Understanding Atomic Radius: Comparing Sulfur and Oxygen

1. Catalyst 1. Explain why Sulfur has a bigger atomic radius than Oxygen by drawing both Bohr Electron Diagrams. End

2. Lesson 1.8 – Wikispaces Performance Task 1 and Stations Review

3. Today’s Learning Targets • LT 1.2 – I can explain the development of atomic theory incorporating the contributions of Dalton, Thomson, Rutherford, and Bohr. • Review of all Unit 1 Learning Targets

4. Preparing for Assessments • To master the learning targets on the Unit 1 Exam,students will use checklists to make sure they: • Complete Wikispaces Performance Task with uploaded ion creation video. • Create a guideline to tell the atomic theory development story on students’ wikispaces pages as if it were told to an AP student. • Complete the Stations Review in preparation for the quantitative exam. Use the LetsGeddit.com taste tests to guide mastery level assessment.

5. Digital Skills

6. Uploading and Embedding to Wikispaces

7. Upload and Embed • Screencasts available for how to: • Upload Videos to Youtube • Embed Youtube Videos on Wikispaces pages • Insert Images and Files on Wikispaces pages

8. Review Station Protocol

9. Stations Expectations • Stations are sorted according to the learning targets that will be assessed on the Unit 1 Quantitative Exam. • Each station goes over questions similar to exam questions and conclude with a letsgeddit taste test. • You may work in groups, but it is expected that you will be working from bell to bell and keeping the language academic!

10. Taste Tests

11. Taste Tests • At the end of each station, you will log on to your letsgeddit.com accounts and answer the question associated with each station and LT! • Station 1 – LT 1.1 • Station 2 – LT 1.2 • Station 3 – LT 1.3 • Station 4 – LT 1.4 • Station 5 – LT 1.4 • Station 6 – LT 1.5 • Station 7 – LT 1.6 • Station 8 – LT 1.7 and 1.8 • Station 9 – LT 1.7 and 1.8

12. Educanon Support • Any concept students struggle with can be explained by watching the Educanon video lessons for the specific station and lesson. • Educanon Videos Available: • Lesson 1.1 • Lesson 1.2 • Lesson 1.3 • Lesson 1.4 • Lesson 1.5 • Lesson 1.6 • Lesson 1.7

13. Rate Yourself • Rate yourself 1 – 4 on all learning targets • You should study this weekend any LTs that you rated yourself at a level 1 or 2.

14. Review of Performance Task 1: Putting Together The Atomic Theory Totem Pole

15. First Step: Research

16. I. Discoveries of Dalton, Thomson, Rutherford, and Bohr • Research must be done to identify the contributions of Dalton, Thomson, Rutherford, and Bohr to our current model of the atom. • Organize the info using the Wikispaces template.

17. II. Organize and Synthesize • Once all the research is done and the necessary information is gathered, put it together! • Tell a story from the beginning of atomic experiments to the current theory.

18. Second Step: Design

19. I. Drawings of Dalton, Thomson, Rutherford, and Bohr • Draw the models proposed by each scientist in a way that will be easy to reproduce in a model on construction paper. Make sure the Bohr Model looks great! • If you can, make it look shnazzy! • Mr. Astor loves pretty things!

20. II. Record Video of Ion Creation on Mr. Astor’s Computer • Once you’ve determined how to create your atomic model, come to Mr. Astor and record a screencastedvideo explaining the process needed to create an ion from the neutral atom with appropriate commentary. • Astor will save your video for your wikispaces, and you will upload and embed it.

21. Next Step: Build

22. I. Construction of Dalton, Thomson, Rutherford, and Bohr’s Models • Paint/Decorate your totem pole and label your side with chalk! • Put together models using materials available and attaching it to the construction paper. • Make sure your model will fit on your totem pole!

23. II. Take Photos of Finished Models • Once your work is securely attached to the totem poles, take photos of each stage of construction. • Organize pictures to begin your atomic theory story that will be told on wikispaces.

24. Final Step: Capture

25. I. Create Wikispaces Page to Capture All of Your Stellar Creations! • Follow Mr. Astor’s Rubric and his exemplar model to create a Wikispaces page that captures all of the contributions to the atomic model in a story!

26. II. Decorate and Detail • Prepare an explanation for why each model improves on the one below it and describe what experimental evidence lead to this discovery. • Your story should be created to re-teach my AP Chemistry students this concept from last year!

27. Work Time • Let’s Get to Work! • Get Cooking!

29. Closing Time • Finish all Performance Task, stations work, and checklist activities by exam time for best results! • UNIT 1 Quantitative EXAM Wed - Friday!
