Learning Intention: Students will understand that the pH scale ranges from 1 (acid) to 7 (neutral) to 14 (basic). They will understand that acids release a hydrogen ion in solution and alkaline substances release an hydroxide ion. Substances can be tested using an acid-base indicator such as litmus paper or purple cabbage indicator. The colour [...]

Chemical Reactions – Rusting
March 25th, 2013 · No Comments · Chemistry, Year 8
Learning Intention: Students will understand that rusting is another type of chemical reaction, in which the products of the reaction are different to the reactants. They will also learn about the process of planning and conducting an experiment, devising an hypothesis and using a control with variables. Success Criteria: Students will plan and conduct an experiment [...]
Making Paper from Grass

The Carbon Cycle
March 1st, 2013 · No Comments · Biology, Chemistry, Year 8
Created using Comic Life Learning Intention: Students will understand the processes involved in the carbon cycle – photosynthesis, respiration, decomposition, combustion and fossil-fuel formation. Success Criteria: A product that demonstrates their understanding by providing an explanation of each of these processes. Your assessment task for this unit of work is to produce an artefact that [...]
Elements and Compounds
February 26th, 2013 · No Comments · Biology, Chemistry, Year 8
Image Source So far this year, you have learned about the following: An atom consists of positively charged protons and neutrons with no charge in a nucleus in the centre of the atom and much smaller electrons, which are negatively charged and on the outside of the atom. Molecules are tiny particles made up of [...]
Year 8 Science: Atoms and Molecules
February 2nd, 2013 · No Comments · Chemistry, Year 8
Learning Intention: Students will be able to recognise the structure of atoms and molecules and understand some of the features of the periodic table. They will know that elements are pure substances made up of a single type of atom. Success Criteria: You will be able to define atoms, molecules, elements and compounds. You will be [...]
Chemical Energy

Exothermic and Endothermic Reactions
April 19th, 2012 · No Comments · Chemistry, Year 9
Image Source Learning Intention: Students will understand the meaning of exothermic and endothermic reactions. Success Criteria: Students will be able to identify exothermic and endothermic reactions and give examples of each. They will be able to explain why these processes to considered to be exothermic or endothermic. Endothermic reactions absorb energy, causing a decrease in temperature [...]
