An Introduction...
First, to give you a little background about myself… I graduated from DSA as a seven year Creative Writing major. I was an instrumental music minor (I play the flute) but have been involved with all the art forms. I then attended the University of Denver and received two degrees: Environmental Science (the integration of life, earth, and physical sciences) and Conservation Biology. I worked at the Denver Zoo after graduation as an instructor of 4 and 5 year-olds and discovered that I loved teaching science. I then obtained my teaching license from the University of Colorado at Denver while working as a substitute teacher at DSA. This is my first year with my own classroom and I am very excited to have the privilege of teaching at DSA!
In my classroom we explore science with hands-on experiments and demonstrations. I focus on critical thinking and problem-solving skills while following the physical science fundamental units as approved by the District:
Physical Science Units
Unit 1—Foundations
Scientists believe that all events can be explained in terms of the interactions between objects. Scientists study interactions through observations and experimentation to determine the properties of objects and the nature of the interactions.
Unit 2—Interactions and Energy
Scientists can describe, analyze, and explain interactions by considering the energy transferred between the objects.
Unit 3—Interactions and Forces
Scientists can describe, analyze, and explain interactions by considering the forces between objects such as the gravitational forces between Earth and other objects.
Unit 4—Interactions and Conservation
Despite the changes that often occur during interactions, some things remain the same. During interactions in closed systems the total mass and energy stay the same.
Unit 5—Materials and Other Interactions
Scientists classify materials by their characteristic properties and interactions. When two materials interact and a new material is formed it is called a chemical interaction; otherwise, it is a physical interaction.
Unit 6—Physical Interactions and Phases
Scientists use models to help them think about things at scales too small or large to observe directly or with tools that extend the senses. The Small Particle Theory is a powerful model for thinking about matter and how it interacts with other matter.
Unit 7—Chemical Interactions
Scientists use the Small Particle Theory to understand what is happening to the mass and energy of a chemical system during a chemical reaction.
Class Syllabus
Student Expectations
My classroom is a safe place for all students. I hold high expectations for all students to be respectful and considerate of others and others’ property, always acting with integrity. Please remember to listen quietly to instructions and the opinions of fellow classmates. I will conduct my class according to Denver School of the Arts’ Classroom Management Ladder. In addition, all students’ work must be their own. Plagiarism will result in a 0 that can not be made up.
Please bring to class everyday:
~ Paper and writing utensils
~ Science notebook
~ Text book (InterActions in Physical Science, 2006)
~ Activity booklet
~ Your creativity!
Please do not bring to class:
~ Cell phones and/or pagers
~ I-pods, walkmans, etc.—please, no earphones in ears during class
~ Recording devices—unless given to me before class
Grading
I will grade students according to the following: (A rubric will accompany each assignment if necessary.)
1. Participation/Attendance 10% of final grade
2. Science Journaling Notebook 10% of final grade
3. Lab Reports 20% of final grade
4. Cumulative Unit Projects 20%
5. Class work/Homework 20% of final grade
6. Exams 20% of final grade
A 100-90%
B 89-80%
C 79-70%
D 69-60%
F 59-0%
Unexcused/Late Work Policy
All students will be expected to complete and return all assignments on time. One class period late will result in a 25% reduction in points. Two class periods late will result in a 50% reduction in points. If the assignment is more than 2 class periods late, it will not be accepted. If the student has a legitimate reason for the assignment being late such as illness, family emergency or in-school performance, please let me know before the due date and adjustments will be made. I do not assign or accept extra credit assignments. However, if a student wishes to improve their science notebook or lab report grades they may correct and re-submit their assignment no later than three days after it was returned for a higher grade. Please note that points deducted for a late assignment can not be made up.
Attendance/Tardy Policy
I expected students to be present and punctual to class. Denver School of the Arts’ attendance/tardy policy will be up-held. If your student will be absent they need to be excused through the main office and have two days to complete missed assignments. If a student is late to class it will be recorded by myself and the main office. Students need to bring a note from the main office to class if they are late. A tardy will result in the student not receiving their full participation/attendance points for that day. If a student is absent or late, it is their responsibility to collect work they missed.
Safety
For safety’s sake, no food or drinks are allowed in my class because chemicals may be present. Water bottles are acceptable on days where we are not conducting a lab. If labs are being conducted, students must follow all safety instructions given.
Contact Information
I am committed to helping students succeeded-- so please let me know if I can help in any way. I am available during access, lunch, my free period, and after school until 3:15. If you plan to come after school, please let me know ahead of time. My e-mail is katrina_marzetta@dpsk12.org, which is the best way to contact me. You may also reach the main office at 720-424-1700 to be transferred to my room (B112).
Formal Lab Write-Up Rubric(Please use this format for all formal lab write-ups until otherwise notified.)
The following is the different sections required for a formal lab writ-up. Also, included are the expectations for each section and the amount of points it is worth. Please have all lab write-ups typed. This format is very similar to what you would encounter in higher academia. If you have any problems or concern please see me before each lab is due—I will be more than happy to help. Have fun being scientist!
