Publishing.

AQA – GCSE Additional Science GCSE Additional Science offers students a broad, coherent course of study that adds to their knowledge and understanding of the living, material and physical worlds. For Key Stage 4 (KS4) learners it is a good follow on from GCSE Science A or B. The three core Sciences of Biology, Chemistry and Physics are taught separately using Unit 2 modules from the individual subject GCSEs. This specification allows subject specialists to teach the appropriate units focussing on their area of expertise, or it can be taught by an integrated Science teacher. Teachers can choose between two routes: three separate exams in Biology, Chemistry and Physics together with a controlled assessment, ortwo combined exams plus the controlled assessment. It is suitable for students of all abilities and helps students to understand theoretical concepts alongside developing practical science skills. Specification Amended due to Changes to GCSEs.

REACTIONS What is a chemical reaction? Examples of chemical changes, physical changes, and some gray areas. Chemical equations of chemical reactions.Balancing equations. Balancing ionic equations with polyatomic ions. Balancing combustion (burning) equations. A chemical reaction is material changing from a beginning mass to a resulting substance. A chemical equation is a way to describe what goes on in a chemical reaction, the actual change in a material. Back to the top of Reactions. Chemical reactions, also called chemical changes, are not limited to happening in a chemistry lab. A silver spoon tarnishes. Ag2S An iron bar rusts. 2 Fe2O3 Methane burns. An antacid (calcium hydroxide) neutralizes stomach acid (hydrochloric acid). CaCl2 + 2 H2O Glucose (simple sugar) ferments to ethyl alcohol and carbon dioxide. 2 C2H5OH (ethyl alcohol) + 2 CO2 Alcohol plus oxygen becomes vinegar and a molecule of water. Here are some examples of changes that are NOT chemical reactions. _ Ag+ (NO3)- + _ Ca2+ Cl-2 Easy.

HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network. Part of the intent for this exploration environment is to provide many opportunities for numerical exploration in the form of active formuli and standard problems implemented in Javascript. New content for HyperPhysics will be posted as it is developed. A resource that was initiated as a resource for local high school physics teachers whom I had taught has expanded into an intensively used website worldwide. CD or DVD versions have been sent to 86 countries to date, and translations into German, Italian, Chinese, and Español have been licensed and are underway. HyperPhysics (©C.R.
The Virtual Lab Series BioInteractive’s virtual labs have won several awards, including top honors in the Pirelli INTERNETional Award competition, which recognizes the best multimedia products designed to use the Internet to educate about science and technology. Designed in close consultation with educators and scientists, these virtual labs are fully interactive biomedical laboratory simulations and provide students with skills and techniques used in scientific research. BioInteractive’s series of virtual labs allows students to examine heart patients, analyze DNA sequences, probe the nervous system of a leech, use human antibodies to diagnose disease, and measure physical traits of stickleback fish and anole lizards to examine key concepts in evolution. Each lab provides an interactive environment in which students perform experiments and collect their data, and answer questions to assess their understanding. The labs can be accessed by clicking the icons on the right-hand side of the page.
