Science Area of Key Knowledge Points STILE Review Study Physics Static electricity ❏ The structure of the atom: subatomic particles, including protons, neutrons & electrons Student Electricity booklet ❏ The electron has a negative charge and is loosely held surrounding the nucleus of an atom ❏ Insulators are materials that do not allow electrons to easily flow through it ❏ Objects that lose electrons become positively charged; objects that gain electrons become negatively charged Good Science textbook ❏ Opposite charges attract; like charges repel Chapter 6 6.1 Electrical energy Current electricity 6.2 Energy in circuits 6.3 Ohm’s Law ❏ A conductor is a material that allows electrons to easily flow through it 6.4 Making electric circuits ❏ Electric circuit basics: load, power supply & conducting wires 6.5 Series & parallel circuits ❏ Must know circuit component symbols ❏ Key terms include: ❏ Current (I), measured in amperes or amps (A) Assessment tasks: ❏ Voltage (V), measured in volts (V) 1. Practical task setting up a ❏ Resistance (R), measured in Ohms (Ω) series circuit ❏ Resistor colour code 2. Data analysis task, for ohmic ❏ Circuits: know the characteristics for each e.g. how do V and I compare? & non-ohmic devices. ❏ Series, where all components are in one conducting path OR ❏ Parallel, there are two or more conducting paths ❏ Describe brightness of bulbs in series and parallel circuits ❏ Short circuits, when the resistance is close to zero ❏ Ammeter: used to measure current (set up in series) ❏ Voltmeters: used to measure voltage (set up in parallel) ❏ Correctly position and read resistors, voltmeters and ammeters in both series and parallel circuits. ❏ Apply Ohm’s Law to a range of different V, I and R values ❏ Graph voltage and current onto a set of axes with the correct labels and units. ❏ Calculate the gradient on a voltage vs current graph ❏ Identify if a device is ohmic or non-ohmic General Stages in an Investigation Science ❏ Planning Skills ❏ Conducting ❏ Communicating STILE: “Conducting Science Investigations” Report Components ❏ Title/Question ❏ Aim ❏ Hypothesis ❏ Method & Materials ❏ Safety ❏ Results ❏ Tables ❏ Graphs ❏ Analysis, Trends, Discussion, Evaluation, Limitations & Improvements ❏ Conclusion Definitions: ❏ Accuracy VS Precision ❏ Reliability ❏ IV - Independent Variable ❏ DV - Dependent Variable ❏ CV - Controlled Variables ❏ Qualitative (observation) and Quantitative (values/measurements) data ❏ Control group
