Web 2.0 Science Tools By Laura Turner The following web2.0 sites would be useful for science educators at the high school and middle school level. Some would also be appropriate for higher elementary grade levels. Defy Gravity! Centripetal Force According to Newton's law of inertia, an object already moving will continue to move in a straight line at a constant speed unless acted on by an outside force. Thus, to make an object move in a circular path, an outside force must act on the object. Centripetal force is the force that pushes or pulls an object inward so that it will move in a circular path. The word centripetal means to seek the center. When you whirl a stone tied to a string in a circle, you must constantly pull on the string to keep the stone from flying off in a straight line.
The Earth and Beyond Welcome to The Earth and Beyond Hello, my name is Tim O'Brien. I'm an astronomer working at The University of Manchester's Jodrell Bank Observatory. As an astronomer my job is to try and understand how the universe works and my main interest is why some stars explode - more about this later! I also get to visit lots of schools and share amazing facts with children and teachers about the Sun, Earth and Moon, the stars and planets, and the Universe as we know it!
Fun Sites for Primary Pupils - Science General Sites BBC Science Clips 36 interactive resources linked to the QCA Scheme of Work for Science - ideal for use with an interactive whiteboard. Life Processes and Living Things The Great Plant Escape Help Detective LePlant and his partners Bud and Sprout unlock the amazing mysteries of plant life! They will need your help to find clues, do experiments, and solve problems as you journey into the world of plants. Newton's Third Law of Motion: Astronauts in Outer Space One of NASA's first attempts at a "space walk" turned into an exhausting failure for astronaut Gene Cernan. Unlike astronauts who had "walked" in space on previous missions, Cernan had several tasks to accomplish outside the spacecraft. However, every time he attempted to push or turn a valve, he was sent hurtling in the opposite direction, with little control over his trajectory. After many exhausting minutes, his mission outside the capsule was called off, and NASA scientists began trying to figure out what went wrong. NASA scientists and engineers should probably have predicted that if an astronaut applied force to open or close a valve, the valve would apply the same amount of force to him, but in the opposite direction. After all, nearly 300 years ago, Isaac Newton presented what came to be known as his third law of motion, which says that for every action there is an equal and opposite reaction.
Jamie's Ministry of Food "I want to inspire you to get in the kitchen and cook meals for yourself and your family from scratch, whether you're a complete beginner or a good cook who likes simplicity. With some basic skills under your belt and a handful of recipes, you'll be able to prepare nutritious meals on any budget." Jamie Oliver Phantom island, Treasure maps A research team on board Australia’s Marine National Facility research vessel, Southern Surveyor, have made an unusual discovery: an island that isn’t there. We rely on maps all the time. Street directories and websites such as Google Maps help us to find our way around unfamiliar places, and help prevent us getting lost. Carnival Physics: Midway Games Two common carnival games, "Break the Plate" and "Knock the Blocks off the Table," require energy (the ability to do work or make changes to the physical world) to win. Where does that energy come from? The energy comes from you, the player.
Healthy Eating Welcome to the Healthy eating module for children aged 5-8 years. This module supports primary school children learning about healthy eating, as depicted by the eatwell plate and is comprised of a comprehensive Teachers' Guide and three Key Facts; Key Fact 1 - Food is a basic requirement for life; Key fact 2 - People choose different types of food; Key Fact 3 - We all need to eat a variety and balance of food to stay healthy, as depicted in the eatwell plate. The Key Facts are the key messages and skills children need to know and ensure that children's learning is coherent and progressive.
