1. P RACTICING NGSS Sara Dozier Integrated Middle School Science Partnership

2. Questions and Concerns Find your half-sheet from the morning session – “IMSS Summer Institute Formative Assessment” On the “Afternoon” side of the sheet, please answer the first question only!

3. NGSS Learn Together Time This week: One hour per day Mon-Th Identify the shifts that the NGSS require Emphasize 2 practices: – Constructing Explanations – Arguing from Evidence “What should I be doing this year with NGSS?”

4. Monday Outcomes Experience the Science and Engineering Practices Understand the rationale for the Science and Engineering Practices in the NGSS

5. Moldy Sandwich One Monday, I didn’t feel like eating my sandwich at lunch so I put it in my locker in a sealed zipper bag. I forgot about it until the next week. When I found the sandwich, it was all moldy and gross. There was so much mold on the bread! http://2.bp.blogspot.com/- 3QbTA2OKq7I/T3EgiOPNMzI/AAAAAAAAAE8/tZmkb- Et76s/s1600/resblues3.jpg

6. Moldy Sandwich If nothing could go in or out of the sealed bag, the weight of my sandwich bag and its contents after a week in the locker is: more than when I put it in the locker the same as when I put it in my locker less than when I put it in the locker Explain your answer to a partner. http://2.bp.blogspot.com/- 3QbTA2OKq7I/T3EgiOPNMzI/AAAAAAAAAE8/tZmkb- Et76s/s1600/resblues3.jpg

7. Watch Demonstration Wearing your “student hat,” what investigable* questions do you have about what you just saw? Could we relate this activity to the question from the warm up? How does it relate to the moldy sandwich? * Investigable Questions are: feasible interesting, challenging, stimulating, motivating to students practical in terms of difficulty, time, and resources not yet answered by students

8. Lab Activity 1.Add vinegar to corner of bag without the baking soda. Do not mix the vinegar with the baking soda. 2.Press out all of the air from your bag without mixing the vinegar and baking soda. SEAL the bag completely. Do not mix the vinegar with the baking soda. 3.Record the mass of your bag with baking soda and vinegar kept separate. Do not mix the vinegar with the baking soda. 4.Combine the vinegar and baking soda. Okay, you can mix them now. 5.Record your observations. 6.Record the mass of the bag after the reaction has stopped. (How will you know?) 7.Open the bag and press out all of the gas. 8.Record the mass of the bag again.

9. Share Your Results On the chart paper, please have one team member record the three data points from your group’s experiment.

10. What Happened? In your group, construct an explanation about what happened. Include: – Claim (What happened in your system?) – Evidence (not inference!) that supports your claim – Reasoning (how does your evidence support your claim?) Be prepared to share your explanation

11. Sharing Ideas Use the handout “Language Structures for Scientific Argument” One team shares their explanation. Other groups respond and share ideas. Consensus explanation or forward plan developed.

12. What Do Scientists Actually DO? During an average work day, what do most scientists spend their time doing? – Does it change during their career? – What skills does a scientist need to be able to complete these tasks? Think for a moment about how your students would answer these questions. Discuss with a partner and be ready to share.

13. What Do Scientists Actually DO?

14. 8 Science and Engineering Practices Three Dimensions 44 Disciplinary Core Ideas Physical Sciences Life Sciences Earth and Space Sciences Engineering, Technology, and Applications of Science 7 Crosscutting Concepts Next Generation S cience Standards

15. Developing and Using Models Constructing Explanations and Designing Solutions Analyzing and Interpreting Data Engaging in Argument from Evidence Obtaining, Evaluating, and Communicating Information Using Mathematics and Computational Thinking Asking Questions and Defining Problems Planning and Carrying Out Investigations Practices

16. Performance Expectations The “Standards” are the Performance Expectations (PEs) and the contents of the Foundation Boxes Next Generation S cience Standards

17. Practices Look at the 3 Dimensions of NGSS handout (color) in your binder. Which S&E Practices did we engage in? Which S&E Practices were emphasized? If you were to change this activity to emphasize a different S&E Practice, which practice would it be and how would you change the activity?

18. Practices Engaging in the Practices: – Makes science knowledge meaningful – Embeds the DCIs and Crosscutters into students’ worldview – Differentiates process vs. products – Piques curiosity – Motivates further study – Demonstrates the creative aspects of science A Framework for K-12 Science Education, NRC

19. Practices What about the scientific method? – The Scientific Method skills are still here! A Framework for K-12 Science Education, NRC

20. Practices The NGSS reduce focus on experimentation as the work of scientists. A Framework for K-12 Science Education, NRC

21. Practices The NGSS emphasize modeling, critique and communication as part of the method of doing science. Peter Higgs and Francois Englert

22. Activity for Activity’s Sake The NGSS are not a pendulum swing to the “other extreme” The goal of the NGSS is to marry “content” with the process of “students figuring it out” NOT to leave out the content ideas.

23. Possible Content Connections MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

24. Possible Content Connections MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

25. Possible Content Connections MS-ESS3-5. Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

26. Connections How could you connect this activity to your classroom?

27. Thank You Please finish today’s exit slip – On “AFTERNOON” side, answer second question and add any comments Sign out and hand in exit slip and name tag at table in hallway See you tomorrow morning for breakfast!
