Minerals project. The Australian Schools Innovation in Science, Technology (ASISTM) project is part of the Australian Government's Boosting Innovation, Science, Technology and Mathematics Teaching (BISTMT) Programme which funds innovative projects that focus on improving teaching and learning in schools in the areas of science, technology and mathematics.These resources have been developed by the cluster schools as part of the ASISTM project. The Science and Minerals Schools Clusters project is one such ASISTM project run in partnership between the NSW Minerals Council and the Department Education and Training. As the context for this project was mining and minerals, two clusters of schools, representing government and non-government schools drawn from two mining regions, Illawarra and Orange, developed a range of resources for this project.

Summary Physical change is a change that alters the form or appearance of a material without changing the chemical composition. One example of a physical change is dissolving. Salt is made of ions that are ionically bonded together in a crystal. Sugar is made of molecules that are bonded together based on the positively and negatively charged areas. The positive and negative areas of water molecules are attracted to the oppositely charged ions in salt and to the positive and negative areas on sugar molecules. Because salt and sugar are made up of different atoms that bond together differently, water is attracted to them differently. That’s why solids that may look similar behave differently.

NASA ADS: Exploring How Different Features of Animations of Sodium Chloride Dissolution Affect Students' Explanations. SAO/NASA ADS Physics Abstract Service · Electronic Refereed Journal Article (HTML)· References in the article· Citations to the Article (8) (Citation History) · Refereed Citations to the Article· Reads History· · Translate This Page Abstract Animations of molecular structure and dynamics are often used to help students understand the abstract ideas of chemistry. This qualitative study investigated how the features of two different styles of molecular-level animation affected students' explanations of how sodium chloride dissolves in water.
In small group sessions 18 college-level general chemistry students dissolved table salt in water, after which they individually viewed two animations of salt dissolution. Before and after viewing each animation the participants provided pictorial, written, and oral explanations of the process at the macroscopic and molecular levels. Intermolecular Forces. Key Concepts Three types of force can operate between covalent molecules: Dispersion Forcesalso known as London Forces (named after Fritz London who first described these forces theoretically 1930) or as Weak Intermolecular Forces or as van der Waal's Forces1 (namd after the person who contributed to our understanding of non-ideal gas behaviour). Dipole-dipole interactions Hydrogen bonds Relative strength of Intermolecular Forces: Intermolecular forces (dispersion forces, dipole-dipole interactions and hydrogen bonds) are much weaker than intramolecular forces (covalent bonds, ionic bonds or metallic bonds) dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond). dispersion forces < dipole-dipole interactions < hydrogen bonds Dispersion Forces (London Forces, Weak Intermolecular Forces, van der Waal's Forces) Hydrogen bonds.
Breathing Places - Make a bug home. 50,000 (And Counting) Education Apps Worth Knowing About. You probably saw the title of this post and thought ‘okay there’s no friggin’ way he’s going to assemble a list of the best 50,000 education apps. But thanks to a partnership between Edudemic and FindTheBest , we’ve done just that. We’ve been working hard behind the scenes to build a robust directory of, as of this writing, about 56,000 education apps. But it’s not just a list… it’s a finely tuned directory capable of sorting out all the apps in ways not even available in the iTunes or Mac App stores. For example, you can now find out the average price of all education apps to see where your app falls. (Hint: the average price of an education app is $2.66) Note: there are literally tens of thousands of apps in this directory and some are better than others.
