Study Notes
Integrated Science - Form 1 Exam Study Notes
Lab Safety, Home Safety, and School Safety
- Lab Safety: Adhere to safety regulations in labs; wear appropriate protective gear (e.g., goggles, lab coat).
- Home Safety: Practice safe behavior at home; avoid hazards like exposed wires, sharp objects, and kitchen appliances.
- School Safety: Follow school rules; be aware of safety protocols; report any incidents to teachers or staff.
- Emergency procedures: Know fire drill protocol, earthquake drill and other safety procedures.
- First aid: Knowledge of basic first aid is crucial in case of minor injuries.
- Reporting hazards: Responsibility to report safety hazards promptly in all settings.
Lab Equipment
- Beaker: Used for mixing and heating liquids.
- Flask: Used for storing and mixing liquids or gases.
- Test tube: For holding small amounts of substances during experiments.
- Bunsen burner: Used for heating substances.
- Graduated cylinder: Used to measure volume. (Pictures would be highly effective here)
- Thermometer: Measures temperature.
- Microscope: Used to magnify small organisms or structures.
- Balances: Used for precise mass measurements.
- Pipette: used to transfer small quantities of liquids.
- Funnel: Used to transfer liquids to containers with small openings.
Use of Meter Ruler
- Units of measurement: Meters, centimeters, millimeters are used to measure length.
- Reading scales: How to accurately read markings on a ruler.
- Estimating measurements: Estimating lengths and using the ruler to make precise measurements in centimeters and millimeters.
Scientific Method, Variables, and Hypothesis
- Scientific Method: Observations, forming questions, creating hypotheses, testing hypotheses, collecting data, drawing conclusions.
- Independent Variable: The variable that is changed or manipulated by the experimenter.
- Dependent Variable: The variable that is observed and measured to see how it changes in response to the independent variable.
- Control variables: Variables kept constant in an experiment to ensure that the results are due to the independent variable.
- Hypothesis: A testable statement that explains an observation or answers a scientific question.
- Experiments: Procedures to test validity of the hypothesis.
