Dear students and families,
Hello and welcome to Environmental Science!This is a two-semester class in which we will investigate plant science, weather science, ecology, and alternative energy.Each class session will include a discussion of new material, review of at-home assignments. Independent work will comprise about 40% of the workload and will include completion of lab reports, reading assignments with comprehension questions, reflections on in-class notes, independent research projects, and take-home tests.
You are required to bring the following to class each day we meet:
- 2.Binder (1 1/2- 2 inch), with assignment sheet and two section dividers: “Notes”, “Returned Work”
- 3.Binder Paper
- 4.Pen and Pencil
Phone Use policy: I encourage you to use your phone for class related research and notes. If you are using it for other things, your grade will suffer. It's a matter of trust since it’s hard for me to tell what you are doing on your phone.
Homework: I hope that you do it all yourself, but if I suspect plagiarism, meaning any sort of copying or cutting and pasting, there will be serious consequences. Plagiarism is a serious offense and will result in a call home to parents and possible removal from the class.
In order have a classroom community in which everybody feels respected, safe, and enthusiastic about learning, each student must be mature, responsible and respectful.Please refer to the Orchard View Behavior Guidelines for specific rules.We will discuss as a class laboratory safety procedures.
Students’ grades will be based on completion and quality of assigned work, attendance, and participation in class activities and discussions according to the approximate percentages below:
Independent Projects/Lab Reports/ In-Class Activities 20%
Attendance/ Participation 20%
These are write-ups on in-class laboratory projects.We will discuss the format in class.
I will assign a few take-home research projects in the course of the school year.There will also be a few group presentation projects.Late projects will be marked down 10% (one whole letter grade) for every day they are late.
Generally, I will give a test at the end of every two chapters which will include both multiple choice and short-answer sections.Some short quizzes will be given in the interludes.I will announce the date of the tests at least one week in advance.I will announce quizzes at least two days in advance.There will be no pop quizzes.
I will give homework assignments at every class meeting.These will consist of reading assignments with comprehension questions, completion of lab reports from in-class labs, and online activities.Assignments will be due at the beginning of the following class meeting.Late assignments will receive half credit.If you are absent, you will be allowed to have the same amount of time everyone else had to complete the assignment.
I require students to take notes from the lectures. These notes will be checked and graded the following class.Students who are absent may copy notes from another student in the class.
Attendance is crucial to your success in this class.It is very difficult to catch-up if you fall behind.You will receive attendance credit for every day that you are present, on time, and ready to work.Your participation grade will be based on your participation in class discussions, both as a listener and a speaker, your ability to cooperate and work well in small groups, and your class behavior.
I am usually available briefly before or after class for students needing assistance with an assignment.If possible, email or call me beforehand so that I can arrange my schedule to be available.
