Question

1. measurements in science. length, mass, volume. what are the measurement tools, units, symbols? draw pictures of each

Explanation:

Length:

• Tool: Ruler (or meter stick, tape measure). A ruler has markings for units like centimeters (cm) and millimeters (mm) or inches. For example, a standard 30 - cm ruler has markings every 1 mm (smallest) and 1 cm (larger).
• Unit (Metric): Meter (m), centimeter (cm), millimeter (mm), kilometer (km). In the imperial system, inch (in), foot (ft), yard (yd), mile (mi).
• Symbol: For metric, \(m\) (meter), \(cm\) (centimeter), \(mm\) (millimeter), \(km\) (kilometer). For imperial, \(in\) (inch), \(ft\) (foot), \(yd\) (yard), \(mi\) (mile).

Mass:

• Tool: Balance scale (like a triple - beam balance) or electronic scale. A triple - beam balance has a pan on one side and weights on the other, with a pointer to indicate balance. An electronic scale shows the mass digitally.
• Unit (Metric): Gram (g), kilogram (kg), milligram (mg), metric ton (t). In the imperial system, ounce (oz), pound (lb), ton (imperial ton).
• Symbol: \(g\) (gram), \(kg\) (kilogram), \(mg\) (milligram), \(t\) (metric ton); \(oz\) (ounce), \(lb\) (pound), \(ton\) (imperial ton).

Volume:

• Tool: Graduated cylinder (for liquids), measuring cup (for liquids or solids like granular materials), volumetric flask (for precise volume in labs). A graduated cylinder has markings for milliliters (mL) or liters (L) along its side.
• Unit (Metric): Liter (L), milliliter (mL), cubic meter (\(m^3\)), cubic centimeter (\(cm^3\) or \(cc\)). In the imperial system, fluid ounce (fl oz), cup, pint, quart, gallon.
• Symbol: \(L\) (liter), \(mL\) (milliliter), \(m^3\) (cubic meter), \(cm^3\) (cubic centimeter); \(fl\ oz\) (fluid ounce), etc.

(Note: For drawing pictures, a ruler can be drawn as a long rectangle with markings, a triple - beam balance as a base with a pan, a beam with sliding weights and a pointer, and a graduated cylinder as a tall, narrow cylinder with volume markings on the side.)

Answer:

Length:

• Tool: Ruler (meter stick, tape measure)
• Units (Metric): Meter (\(m\)), Centimeter (\(cm\)), Millimeter (\(mm\)), Kilometer (\(km\)); (Imperial: Inch (\(in\)), Foot (\(ft\)), Yard (\(yd\)), Mile (\(mi\)))
• Symbols: \(m\), \(cm\), \(mm\), \(km\) (or \(in\), \(ft\), \(yd\), \(mi\))

Mass:

• Tool: Triple - beam balance, Electronic scale
• Units (Metric): Gram (\(g\)), Kilogram (\(kg\)), Milligram (\(mg\)), Metric Ton (\(t\)); (Imperial: Ounce (\(oz\)), Pound (\(lb\)), Imperial Ton (\(ton\)))
• Symbols: \(g\), \(kg\), \(mg\), \(t\) (or \(oz\), \(lb\), \(ton\))

Volume:

• Tool: Graduated Cylinder, Measuring Cup, Volumetric Flask
• Units (Metric): Liter (\(L\)), Milliliter (\(mL\)), Cubic Meter (\(m^3\)), Cubic Centimeter (\(cm^3\)); (Imperial: Fluid Ounce (\(fl\ oz\)), Cup, Pint, Quart, Gallon)
• Symbols: \(L\), \(mL\), \(m^3\), \(cm^3\) (or \(fl\ oz\), etc.)

(For drawings, represent the ruler with markings, the balance with a pan and weights, and the graduated cylinder with volume markings.)
