Mrs. Spong came to visit us with a very cool science activity. We have been learning about solids and liquids during science. She brought in an activity that tied in perfectly with out unit. Each student had the opportunity to create their own "wave machines" using colored water and mineral oil. Mrs. Spong taught us all about density! The kids first compared different solid blocks and sorted them by weight. After this we made our "wave machines". It was a lot of fun. Thank you so much Mrs. Spong!!!
