Definition: How long Equipment: meter stick or ruler Units: meters (m) Hint: start at zero on the ruler

Definition: Amount of matter in an object Equipment: Triple Beam Balance Units: grams (g) Hints: Put the weight in the groove

Definition: Amount of space an object takes up Equipment: Graduated cylinder, beaker or ruler Units: liters(L) or cubic centimeters (cc or cm 3 ) Hints: read from the bottom of the meniscus (curved water line)

Definition: Average kinetic energy of an object Equipment: Thermometer Units: degrees Celsius ( O C) Hints: 30 = hot, 20 = warm, 10 = cool, 0 = cold

Definition: How long a task takes Equipment: stopwatch or clock Units: seconds or minutes Hint: reset stopwatch every time

Definition: how much mass is in a given volume Equipment: triple beam balance (for mass) and a ruler or graduated cylinder (for volume) plus a calculator (it’s a calculation – not a measurement!) Units: g/ml or g/cm 3 Hints: mass/volume m (looks like a heart) v

Density of water = 1 g/ml Any object less than 1 g/ml will float Any object greater than 1 g/ml will sink

1. Write the formula: Density = mass/volume 2. Show your work 3. Answer with units Example: What is the density of a rock that has a mass of 10 grams and a volume of 2 ml? Formula: Density = mass/volume Show your work: 10 g/ 2 ml Answer with units: 5 g/ml

What is the density of a 500 kg rock that’s volume is 100 cm 3 ? 1.Write the formulaD = m/v 2.Show your workD = 500kg/100 cm 3 3. Answer with unitsD = 5 kg/cm 3
