TCAP Review Copy the underlined text Science Notes The A B Cs of 8th grade science 16) D- DMV (Dept of Motor Vehicles) Density=mass divided by volume 17) D- DMV to MVD (mass = volume x density) 18) D- DMV to VDM (volume = density divides mass) V= density mass
Science TCAP Review Notes 16) D- DMV (Dept of Motor Vehicles) Density=mass divided by volume 17) D- DMV or MVD (mass= volume x density) 18) D- DMV or VDM (volume=density divides mass)V= density mass • What is density? • Density is the amount of matter (mass) • you have crammed in a given space (volume) • The unit for mass is grams (mg or g or kg) • Unit for solid volume is cubic meters (cm3 or m3 or km3) • Unit for liquid volume is liters (mL or L or kL) • Units for density is g/cm3 or g/mL • To compute density • - divide the mass by the volume of the object
SPI 0807.9.7 Density Notes Science Use this formula: Density = mass divided by volume M V D= M/V or or D= Example: The mass of an object is 30g and the volume is 10cm3 What is the density? Do the math: 30 (mass) divided by 10 (volume) Density= volume mass 3 Density= 10 30 Units… g/cm3 - 30 0 Density= 3 g/cm3
SPI 0807.9.7 Density Notes Science A different formula: Not DMV…instead use MVD Mass = Volume x Density M= V x D Example: The volume of an object is 10cm3. The density of the object is3 g/cm3 What is the mass? Do the math: 10 (volume) times 3 (density) Mass= 10 x 3 Units… grams Mass= 30 g
SPI 0807.9.7 Density Notes Science A different formula: Not DMV…instead use VDM Volume = Density divides the Mass V= D M Example: The density of an object is 3 g/cm3. The mass of the object is30 g. What is the volume? Do the math: 30 (mass) divided by 3 (density) Volume= 3 30 10 Units… cm3 Volume= 10 cm3 - 30 0
Science TCAP Review Practice The A B Cs of 8th grade science Now let's practice from memory with some prompts Density Mass Divided Volume 16) D- Hint: DMV _______ = _____ _______ by _______ 17) D- Hint: DMV to MVD ____ = ______ x _______ 18) D- Hint: DMV to VDM _______ = ________ _______ _____ Bonus: Write the formula for VDM with the division dog house Hint: Volume = _____________ Mass Volume Density Volume density divides mass Density Mass
