Welcome to Ms. Bennett's
8th Grade Science Class
If you are absent please read through the web page so you know the learning targets and tasks for the day. All the assignments are stored in the back file cabinet to pick up when you return. If you need extra time for investigations or reading please come before school (8:10-8:25) or after school (3:00-3:30). Readings can be worked on during lunch as well in the library using the reference science book there.
Do you learn fast? Extending your learning is important. Look for weekly extensions to take your knowledge deeper! Extensions are located in the front of our shared file cabinet #2. Talk to Ms. Bennett for more information.
Practice with mass, volume, surface area, and density on the computer at school or home!! Link to diagnoser.com using the id and password Ms. Bennett passed out on Friday, October 2. Please keep your id and password in your planner.
Please bring your composition book for your lab learning log everyday! Remember to buy lots of glue sticks. You will need them! Questions? Email me at jbennett@bham.wednet.edu
Learning targets and focus questions from today (or the future) going backwards in time!
