Build an Atom - Phet
Topics Atoms Atomic Structure Isotope Symbols Atomic Nuclei Description Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Sample Learning Goals Use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge.Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass.Use the element name, mass, and charge to determine the number of protons, neutrons, and electrons.Define proton, neutron, electron, atom, and ion.Generate an isotopic symbol for an atom, given the number of protons, neutrons, and electrons.

JeLSIM Simulating Experiments Online This project grew out of a belief in the benefits of simulation, and a realisation that there is still some way to go if they are to achieve their full potential in online learning. We view the project as a chance to take a fresh look at the criticisms of simulation raised in education literature and as an opportunity to address them. A particular area of interest, is integration of simulations and assessment and the provision of "authentic" assessment where assessment is carried out in the environment in which learning takes place. The possibility of combining a proposal to UCLES to look at the above issues with one to suit the specific needs of the SQA within the PASS-IT project led to a focus on use of simulations in building up skills in practical activities and experimentation. A shortened version of the orginal proposal is available.

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. Rock Candy - 3 Tips for Growing Sugar Crystals Video Grow your own sugar crystals at home with this easy DIY chemistry experiment that's perfect for kids. Gather the few, simple ingredients and start experimenting today.See Transcript Hi, growing sugar crystals is a fun experiment, but it can be tough, so here are some tips to make sure your sugar crystals grow nice and big. A Simple Recipe As with any crystal growing project, it is important to make sure your solution is at adequate saturation levels. A good recipe for a crystal-growing solution is three parts sugar and 1 part water. Cool Down Slowly The best and fastest growing sugar crystals can be achieved if the solution cools down very slowly. Use clothes pins or a bag clip to suspend a long wooden dowel inside the container. Once your solution is cool, you may even move it into the refrigerator to further help crystallization. Common Trouble Spots If crystallization is too heavy, pour the solution into a fresh, clean container, and move your dowel to that container.

High School Physics and AP Physics Online Exploration Tools 3-D Angles Visualizing three-dimensional structures is a major hurdle for chemistry students. Compounding the difficulty, chemists use three different concepts to imply geometry, although there is no obvious geometric information in two of them. 3-D Angles uses pattern recognition principles introduced through rapid repeated exposure to three concepts to teach students to intuitively associate the three terms together in order to be able to correctly recognize the molecular structure from limited information. Current version 3.0 (October 19, 2010) System requirements Windows XP, Windows Vista, or Windows 7 Setup program 3-D_Angles_Setup.exe (2.94 MB) Note: If you run 3-D Angles and the program's display appears blank, you need to obtain updated video card drivers that support the OpenGL graphics library.
