You now should know a few basics about chemistry: [br]That everything is made out of different substances with different properties like colour, taste and so forth.[br]These properties are used to find out more about the substances. At university there are a lot of different ways to further look at the properties of substances. If you want to learn more about the different methods of this so-called Analytic Chemistry, look at this link: https://en.wikipedia.org/wiki/List_of_chemical_analysis_methods [br][br]A chemical reaction is a process in which substances react with each other yielding a new type of compound.[br]If you want to learn more about different kinds of reactions, click on the following link: https://en.wikipedia.org/wiki/Chemical_reaction[br][br]Materials often aren't made of one substance but out of many.

Now you have to decide in which direction to continue![br][br]You can either decide to continue with "Acid and Bases" where you first have to extract a dye from red cabbage that you can use as an indicator in further experiments.[br][br]Or you can look at metals, ions and complexes where you first have to put iron filings into vinegar essence.[br][br]The choice is yours, don't get lost in the maze![br][br]Acids and bases: https://www.geogebra.org/m/rehr7kzr[br][br]Metals, ions and complexes: https://www.geogebra.org/m/mzrqnbcn[br][br]If you interested in plastics you can also look at the following link (warning, this will ultimately lead into the physics maze, beware!): https://www.geogebra.org/m/pgxnwvtr
