Today in Science the concepts of diffusion and osmosis were introduced.  These concepts often require time for students to fully understand. I suggested to all students that they spend some time reviewing the concepts tonight.  I have included a couple of videos that student might want to review. Students are not required to know everything covered in these videos they are meant to help students grasp the big ideas and some of the terminology such as: diffusion. osmosis. and semipermeable membrane.
