Category Archives: Density

Friday, 3/17/17- A Day

Core Ideas:

  • Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.
  • Each pure substance has characteristic physical properties (for any bulk quantity under given conditions) that can be used to identify it.

Learning Activities:

Periods 3, 6, and 7

  1. Do Now– Copy down today’s homework assignment in your planner.
  2. Science Friday– No Strain, No Gain
  3. Gallery Walk- Hang your model on one of the upper cabinet doors. Walk around the room, studying all the models. Notice all the different ways other groups modeled the phenomenon. With your post-it note, write feedback about complements about ideas a group had (I value…) or questions that you had about their model (I wonder…).
  4. Develop a Group Consensus Explanation Discussion– Put chairs in circle and review discussion norms. What did you notice that was common in every model? What did you notice that some groups had in their models? Did you notice that one model had an idea that was unique? Use observations from the models to come up with a group consensus that explains how the person is able to float on top of the water and couldn’t sink in the Dead Sea and how density determines whether matter floats or sinks.

Periods 2 and 4

  1. Do Now– Copy down today’s homework assignment in your planner. Get out your science notebook and open to pages 52-53.
  2. Science Friday– No Strain, No Gain
  3. Anchoring Phenomenon/Model- Complete the final model about how you think the person is able to float on top of the water and couldn’t sink in the Dead Sea. How does density determine whether matter floats or sinks?
  4. Density Informative/Explanatory Writing- DRAFT-Use the pre-writing assignment from Mrs. Fraczek’s Language Arts class and the Google Form assigned in Google Classroom to write a DRAFT of a paper explaining how density determines whether matter sinks or floats. Use complete sentences and type in the light gray boxes.

Homework:

Density Informative/Explanatory Writing Draft (Google Doc) is due Monday, 3/19

Thursday, 3/16/17- B-Day

Learning Activities:

Periods 3, 6, and 7

  1. Do Now– Copy down today’s homework assignment in your planner. Get out your science notebook and open to pages 52-53. Talk with your cooperative table group about how we can make sure everyone has a chance to participate in a class discussion. What might keep someone from participating?
  2. Physically rehearse class procedure of putting chairs in circle. Establish discussion norms.
  3. Anchoring Phenomenon/Model- Complete the final model about how you think the person is able to float on top of the water and couldn’t sink in the Dead Sea. How does density determine whether matter floats or sinks? OR
  4. Density Informative/Explanatory Writing– PRE-WRITING- Complete the paint chip organizer from Mrs. Fraczek’s Language Arts class

  • Each pure substance has characteristic physical properties (for any bulk quantity under given conditions) that can be used to identify it.

Learning Activities:

  1. Do Now– Get out your science notebook and open to pages 52-53. Read what you wrote for the Sinking and Floating Activity. Be prepared to share with the class what your group wrote for each column.
  2. Driving Question Summary Table– Complete the Summary Table on pages 52-53 for the Sinking and Floating Activities on pages 62-65.
  3. Anchoring Phenomenon/Model- Watch the person floating on the Dead Sea video segment again. Create a final model about how you think the person is able to float on top of the water instead of swimming in the Dead Sea. (Cooperative table group)

  3. Demonstration & Model (except Period 3)– Do all liquids have the same density? Record your demonstration observations of the candles floating on two different liquids and the density column on page 65. (Period 4 only) Review Questions 3 & 5 and trim& tape them as a flip page to p.65. Answer Question 6 about water alcohol and oil on the molecular level. Trim and tape the handout to page 64.
