  1. Bell Work Apr 14, 2014 TCAP Review • Take out a clean sheet of paper, and write your heading on it. • Number your paper from 1 to 15, and begin • 1) A- Argon… • 2) A- Acids… • 3) A-Acids… • 4) A- 1st letter is…, so the… • 5) B- Bases… • 6) B- Bases… • 7) B- B is for… • 8) B- B is for… 9) C- compounds come from… 10) C- chem reactions form… 11) C- Cx3: count the… 12) C- chem reactions can HOPE… 13) C- chem reacts can 3FPC… 14) C- Control experiments are for… 15) C- Constants do not…

  2. Notes Science TCAP Review • Here are the correct answers in order. • 1) A- Argon is the ____________________ in our atmosphere • 2) A- Acids=______________ ions • 3) A-Acids are ___________ on the pH Scale • 4) A- The 1st letter is ___, so the _____ numbers are… • …A for _____ • 5) B-Bases= ______________ ions • 6) B- Bases are _____________ on the pH Scale • 7) B- B is for _________ numbers & B is for _______ • 8) B- B is for ________ and B is for _____ color 3rd most common gas hydronium Zero to 6.9 A 1st acids hydroxide 7.1 to 14 bigger bases bitter blue

  3. Science Notes TCAP Review The A B Cs of 8th grade science Here are the rest of the answers in order 9) C- C= C, ____________come from _____________________. 10) C- _____________ form new ______________ 11) C- Cx3: ________ the capitals for ___________ 12) C- chem reactions HOPE (_____, _____, ____, _______ ) 13) C- chem reacts 3FPC (_____, ____ , _____ , __________, _____) 14) C- ________ experiments are for ____________ 15) C- __________ do not change compounds chemical reactions chem reactions substances count compounds heat odor pop explode fizzle foam precipitate color flash control comparison constants

  4. 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

  5. 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

  6. 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

  7. 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

  8. 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

  9. 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
