4. Warm – Up: PRIDE Pact
Think about yesterdays milk lab and discuss the following questions with your group:
How did you resolve any issues?
What was it like to work together?
Did you feel safe during the activity?
How could this lab be improved?
Respect one another, not talking when others talk, coming to class prepared, collaboration – active roles in the lab, lab behavior. How should we treat each other when working in groups?
* Not enough to say members will respect each other… need to say how by keeping hands to yourself, etc.

7. Agenda: Warm – Up - PRIDE Pact Administrivia Finish Milk Lab Questions
Exit Ticket

8. PRIDE Pacts Lets create our classes PRIDE Pact
Other Questions to consider:
How could technology be used appropriately during this activity?
What kind of support do you want from your teacher?
What kind of support do you want from your lab mates?

9. Classroom Expectations
You will be seated at your desk and working on the warm-up when the bell rings
There will be random warm-up quizzes
ALWAYS be prepared to take notes and participate in labs
Students must ask for permission to leave the classroom
And use an agenda book even if its for water

10. Classroom Expectations
You are expected to follow the Howard County Code of Contact
No Cell Phones or electronics (unless otherwise noted) during class. Devices must be silent and out of sight. (Not left on vibrate)
No hats
NO FOOD

11. Materials You are expected to come prepared to class Pen/Pencil
Notebook (or Folder) – your personal preference
Calculator (TI-30X recommended, NOT required)
Textbook will be passed out during the second week of school

12. Grades
Grades will be posted on Aspen. Grades will be rounded based on the county requirement. A grade of an 89.49% is a B.

13. Late Work
Accepted the next day at the beginning of class for half-credit
Any work handed in after one day will not be accepted and will be given zero credit

14. Absence Your responsible for making up work when absent
For excused absences you will be given the same number of days that you missed to make up the work
Unexcused absences will result in not being allowed to make up missing work
Students have one week to make up missed exams and labs
Check the make up folder, ask your peers, then ask me!

15. Lab Safety Lab safety is a priority in the chemistry classroom
All students are required to sign the safety contract
You MUST wear goggles and closed-toe shoes to participate in lab.
Failing to follow rules will cause removal from the lab and a zero on the assignment!

16. Extra Help Available before and after school
Make prior arrangements with me
You can always me questions at night and I will respond back

17. PBIS System

18. Tardy Policy

19. Redo Policy
Students will be afforded redo opportunities on assignments/assessments based upon the overall class performance on those assignments/assessments, but individual students may discuss the possibility of a redo with his/her teacher.
DO NOT ask to redo a test while taking a test

20. A word about academic integrity … Don’t Cheat, Don’t Cheat, Don’t Cheat

21. A Note About STEM Fair
Data collection should have been completed over the summer
We will work on data and statistical analysis in class during week 7 of school
If you transferred into Howard or did not begin a project in Bio GT, see me ASAP

22. STEM Fair Timeline
Data Collection and Analysis       October 10th Conclusion             TBA
Abstract TBA
In- Class Presentations                         TBA Howard High School STEM Fair             TBA Howard County STEM Fair                    TBA

23. Questions

24. What is scientific notation?
Let’s Think…
What is scientific notation?

25. Discussion
So what?

26. Collaborate
In groups, brainstorm 3 examples of things that scientists/ engineers could study that would be large enough or small enough for scientific notation to be used to describe them

27. Activity
Each group has an envelope containing numbers in scientific notation and standard notation.
Objective: Put the numbers in order from smallest to largest on your desk.

28. Scientific Notation
A way to write numbers that are too big or too small to conveniently write in decimal notation
Standard scientific notation format
6.02 x 1023
Notice there is only one number before the decimal

29. Standard Notation to Scientific Notation
Standard Notation – numbers that are in decimal form
When given a number in standard notation move the decimal to the left or right until there is only one number before the decimal
The number of spaces moved to the left or right becomes the exponent
If sign on the exponent is
Positive – moved the decimal to the left
Negative – moved the decimal to the right

30. Standard Notation to Scientific Notation cont.
Examples
(Standard Notation)
Move the decimal to the left, exponent is positive
4.89 x 108 (Scientific Notation)
(Standard Notation)
Move the decimal to the right, exponent is negative
1.23 x 104

31. Scientific Notation to Standard Notation
Start with number in scientific notation
Look at the sign on the exponent
If positive, move the decimal to the right
If negative, move the decimal to the left
Use the exponent to tell you how many places to the move the decimal point

32. Scientific Notation to Standard Notation cont.
Examples
3.47 x 105 (Scientific Notation)
Exponent is positive, move to the right
(Standard Notation)
7.82 x 10-4 (Scientific Notation)
Exponent is negative, move to the left
(Standard Notation)

33. Multiplying/Dividing in Scientific Notation
Multiply or divide the numbers first
(don’t include x 10exp)
When multiplying, add the exponents together
When dividing, subtract the exponents
Make sure there is only one number before the decimal place in scientific notation. You may have to move the decimal so there is only one

34. Multiplying/Dividing Scientific Notation cont.
Examples
1. (2.0 x 105)(7.0 x104)=
Ans: 1.40 x 1010
2. (15.0 x 107) / (3.0 x 109)=
Ans: 5.0 x 10-2

35. Scientific Notation Practice
Complete the practice at your desk. Whatever you do not finish will become your homework.

36. Finish Milk Lab Questions

37. Exit Ticket
