To perform experiments safely and correctly, students should know about different apparatus and their uses.
1. Beaker
๐งช Use: Holds and measures liquids, heats substances.
๐ Example Experiment: Mixing vinegar and baking soda to observe chemical reactions.
2. Test Tubes
๐งช Use: Holds small amounts of liquids for heating, mixing, or testing.
๐ Example Experiment: Growing crystals or observing color changes in chemical reactions.
3. Measuring Cylinder (Graduated Cylinder)
๐ฌ Use: Accurately measures liquid volume in milliliters (mL).
๐ Example Experiment: Measuring water displacement to find the volume of an irregular object.
4. Dropper/Pipette
๐ง Use: Transfers small amounts of liquid drop by drop.
๐ Example Experiment: Adding drops of lemon juice to baking soda to observe fizzing.
5. Funnel
๐ป Use: Helps pour liquids into containers without spilling.
๐ Example Experiment: Filtering dirty water to demonstrate water purification.
6. Microscope
๐ฌ Use: Magnifies tiny objects like cells and microorganisms.
๐ Example Experiment: Observing onion skin cells or tiny insects.
7. Bunsen Burner
๐ฅ Use: Heats substances for experiments.
๐ Example Experiment: Heating sugar to observe caramelization.
โ ๏ธ Caution: Always handle with supervision!
8. Thermometer
๐ก Use: Measures temperature of liquids and air.
๐ Example Experiment: Checking temperature differences between hot and cold water.
9. Spring Balance
โ Use: Measures force or weight in Newtons.
๐ Example Experiment: Measuring the weight of different objects to understand gravity.
10. Magnifying Glass
๐ Use: Enlarges small objects for easy observation.
๐ Example Experiment: Examining leaves, insects, or tiny details on objects.
11. Stopwatch
โฑ Use: Measures time accurately.
๐ Example Experiment: Timing how long different materials take to sink in water.
12. Litmus Paper
๐ Use: Tests acidity and alkalinity of substances.
๐ Example Experiment: Testing lemon juice (acid) and soap water (base).
13. Tongs & Forceps
๐ง Use: Holds hot or small objects safely.
๐ Example Experiment: Handling hot test tubes during heating.
