Lecciones de investigación científica de séptimo grado

7th Grade Science Class Outline

This is a yearlong course that students can log in for the weeks that interest them. I teach with a presentation and align hands-on activities to the standards. I also stop periodically to check for student understanding. We use the whiteboard, chat box, and sometimes breakout rooms. I will cover all the National Science Standards required for grade 7 science. 

Here is the schedule: Each week is a stand-alone subject within the standards of science.
