+ Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
+ The periodic table is organized like a big grid. Each element is placed in a specific location because of its atomic structure. As with any grid, the periodic table has rows (left to right) and columns (up and down). Each row and column has specific characteristics. For example, magnesium (Mg) and calcium (Mg) are found in column two and share certain similarities while potassium (K) and calcium (Ca) from row four share different characteristics. Magnesium and sodium (Na) also share qualities because the are in the same period (similar electron configurations).

+ Using computers and the internet to store, access and organise information carries some risk. You need to take responsibility to make sure files are not lost, corrupted or viewed by the wrong person.
+ To ensure your work is easy to find, use relevant file and folder names and a sensible folder structure. It’s important to use an approach that will be understood by everyone, especially if you’re working on a group project, so other members of the group will be able to find what they’re looking for.Files have two parts to their names – a name and an extension. The purpose of a file extension is to tell the computer what type of file it is. The file extension is typically three or four letters long and is always at the end of a file name. There are hundreds of different file extensions. Passwords can be set to expire, at which point you will be forced to choose a new one. This is a security feature. Always choose a password that’s difficult for someone else to guess.

+ Can you multiply by two-digit numbers like 14 or 37?. It looks a bit difficult, doesn't it? It can be easier if you partition the number into two parts. Instead of multiplying by 29 you can multiply by 20 and then multiply by 9 separately and then add the answers together. Instead of multiplying by 34 you can multiply by 30 and then multiply by 4 separately and then add the answers together.
+ Another strategy is to multiply by a near number that is easier to work with and then add or take away the difference. Was that easier? Why not try these strategies again next time you have to multiply by two-digit numbers.
