NakedScientists's Channel This item has been hidden Science from the Sporran Play all Whilst tidying the Naked Scientists' office the other week the team unearthed this rather extraordinary collection of video reels featuring experimental scientist, Dr Ernest Otherford. We suspect he may be an ancestor of our very own Dave Ansell. It seems our forerunner had a penchant for exploring the laws of physics and chemistry using whatever happened to be in his sporran... 2:41 2:34 2:42 2:46 1:36 3:07 2:34 3:21 3:47 2:31 2:55 This item has been hidden This item has been hidden Science Toys Science toys help kids become interested in science, while also being a source of entertainment. They can plant the seeds for future scientific exploration and even a career in the sciences. In addition to being very educational, the right toy can mesmerize a child for hours as they learn how it works and figure out the nuances of its operation. It can definitely help give them that all important head start in school as they begin their studies in science. Science based toys are a great way to teach kids about basic scientific principles. Fortunately, I have done much of the investigative work for you and have made available many different toy listings at your finger tips. The science toys listed here are primarily physics based and altogether they enable kids of all ages to learn a lot about physics. I chose science toys which readily show a specific physical process, or processes, at work. Balancing Bird A plastic bird that is balanced by its beak (Main Concept: Center of gravity) Prism
Kemilektioner för grundskolan - Tolv månadsteman - IKEM Från och med hösten 2011 gäller nya kursplaner för grundskolan. Jämfört med tidigare är det nu tydligare vad barn ska lära sig när det gäller kemi och annan naturvetenskap. Barnen ska tillägna sig ett naturvetenskapliga arbetssätt. De ska kunna göra praktiska undersökningar, designa experiment som är rättvisa, ställa hypoteser et cetera. Kemilektionerna för grundskolan togs fram med anledning av att det år 2011 var Kemins år och är inspirerade av de teman som användes under kemiåret, teman som ville göra det tydligt att kemin finns överallt och att det inom de mest skilda samhällsfunktioner behövs kemisk kunskap. Huvudexperimenten i Kemilektioner för grundskolan är valda för att passa till årskurserna 4-6. Lektionerna är sammanställda av Bodil Nilsson, som har mycket kunskap om hur man intresserar barn för naturvetenskap och lång erfarenhet av att undervisa om didaktik och naturvetenskap på Lärarutbildningen vid Stockholms Universitet (tidigare Lärarhögskolan i Stockholm).
The Good Stuff The Good Stuff is a show featuring playlists of videos on a variety of different themes. The videos can be fictional, documentaries, educational, or whatever we think is interesting. We've covered topics such as Time, Recycling, Senses, Airplanes, and much more. Join Craig Benzine as he scours the depths of the universe and the inner recesses of the mind in a never-ending quest for the good stuff. Help support The Good Stuff by contributing on our Subbable page! music byDriftless Pony Club THE GOOD STUFF PLAYLISTSOrigins Head STEAM Familiar faces from YouTube channels, Head Squeeze and VSauce2, explain just what STEAM is all about and why you should care... STEAM stands for Science, Technology, Engineering, Arts and Maths and how these topics help us to do amazing things. Things like working out how our bodies function, creating the technology behind smart phones, or furthering telecommunications - heck, it's even behind how you can watch this video now. Our world is amazing, and so are people. Learning STEAM subjects could get you into all sorts of careers, from being an astronaut, an architect, a space plasma physicist, or even an engineer.
The Kids' Picture Show Looking for a kids' channel that's not too "kiddie?" Check out the Kids' Picture Show! Learn shapes, colors, numbers, the alphabet, communications skills and more with The Shapesters, Robot DJ, The Number Guys, My Fridge and the popular "What Shape Is It?" series. The Kids' Picture Show is an educational channel for toddlers, pre-schoolers, kindergarteners and elementary school-age students to learn language and life skills. Kids can explore speaking, listening and reading through poems, songs, flash cards, and lots of humorous videos. Great for all kids including reluctant learners, visual learners, ESL students and even children with developmental disabilities such as autism. Playlists:
Science definition - What is science? Science Definition The word science comes from the Latin "scientia," meaning knowledge. How do we define science? According to Webster's New Collegiate Dictionary, the definition of science is "knowledge attained through study or practice," or "knowledge covering general truths of the operation of general laws, esp. as obtained and tested through scientific method [and] concerned with the physical world." What does that really mean? The term science also refers to the organized body of knowledge people have gained using that system. The Science Store - Find fun and educational toys and gifts for kids, teens and adults. What is the purpose of science? Most scientific investigations use some form of the scientific method. Science as defined above is sometimes called pure science to differentiate it from applied science, which is the application of research to human needs.

Entalpiberäkningar Vi ska se hur man kan beräkna reaktionsentalpier på olika sätt och börjar med beräkning med hjälp av standardbildningsentalpier. Exempel 1. Beräkna förbränningsentalpin vid standardtillstånd och 25oC för förbränning av naturgas som vi antar består av metan. Reaktionsformel: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l) Lösning Ur tabell får vi bildningsentalpierna för reaktanter och produkter ΔHf0(CH4(g)) = -74,85 kJ/mol ΔHf0(O2(g)) = 0 kJ/mol ΔHf0(CO2(g)) = -393,5 kJ/mol ΔHf0(H2O(l)) = -285,8 kJ/mol Förbränningsentalpin är i detta fall samma som reaktionsentalpin och den får vi som skillnaden i bildningsentalpi mellan produkter och reaktanter. ΔHr0 = ΔHf0(CO2(g)) + 2 · ΔHf0(H2O(l)) - [ΔHf0(CH4(g)) + 2 · ΔHf0(O2(g))] = = -393,5 kJ/mol + 2 · (-285,8 kJ/mol) - [-74,85 kJ/mol + 2 · 0 kJ/mol] = = -890,25 kJ/mol Svar: ΔHc0 = ΔHr0 = -890,25 kJ/mol Exempel 2. CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l) Vi ser att reaktionen är exoterm och att värmeinnehållet minskar med 890,25 kJ/mol Exempel 3. CH4 + Cl2 → CH3Cl + HCl
