Presentation Transcript

  1. Density Water Displacement/ Practice

  2. Objective: • Today I will be able to: • Apply the water displacement method to calculating density • Correctly solve density problems • Informal Assessment – monitoring student questions and group interactions during the lab • Formal assessment – analyzing responses to the exit ticket, lab and practice problems • Common Core Connection • Make sense of problems and persevere in solving them • Attend to precision • Use appropriate tools strategically

  3. Lesson Sequence • Evaluate: Warm-Up • Explain: Methods for Calculating Density Notes • Engage/ Explore: Water Displacement lab • Elaborate: Density Practice Problems • Evaluate: Exit Ticket

  4. Warm - Up • Take out your lab from yesterday • Check off the lab self-assessment sheet to see how you did on the lab

  5. Objective • Today I will be able to: • Apply the water displacement method to calculating density • Correctly solve density problems

  6. Homework • Study for a Metric System/Dimensional Analysis/Accuracy and Precision Quiz Friday • Finish Density Practice Problems

  7. Agenda • Warm-Up • Methods for Calculating Density Notes • Water Displacement lab • Density Practice Problems • Exit Ticket

  8. Methods for Calculating Density

  9. Calculating Density • Remember, Density = mass/volume • Mass is determined using a scale • Volume is calculated several different ways

  10. Finding Volume • To find the volume of a liquid, use a graduated cylinder • Make sure to read the bottom of the meniscus

  11. Finding Volume • Length x Width x Height • Volume of a regular object, such as a wooden block

  12. Finding Volume • Water Displacement Method - Read the initial volume of water in a graduated cylinder - Place object into cylinder - Read the final volume of water - Final – Initial = Volume of the object

  13. Density Water Displacement Lab Ms. Ose will assign lab groups

  14. Lab Safety/ Clean Up • No closed toe shoes or aprons are required • If you spill, clean the water with a paper towel • When you finish collecting data, return the lab area as you found it

  15. Density Practice When you finish the lab activity begin working on the Density practice problems. Whatever problems you do not finish will become your homework.

  16. Exit Ticket • Which density problem was the most difficult?
