Pyrotechnics Student summary Skycolour   FACTS KEYWORDS CONCEPTS I can understand that… Evidence  The atoms in an element are all the same.   Different elements have different appearances and properties because they have different atoms. Compounds are made up of atoms from two or more elements joined together. The name of a compound indicates the elements of which it is made up and the formula shows the number of each atom. During chemical reactions the particles rearrange to make new substances. The products of a reaction have different properties from the reactants. FACTS I can remember… Substances can be changed permanently in chemical reactions. The Periodic Table lists all the elements and their symbols. The symbols of some common elements. The formula of some common compounds. QUESTIONS I can answer… Evidence  How can solid silver appear from a liquid? Why do certain words appear repeatedly in chemical names? How can you decide what substances are elements? SKILLS I know how to… Safely handle laboratory equipment and chemicals. Identify elements and compounds in particle pictures. Decide if a formula represents an element or a compound. Identify the elements present in simple compounds from their names. Predict the name of the compound made when two elements react. Interpret the meaning of a chemical formula in terms of the number and type of atoms. Describe chemical reactions in terms of particle pictures or word equations. KEYWORDS atom chemical reaction compound element formula metal molecule non-metal Periodic Table 1

Pyrotechnics Student summary Reveal   FACTS KEYWORDS CONCEPTS I can understand that… Evidence  Chemical reactions follow patterns that can allow you to predict the products of an unknown reaction.   Word, symbol equations and particle pictures can be used to describe chemical reactions. Symbol equations show the relative amounts needed for compounds to react. The total mass of the products in a chemical reaction is always the same as the total mass of the reactants. FACTS I can remember… pH describes the acidity of a solution Metal oxides are alkaline and non-metal oxides are acidic. Acids and alkalis neutralise each other when they are mixed in the right ratio. The general reaction of acids with metals and acids with carbonates. The test for hydrogen and the test for carbon dioxide. Reactants and products can be gases. QUESTIONS I can answer… Evidence  How can you make a neutral solution? How can you predict the products without carrying out the reaction? SKILLS I know how to… Handle chemicals and equipment safely. Use Universal Indicator to decide pH. Test for hydrogen and carbon dioxide. Write simple word equations. Match products to the reactants they could form. KEYWORDS acid alkali carbonate carbon dioxide equation hydrogen limewater metal neutral neutralisation pH squeaky pop 2
