ANNOUNCEMENTS!• Homework: Calculating
Density Practice – due Friday
• Tutorials: Monday (Today!) after school
• Science Olympiad Club: Meets Today after school
• Friday Quiz: Be able to calculate density to identify an unknown
Grade Level Agenda1. Start working on Density? Diddy Did It. Show
all work and include units. – Example: D=m/v D= 10.0g/5.0mL D=2.0g/mL
2. Finish Density? Diddy Did It in class today
Measurement Practice• Watch the scale of each
graduated cylinder!– Is it 1.0mL?– Is it 0.1mL?– Is it 2.0mL?
• You may use a calculator for volume of a solid = l*w*h
• You may use a hand lens for the triple beam balances

Searching for Density Lab October 23-24 2013
:
Yellow- Materials Manager • Only person allowed out of seat during lab• Obtains and returns all lab materials
Blue- Safety/Clean-up Manager • Enforces all safety rules
Green - Activity Director • Reads directions to the group• Keeps group on-task
Red - Data Manager • Records all data • Ensures all group members have lab data
Ms. SmithMrs. MaloneMs. Cedillo
Searching for Density Lab• Describe your cylinders with
detail (translucent yellow cylinder, 3.7cm in length, shiny, rubbery solid, feels heavy for its size)
• Take accurate measurements – there is a right answer!
• Measure length in centimeters (cm) to one decimal place (Example: 3.7cm)
• Measure volume in milliliters (mL) to one decimal place (Example: 4.5mL)
• Measure mass in grams (g) to two decimal places (Example: 86.35g)
– 0.77 g/mL = Maple– 0.90 g/mL = Polypropylene– 1.15 g/mL Polyamide (Nylon)– 1.17 g/mL = Acrylic #1– 1.17 g/mL = Acrylic #2– 1.23 g/mL = Polyurethane– 1.32 g/mL = Phenolic– 1.37 g/mL = PVC #1– 1.37 g/mL = PVC #2– 1.37 g/mL = PVC #3– 2.2 g/mL = PTFE (Teflon)– 2.71 g/mL = Aluminum
