Study Notes
Measuring Length
- Length measures how long an object extends.
- Rulers, meter sticks/rods, and measuring tapes can measure length, width, height, and thickness.
- The meter (m) is the standard unit of length.
- Centimeters (cm) measure shorter lengths.
- Millimeters (mm) measure very tiny lengths.
- Kilometers (km) measure long distances.
- Example: A science book is 8 mm thick and 28 cm long.
- A standard road lane is 3.7 m wide.
- Units can be converted between larger and smaller scales.
- 1 km = 1000 m
- 1 m = 100 cm
- 1 cm = 10 mm
- The length of a bent pipe is measurable using a thread, which is then measured with a measuring tape.
Measuring Mass
- Mass indicates the amount of matter a substance holds.
- Determines how light or heavy an object is.
- Objects containing more mass are generally heavy.
- Kilogram (kg) is the standard unit of mass.
- Grams (g) and milligrams (mg) are used for objects with smaller masses.
- Kilograms (kg) and tons are used for objects with greater masses.
- Larger units of mass can be converted into smaller units.
- 1 ton = 1000 kg
- 1 kg = 1000 g
- 1 g = 1000 mg
- The blue whale is the world's heaviest animal, weighing up to 200,000 kg.
- Quintal is another unit of mass, where 1 quintal = 100 kg.
- A weighing machine measures the mass of objects.
- Different weighing machines exist for objects of varying mass.
- Lightweight or very heavy objects need specific weighing machines.
- Fruit and vegetable sellers use manual weighing machines.
- Weighing machines can measure the weight of gold, humans, and animals.
- Weighing machines are used in hospitals and laboratories.
- Digital weighing machines are used in laboratories.
- Weighing machines are used to weigh heavy vehicles.
Measuring Volume
- Volume or capacity refers to the amount of liquid a container can hold.
- The liter (L) is the standard unit of volume.
- Milliliter (mL) is used for smaller amounts of liquid.
- 1 liter = 1000 milliliters
- Measuring cylinders, beakers, and conical flasks measure liquid volume.
Instruments for Measuring Liquids
- Droppers
- Measuring cylinders
- Beakers
- Conical flasks
- Measuring cups measure milk or oil
Importance of Water
- Water is essential, and doctors recommend drinking about 2 liters daily.
- Adequate water intake maintains body temperature, increases energy, improves skin texture, and flushes out toxins.
Measuring Time
- Time measures the period between two events.
- a.m. stands for Ante Meridiem (before noon).
- p.m. stands for Post Meridiem (after noon).
- a.m. is used for morning time.
- p.m. is used for afternoon and night time.
- 12-hour and 24-hour clock systems exist.
- a.m. and p.m. are used in the 12-hour clock system.
- The 24-hour clock shows hours and minutes since midnight.
Units of Time
- 60 seconds = 1 minute
- 60 minutes = 1 hour
- 24 hours = 1 day
- 365 days = 1 year
- 10:25 a.m. means 10 hours and 25 minutes of a day.
