Start the following in class:

1.  The required journal focus question  J34 for today is:

What evidence convinced Ernest Rutherford that most of an atom is empty space with each atom having an extremely small, dense, positively charged nucleus?

2. Doing ChemThink interactives are part of the core experiences for all chemistry students.

  • Log onto the ChemThink web site http://simbucket.com/chemthinkserver/chemthink/  to do the tutorial and question set on Atomic Structure.
  • Choose menu selections:  The Atom > Atomic Structure Tutorial.  [If you are logged onto the ChemThink web site, you do this by clicking on the green triangle in the white circle to the right of the displayed module’s name. If you were taken directly to a web page with an orange Tutorial button and a blue Problem Set button, click on the orange Tutorial button.]
  • If you do not have a copy of the worksheet that goes with this module, click on the provided link to the ChemThink worksheet for this module or, if that doesn’t work, locate it in the Student Resources > Handouts > ChemThink Formative Assessment Note Sheets folder. Download the worksheet, and print off a copy.
  • Place your hand in number and name in ink in the upper right corner of the worksheet.
  • Now work your way through the online tutorial.  You will have to answer each problem correctly to advance to the following page. FYI: When there are check boxes given before possible correct responses in either the tutorial or the problem set, more than one response may be correct, so carefully consider each response before submitting your answers.
  • Record a response to each question asked on the worksheet.
  • Then choose the menu selections:  The Atom > Atomic Structure  Question Set to formatively assess the understanding that you have built up by doing the Tutorial.  Try to do each problem in the Problem Set correctly during your first attempt at working  your way through the problem set.  If you get a problem wrong, focus on understanding why each problem in the question set is answered in the way that it is.   Your goal is eventually to have a deep enough understanding to score a 10 out of 10. If you did not attain that level of understanding the first time through, review some more, and do the problem set again until you have mastered the content with a 10 out of 10 score.
  • Place the worksheet in the Notes section of your 3 ring binder and bring it to class.

3. Do the worksheet entitled Average Atomic Mass From Percent Abundance . Answer the questions in full sentences and show your work for the each problem.

Recommended for those who have time left in their 45 minute study period, but not required of all:

1.  Do the worksheet entitled Rutherford’s Gold Foil Experiment. Answer the questions in full sentences.

2. Check out the student made Quizlet for chapter 4 at https://quizlet.com/162992116/honors-chem-ch-4-flash-cards/ .  Do all the definitions reflect a thorough and correct understanding?

3. Open the Unit Learning Objectives for Cornell Notes document, Press and hold the CTRL key while typing F to bring up a search (find) box.  Type in Chapter 4 in the search box and then move your cursor into the text area to the right and click there to see the first page of objectives. Consider whether you can do chapter 4 learning objectives 10 through 15, and study them as you proceed through the chapter with the aim of being able to demonstrate your understanding and ability to apply the learnings.  Study and take study notes as seems appropriate.
