Welcome to Science! I am the 7th grade science teacher, Mr. Ali, and it is a pleasure to have you all as part of the MS 890 community. Throughout this year we will be exploring various angles of the scientific world ranging from atoms to technological design. As a class we will explore the world while building a community in the classroom! On this page, you will find information about assignments, upcoming quizzes or exams, review materials, and interesting science articles. I am looking forward to an exciting year in science class! If you have any questions, feel free to contact me at Mali17@schools.nyc.gov
Every month I will post an interesting science article on this website. If students read the article and write a reflection on it, they will receive extra credit towards the classwork grade. The reflection must be at least one paragraph and address the following questions: 1. Explain what you find interesting about this article and why. 2. How does this article relate to your life? 3. What did you learn after reading this article?
This is a great opportunity for students to hone in on their reading and writing skills, and ultimately prepare to read higher level scientific articles in high school and college!
