Fifth grade students, Heather Heath, Tuan Tran, Levi Gonzalez, and Sophia Lopez in Carla Bargeron’s Science resource class at Mariposa Elementary recently completed an exciting science unit.  Students first learned about landforms and volcanoes and then worked in teams to design and construct paper mache’ volcanos.  Students also learned about the steps in the scientific process and physical and chemical changes in matter.  Mrs. Sandra Bushby and the fifth grade students were thrilled as they conducted “explosive” experiments with their hand-made volcanoes and gooey “lava”. Aka jello chemical changes can be fun!
