# 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 FridayNo 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
