Toilet Paper Lab Questions

Answer the following questions for your toilet paper lab.  Make sure you have the correct average pennies held for each brand of toilet paper (and not the total pennies).

Conclusion

5. Write a conclusion based on the data gathered from the experiment. Was your hypothesis correct? Why or why not do you think your hypothesis was supported?

6. List possible sources of error in this experiment. What ways can the procedure be improved to give more reliable data? Note: During any experiment, it is good practice to record if and where any errors or inconsistencies may have occurred and whether they are equipment-related.

7. Explain in your own words the procedure to test the toilet paper.  Make sure to clearly describe each step and the purpose of the step.

Snack Lab Questions

If you did not have a chance to finish the questions for the snack lab, here they are.

Questions:

1. Which snack was more cost effective: unshelled or shelled?  Is this what you expected, why or why not?  Use your prior experience shopping to explain.

2. What could be sources of error in your laboratory procedure? What could you do to be more careful and accurate in the laboratory?

4. How will you use this experience to be a better shopper when you visit the grocery store?

Binder Organization

Please organize your dividers in your binder in this order:

1. Notes
2. Classwork

Chemistry Syllabus 2014-2015

This is the syllabus for this school year.

Welcome to Ms. Cotta’s Chemistry Class!

Room: S 303                Periods: 1, 2, 3, 4 & 6              E-mail: julianne.cotta@lausd.net

Website: www.mscotta.blogspot.com

This school year we will study many aspects of chemistry including properties of matter, periodic table, atomic structure, atomic bonding, radioactivity, and organic chemistry.  It is essential in order to be successful at chemistry to have a strong algebra foundation.  This class will also require strong reading and thinking skills. It is essential that the student keeps up with the work assigned and studies regularly.  There will be a midterm and a final that will require students to review and prepare in order to receive a passing grade in the class.  All work and upcoming due dates are posted on Ms. Cotta’s website on a regular basis.  Also feel free to contact with questions via e-mail or calling the main office to schedule a parent conference.

Required Materials (brought to class EVERY DAY!):

1) Binder with five (5) dividers                                               3) Loose lined paper (not in a spiral notebook)

2) Composition Book                                                  4) Pencils and pens (blue or black ink only)

Grading Policy:

A = 100-90%               B = 89=80%    C = 79-70%     D = 69-60%     F=less than 60%

Assignments are given the following percentages in your final grade:

Tests: 45%       Labs: 20%                   Homework: 15%         Class Assignments: 10%          Projects: 10%

Class Rules:

1) Respect others & yourself

2) Be on time, prepared & ready to learn

3) No electronic devices used in the classroom, make sure cell phone are off

Students that continue to leave cell phones or other devices out will be confiscated and returned after the class period. If the student continues to have electronic materials during classtime; the device will be collected and sent to the SOTA office for the parent to pick up.

4) Take care of the classroom and all supplies and materials; no gum, food or drink

Students will not write on or destroy any materials in the classroom.  If any material is found tagged or defaced, the student will be expected to help clean and beautify the defaced area.  Groups will be held responsible for their table and area around it, all members will be held accountable for cleanup.

5) Have a positive attitude & do your best

6) Always reuse, reduce & recycle, recycling bins are next to trash can

Absences:

If a student is absent, it is their responsibility to make up the work missed.  Student can see the teacher before school, after school or lunch to pick up missing work.  If class notes are missed, the student is responsible for asking another member of their class for missing notes. Any missed test will be made up the following class. Homework and assignments can be found on Ms. Cotta’s website, so check it often to make sure you are up to date or have any questions.

Homework:

Homework will be assigned every Monday, Wednesday and Friday.  Late homework or other assignments may be turned up to two days late.  This means if that the work is due on Monday, it may be turned in Wednesday but not Friday.  The late work will be deducted 20% for being late.  After two classes, no late work will be accepted.

Tests:

Students will be given a test at the conclusion of each chapter and will be notified with at least two days notice of upcoming test dates.  Study guides will be posted on Ms. Cotta’s website to help review topics that will be found on the test.  It is also essential that the students’ review all work assigned including homework, labs and classwork/class notes.

Laboratories:

Laboratory activities are an essential part of the chemistry classroom.  In order to create a safe working environment, all students must follow directions, keep work area clean and be efficient and safe when working.  All students will need to sign a safety contract before participating in laboratory activities.  Any student that is creating an unsafe environment by not following directions or “goofing off” will not be allowed to participate in that laboratory and will receive a zero on that assignment.  The student will also receive an alternate assignment that will need to be completed.

Composition book and classwork:

All warm up assignments, exit questions and laboratories will be written in the students’ composition books.  Composition books will be kept neat and orderly with legible handwriting.  Every Friday where a test has been given, composition books will be collected and graded.  For example, if a test is on Tuesday, students can expect to turn in their composition book three days later on Friday.  Other classwork such as reading assignments will be given on a regular basis and will need to be turned in separate from the composition book.

Tutoring/extra help:

Students can visit Ms. Cotta for questions or help before or after school or lunch.  Ms. Cotta will also hold after school tutoring if students need additional assistance to keep on track.  All students are welcome to attend tutoring sessions, but some students will be required based on their class performance.  Parents will always receive notices home if the student is required to attend tutoring after school with dates and times noted on the paper.

Communication with parents:

I will call on a regular basis if your student is missing work or has behavior issues in class.  Feel free to contact me or e-mail me at the address on the other side of this paper.  If you have concerns, please schedule a parent conference.  Please make sure that there are correct phone numbers on file, so we may contact you.

I look forward to working with the students and the parents this year to make it a highly successful year. Please do not hesitate to contact me with any concerns or questions.

Thank you for your help and support.

Ms. Cotta
