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!

Science Fair Project Timeline: April 8th-12th: students finalize their introduction, hypothesis, procedures, materials, and plan to collect data for their project. April 19th -May 3rd: conduct the experiment and record data and observations May 6th-10th: complete data analysis and conclusions May 20th -24th: class presentations May 29th: MS890 Science Fair June 6th: District 22 Science Expo June 13th: District 22 Middle School Science Fair
Science Project Outline: Part 1: -Question: What are you testing? -Introduction: Explain the science concepts related to your topic. Part 2: -Hypothesis: Predict the outcome of your experiment based on your knowledge and research. -Materials and Procedures: Thoroughly explain the materials and procedures you used to conduct your experiment. Add pictures and explanations to aid in understanding. Part 3: -Data and Observations: Record your findings in tables, charts, and/or graphs. -Analysis and Conclusions: analyze your data and connect your findings to your question. How does this support or refute your hypothesis? How is this relevant in your life/community/environment
