to hear different ideas, not just those of our friends.

2. Work independently on the pre assessment. Note the fixed error listed on the board. 3. I will let you see your test when we begin our group activity for the day.

Do Now 10/28/14• Take out your work from yesterday.• Person A is manager – make sure to finish by today.• Person B is reader – reads instructions and

summarizes answers.• Person C is document controller- make sure

everyone has the same answer before moving on and be ready to answer my questions.

• Person D is Technician – put away all equipmet and turn in all summary forms with the alien chart at the end.

Do Now 10/29/14

1. Turn in Alien activity within 5 minutes.2. Pick up Element card activity (or take your activity

out)3. Finish this activity by the end of class

1. It is a thinking and explanation activity not a “right answer” kind of activity.

2. A- TechnicianB- ManagerC- Reader/SpokespersonD – Document controller

Do Now: 10/30/14• Draw a Bohr model of nickel.

Complete next

• Turn in element card activity ASAP.• Get 1 grey sheet with instructions and 4 white scratch

sheets of paper to draw Bohr Models on.• This activity is due ½ way through Monday.

1. I WILL check your answers on this one if you need help. There is a right answer!

Do Now 11/3• Take out Bohr Models.• Attach in order AND pattern of periodic table.

• Look for patterns in the electrons in the rows(periods) and columns (groups/families)

Do Now 11/12

1. Turn in pre lab to front counter.2. Take out goggles and something to write

with.

Do Now 11/133 minutes after bell we will check

1. Given the element described by the electron configuration 1s22s22p63s23p64s23d104p3

a. In what period is the element located?b. Name the family to which the element belongs.c. Which group number is the element a part of?d. Is the element a metal, non-metal or metalloid?

Do Now 11/14

1. Last week we investigated coulombic attraction.

a. What is coulombic attraction?b. Does coulombic attraction increase or decrease

as you move down a group? Why?c. Does coulombic attraction increase or decrease

as you move left to right across a period? Why?

Do Now 11/171. Describe and explain the pattern for metal

reactivitya. As you move from bottom to top on the periodic table.b. As you move from right to left on the periodic table.

2. Often non-metals react by gaining extra electrons (trying to get to 8 on the outside shell). Use coulombic attraction to predict which non-metal is the most reactive.

Do Now 11/21

1. Look at your knowledge organizer. Which concept is your strongest? Which is your weakest?

2. Look at your review sheet (or any other hw) to see if there are any questions you think we should go over as a class. Be ready to say the worksheet (color or name) and the problem number.
