This week in class we reviewed our chapter two test on chemical reactions, reviewed our International Boiling point project and some classes even participated in a video conference with a school in pennsylvania.
Today we did a short review on surface tension (we will be reviewing material covered in 6th and 7th grade as we get closer to the NJASK test). We watched a youtube video of a water droplet bouncing in slow motion. The video can be found at
