SI System (metric system) Scientific Measurement SI System (metric system) Grams (g, kg, mg) Liter (L, mL, mm3 , cm3) g/mL, g/cm3, g/L, kg/L Density < 1.00 g/mL will float Density > 1.00 g/mL will sink Mass The amount of matter in an object Volume The space an object takes up Density Amount of matter in a given volume Mass/volume

Scientific Measurement Length Temperature How hot something is. How much energy does something have. Meters (m, mm, cm, km) Celsius (Centigrade) Kelvin ( K )
