Here are two activities for students exploring the concepts of sinking and floating! In activity one, students test different objects to determine whether the objects sink or float. I included differentiated worksheets to help students record their findings. In activity two, students perform an experiment where they determine how many objects it will take to make a floating container sink! Any extra materials that you may need for these experiments, I listed in this product. I also included some science word cards. My class and I enjoyed these activities and I hope yours does too!
