| Lesson Topic: Name appropriate apparatus for the measurement of time, temperature, mass and volume, including: (a) stopwatches (b) thermometers (c) balances (d) burettes (e) volumetric pipettes (f) measuring cylinders (g) gas syringes |
Learning Objective/s:
- Identify and name the appropriate apparatus for measuring time, temperature, mass, and volume in chemical experiments.
- Explain the correct usage, calibration and reading techniques for each piece of equipment.
- Demonstrate how to select the most suitable apparatus for a given experimental requirement and record measurements with appropriate precision.
|
Materials Needed:
- Digital stopwatches
- Thermometers (mercury or alcohol)
- Analytical and top‑loading balances
- Burettes, volumetric pipettes and measuring cylinders
- Gas syringes with tubing
- Safety goggles and gloves
- Worksheet with apparatus‑matching activity
- Projector for demonstration images
|
Introduction:
Begin with a quick demonstration of a stopwatch timing a simple reaction to capture students' interest. Review prior knowledge of the four fundamental quantities measured in labs and discuss why accurate measurement matters. Explain that by the end of the lesson they will be able to name each apparatus, describe its correct use, and choose the right tool for a given experiment.
|
Lesson Structure:
- Do‑now (5') – Students list the four quantities and write any apparatus they already know.
- Mini‑lecture (10') – Overview of each apparatus with projector images, highlighting key features and accuracy.
- Guided practice stations (20') – Small groups rotate through stations with stopwatches, thermometers, balances, burettes/pipettes, measuring cylinders, and gas syringes, completing a checklist.
- Data recording exercise (10') – Using a worksheet, groups record sample measurements and calculate significant figures.
- Whole‑class discussion (10') – Groups share which apparatus they would select for specific experimental scenarios; teacher checks understanding.
- Quick quiz (5') – Exit ticket with three short questions on apparatus identification and correct usage.
|
Conclusion:
Summarise the main points: each apparatus measures a specific quantity and must be used with proper calibration and reading technique. Ask students to complete an exit ticket naming one piece of equipment and its key use. For homework, assign a short worksheet matching experimental tasks to the appropriate apparatus.
