These Bellringer slides are for a semester of 7th Grade Science. They cover: start of school procedures, safe lab practices and equipment use, energy transformation, cells, body systems, and organic molecules. TEKS (Texas Essential Knowledge and Skills) pertaining to each question or activity are included, as are answers on a Teacher slide after each question. These slide are editable (if not let me know and I will fix them!!!) The warm ups should only take a few minutes to complete at the start of class. They are usually independent practice or review of applicable sixth grade TEKS, but some are table activities. These questions can be answered on a piece of notebook paper set up Monday-Friday by students. You can make an answer document, but if you are like me, you don't want to use the copies you have for a warm up. Enjoy.
