Science Year 2

Learning Outcomes - Interaction within Ecosystems 1. Show an understanding of an ecosystem as the interactions between a community (biotic factors) and its physical environment (abiotic factors). 2. Explain the importance of various physical/ abiotic factors such as air, water, temperature, light, minerals and acidity/ alkalinity to the survival of organisms. 3. 4. Investigate an environment using measuring instruments such as the data-logger and probes to collect data on physical factors such a

Learning Outcomes: Interactions - Chemical Changes 1. a. Deduce the chemical formulae of common monatomic ions using the Periodic Table. b. State the chemical formulae of common polyatomic ions (i.e. hydroxide, nitrate, sulfate, carbonate). c. Deduce the formulae of ionic compounds from the charges on the ions present and vice versa. d. Deduce the formulae of simple covalent substances from the relative numbers of atoms present and vice versa. 2. Identify a change that leads to the formation of
