World Sunlight Map Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness. The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted. Compare this with Peters, Mollweide or equirectangular projection maps. Also available is a semi-realistic view of dawn and dusk from far above the Earth, a look at the moon, and information about how this works.
Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5. schoolphysics ::Welcome:: Bestsellers Bestsellers The books below are a selection of the bestselling titles available from ASE Publications, for the full selection of titles in the ASE Bookshop click here. ASE members enjoy significantly lower prices for all ASE Publications! Analysing Practical Science Activities to Assess and Improve their Effectiveness This booklet presents a method for analysing practical activities to provide a clear description of their principal features. This analysis provides a basis for considering the effectiveness of a practical activity, and for thinking about how it might be modified to improve it. Be Safe! The ONLY publication that gives advice on both safety in primary school science and practical science and technology in primary schools across the UK.

Exploratorium RESISTOR COLOR CODE CALCULATOR As can be seen in the above 4 Band Resistor Color Codes chart, the first two color bands have values of brown = 1, red = 2, orange = 3 and so on. The third color band is the multiplier of the first 2 bands. Here, black is 1, brown is 10, red is 100 and so on. Putting this in other words, the value of the third band (the multiplier) is the number 10 raised to the power of the color code. For example, red in the third band is 10² or 100. This third band also has 2 new colors where gold = .1 and silver = .01. The 4th band is the resistor's tolerance and shows how precisely the resistor was manufactured. Now that we know the values of each color, let's try calculating a few examples of resistance values. Looking at resistor #1, we see the colors red red green gold. Resistor #2 has the colors orange orange yellow silver which "translates" into 3 3 ×10,000 or 330,000 ohms and a tolerance of 10%. Five Band Resistors Use the 5 Band Chart to solve these next problems. Resistors In Parallel
Mindsets online European Science Foundation Fears, Rules, Words, Questions « Teaching Science A quick lesson description here; I’ve been far too focused on political stuff recently. I thought I’d blogged this before, but apparently not. (And while I’m reviewing – 120 posts. Yeah, really.) Anyway. It’s the time of year, after summative exams for our KS3 classes, that we teach Reproduction to year 7. Stop giggling at the back there! This is my approach to starting off what can be a challenging topic. Fears “What might make a student nervous about this topic?” Rules I remind the students of the rules we have agreed and followed all year. Words I write ‘F***’ on the board, with asterisks, and explain over the gasps and giggles that we all know which word this is. I then circle the ‘polite’ words and explain that we can consider these as ‘classroom English’. Important: clean the board very thoroughly. :) Questions I give each student a piece of paper and ask them to spread out, as if doing a test. Comments? Like this: Like Loading...
