Students in Maria Nunez’s fourth grade class at Mariposa Elementary are studying matter. Pictured, from left, Joslyn Patterson, Sydney Luppens, Faith White, Taline El-Khoury, Alanna Riverahad were asked to measure the volume and mass of objects. Each station had a different activity exploring matter. For example, at one station, students had to find the volume of an irregular object using water displacement. Students were engaged and learned how to work as a team.
