The Water Wheel Published by Coachella Valley Water District to develop responsible water users for tomorrow. Spring 2016 Excellence in water science awards presented to valley students This year, educators again had the privilege of judging and selecting students whose projects demonstrated excellence in water science. Generally, there is no shortage of projects that include some aspect of water. We truly enjoy the diversity of projects that we see annually and this year was no exception. Part of the focus in judging this year was to see if the students had truly followed the scientific process by stating a specific problem and hypothesis with one variable that changed while keeping all others constant, to observe changes in their outcomes. We are pleased to share with you the winners of CVWD’s Excellence in Water Science awards. Private Schools Danna Ruppel, 7 grade at Desert Christian Academy. Project: Cups to Clouds. Danna put together a solid, straight forward science experiment that asks the question, “Do all liquids evaporate at the same rate?” Her hypothesis was that liquids with additives would evaporate at different rates. To test the hypothesis, Danna poured equal portions of different liquids: Monster Energy Drink, apple juice, soda, green tea and water into uniform sets of cups. The cups were placed outside and measurements were recorded daily. Data confirmed Dana’s hypotheses. Liquids containing sugars and sodium evaporated at different rates than water. Science Teacher: Vivy Mathews. th Coachella Valley Unified School District Esperanza Figueroa, 5 grade at Westside Elementary School. Project: Which freezes faster, cold, hot or warm water? Esperanza was testing a theory she read about called the “Mpemba Effect” where a Tanzanian student discovered that, when making ice cream, hot water froze more quickly than cold water. Although she was aware of the Mpemba Effect, Esperanza believed that cold water would freeze more quickly than hot water and stated that in her hypothesis. After several tests using cold, warm and hot water, her hypothesis was not proved but rather the opposite, that hot water freezes faster than cold water. Science Teacher: Vidal Tafoya. th Desert Sands Unified School District Bryan Chang, 6th grade at Sacred Heart Catholic School. Project: Can the Moringa Oleifera Seed Save the Salton Sea? Bryan investigated the Moringa Oleifera seed’s ability to reduce hydrogen sulfide (the rotten egg smell) and desalinate Salton Sea water. He created a filter medium by removing the seed’s husk and pulverizing the seeds. After running several tests with different amounts of pulverized seeds, and checking for hydrogen sulfide and salinity levels, Bryan was able to demonstrate that the Moringa Oleifera seeds were an effective filter. The project was thorough, detailed and complete with extensive, valid research and multiple tests. Science Teacher: Pattie Dickenson. Palm Springs Unified School District Alexa Gamble, 8th grade at Raymond Cree Middle School. Project: Think Before You Drink. Alexa observed someone at a public park holding their dog up and letting it drink from the drinking fountain. She began to wonder what the optimal time would be for household bleach to disinfect drinking fountains. Her hypothesis was that the longer the bleach was in contact with the fountain, the greater the disinfection would be. She tested samples taken at two, five and ten minutes. Her hypothesis was not proven because the data revealed that five minutes was the optimal time to disinfect the fountain, not ten. Science Teacher: Clint Wyatt Palm Desert Charter Middle School students get on the road, lear In February, nearly 500 7th grade students from Palm Desert Charter Middle School (PDCMS) had the opportunity to learn about what began as the economic backbone of the Coachella Valley – farming and agriculture. A quick walk through the David Harbison Lush & Efficient Garden lead the students to the Control Room where they were able to see how every aspect of water within the district’s boundaries is monitored and controlled through microwave telemetry. done in the Coachella Valley. Many of the students had never seen this part of the valley before. Over the course of three days, nine buses filled with students, teachers and parent chaperones visited various agriculture-related facilities. Before leaving PDCMS, the students received a brief history of the area surrounding their campus and how it was once covered with date and citrus orchards rather than all the homes we see today. A visit to the Coachella Canal let the students experience the wonder of how a 123-mile long canal can flow exclusively by gravity to its final destination at Lake Cahuilla in La Quinta. A visit to a farm gave the students a better understanding of how micro-irrigation is a highly efficient way to farm in the hot desert climate of the Coachella Valley. From the farm, they travelled to a refrigeration and packing facility where lemons were being packed and readied for shipment to destinations around the globe. The view from the canal, overlooking the agricultural area, gave the students a greater appreciation for how much farming is A final stop at Lake Cahuilla gave the students some time to relax, and have lunch before heading back to school. Buses were boarded and the students headed to CVWD’s office where they learned about how the salty desert soil has been transformed into land that can produce high quality crops and how Colorado River water is delivered from the Coachella Canal to each 40-acre parcel of farmland.
