Quickwrite #4 + Practice & Review in Density
- 1. Today in Science You will Need: 1)Pencil, Calculator 2)Practice & Review– 1 page 2 sides 3)Quick Write #4
- 2. Test #1-Retakes 1. 1 opportunities to retake 2. Monday at lunch 3. Same content/different tests 4. No notes; just a calculator
- 3. Quick Writes will not be grade for points but for participation and honesty. 1. You are allowed to use your brain, any notes, labs or worksheets we have done in class. 2. You may not use your textbook or interactive reader. 3. You will have 10 minutes to complete as many questions as possible. 4. With a colored pencil, you will grade your own.
- 4. 1. Identify the type of numbers you have. (unit labels) Whenever you work a density problem…. Look to see what numbers you are given. You identify the numbers by their unit label. Once you know what numbers you have you can determine which formula to use. SOMETIMES you will need to first find the VOLUME before using a density formula. Mass Unit Labels = any gram amount Volume Unit Labels = cm3, cc, mL Density Unit Labels = g/cm3, g/cc, g/mL
- 5. 2. Understand what the problem is asking. Carefully read through the problem to understand what is going on… 1.Are they asking you to find displacement? 2.Are they asking you to find the volume of a cube? 3.Or…are you given enough variables to use one of the density formulas?
- 6. 3. It is a one step problem or two step problem? Remember: You may need to find volume first before using a density formula.
- 7. 4. Which formula should you use? Once the numbers (variables) you are given in a problem have been identified you need to determine which formula to use. D = m/v V = m/D m= v x D
- 8. 1. Identify the type of numbers you have. (unit labels) 2. Understand what the problem is asking. 3. It is a one step problem or two step problem? 4. Which formula should you use?
- 9. Task List 1) Work to complete Practice and Review This sheet is part of Lab we will start on Monday…not due until Wednesday
- 10. Homework 1)None- Unless you owe me something 2)Enjoy your weekend!
