Secret Worlds: The Universe Within - Interactive Java Tutorial Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it. Earth = 12.76 x 10+6 = 12,760,000 meters wide (12.76 million meters) Plant Cell = 12.76 x 10-6 = 0.00001276 meters wide (12.76 millionths of a meter) Contributing Authors David A.
The Physics Classroom The Energy Story Energy is one of the most fundamental parts of our universe. We use energy to do work. Energy lights our cities. Energy powers our vehicles, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories and tractors on a farm. Energy from the sun gives us light during the day. Everything we do is connected to energy in one form or another. Energy is defined as: "the ability to do work." When we eat, our bodies transform the energy stored in the food into energy to do work. Cars, planes, light bulbs, boats and machinery also transform energy into work. Work means moving something, lifting something, warming something, lighting something. There are many sources of energy. The forms of energy we will look at include: Electricity We will also look at turbines and generators, at what electricity is, how energy is sent to users, and how we can decrease or conserve the energy we use.
Difference Between Isotopes and Isobars Isotopes vs Isobars Atoms are the small building blocks of all existing substances. There are variations between different atoms. Also, there are variations within the same elements. Isotopes are examples for differences within a single element. Isotopes Atoms of the same element can be different. 1H – no neutrons, relative abundance is 99.985% 2H- one neutron, relative abundance is 0.015% 3H- two neutrons, relative abundance is 0% The number of neutrons a nucleus can hold differs from element to element. A mass spectrometer can be used to get information about isotopes. Isobars Isobars are atoms of different elements with the same mass number but their atomic numbers are different. Related posts:

Free online Absorb resources You can now access hundreds of free whiteboard resources taken from our Absorb courseware, Search Resources Why are they free? We're doing this to help get Absorb known. Can I use them in my own lessons? Yes! in Powerpoint presentations, with whiteboard software such as Promethean ActivStudio or SMART Notebook, on your school intranet, on your Moodle site or other VLE. Home | Practical Physics Find out about our education projects and free teaching resources from the links on this page. We also offer opportunities for school and college students to take part in STEM-related research over their summer holidays through our Nuffield Research Placements. Our work in education includes funding research and supporting its translation into policy and practice. Our current focus is in science and mathematics, foundations for learning, and secondary education transitions. In the past, we have worked in other subject areas including D&T, history, and languages, and further information is available on our curriculum projects page.
ippex online - main Physics 121.6 Applets The following is a list of applet collections that you may find useful. In the table above however I have links to a few of the many applets available on the web that I think are most useful in illustrating the concepts of this course. Applets 1 - Graphs of Position and Velocity This Applet shows a cow on roller skates! You can give the cow an initial position, an initial velocity and an initial acceleration and then you can see what happened when you click on "RUN". Note the shape of the position vs. time graph and the velocity verses time graph for each of the following cases. Try different non-zero initial velocities with zero acceleration. This second applet displays much the same thing. Run Applet... Applets 2 - Vector Addition This Shockwave applet shows the addition of two vectors (Red vector + Green vector = Blue vector). Run Applet... Another applet which shows much the same thing in a slightly different way.... Run Applet... Applets 3 - Projectile Motion Run Applet...
