June 10th marked the first week of the new Summer STEM (Science, Technology, Engineering, and Mathematics) Program at Washington Elementary School in Santa Ana. The program gives students a look into the work of researchers and professionals in STEM fields. Each week of the 5-week program, a different professional introduces their work through an interactive presentation and hands-on activities. The fields represented this year include ecology and evolutionary biology, computer programming, electrical engineering, renewable energy systems, environmental chemistry, and aerospace engineering. During the first week, students observed marine invertebrates in a touch tank, learned how to measure biodiversity, and mapped out a food web.
