By: Katelyn G.Year: 2024School: Sage HillGrade: 11Science Teacher: Beril Tekin In the vast expanse of the cosmos, where stars twinkle against the infinite canvas of space, lies a treasure trove of mysteries waiting to be unraveled. Among these enigmatic entities are exoplanets, celestial bodies orbiting stars beyond our solar system. For centuries, humanity gazed at the night sky, …
By: Elaine C.Year: 2023School: Arnold O. Beckman HighGrade: 10Science Teacher: Phillip Chow The number of M-dwarf stars is about eight times that of G stars, to which our Sun belongs. The main-sequence lifetime of M-dwarf stars is also ten times that of G stars. Yet we see a “yellow” star rather than a “red” star. This research used …
By: Eesha N.Year: 2023School: Serrano IntermediateGrade: 7Science Teacher: Andi Suter People have long been captivated by the idea of life beyond our planet, and our solar system’s moons, Europa and Enceladus, have emerged as promising candidates for the search for extraterrestrial life. Eesha’s intriguing science project delves into this quest by comparing data sets from these moons and …
By: Zoe T.Year: 2023School: Laguna Beach HighGrade: 9Science Teacher: Jennifer Park In the world of astronomy, the discovery of exoplanets has opened up new frontiers in our understanding of the universe. However, the accuracy of identifying exoplanets using transit photometry has been hindered by false positives, leading to the need for more effective analysis methods. Zoe, a talented …
By: Anshul A.Year: 2022School: Portola HighGrade: 11 Science Teacher: John Olivares Gravitational waves are a fundamental concept in astrophysics, which refers to the ripples in the fabric of space-time caused by the revolution of two binary black holes, two binary neutron stars, or a combination of both orbiting around a center axis. These waves were first predicted by Albert …
By: Philip S.Year: 2022School: Oxford AcademyGrade: 11 Science Teacher: Kim Nguyen Light is an essential element that allows us to see the world around us. However, the behavior of light can be quite complex, especially when it interacts with different media. Lateral shift is a phenomenon that occurs when light travels from one medium to another and then back …
By: Jacqueline Z.Year: 2021School: Venado MiddleGrade: 8Science Teacher: Emma Zschunke ABSTRACTAudible notifications and alarms have become popular as technology advances. This experiment examines the relationship between the amplitude, or volume, of a sound, and its respective frequency, or pitch, to improve auditory updates, such as wildfire evacuation updates, by adjusting their frequency.Using an online tone …
By: Arya K, Victoria C. & Rania A.Year: 2000School: Plaza Vista, 6t gradeDivision: Junior Does the color of a liquid affect its evaporation rate? We wanted to find out if the color of a liquid would affect how fast or slow it evaporated. We predict that the color of a liquid will affect its evaporation …
By: Leo A.Year: 2000School: Fairmont Private Schools Anaheim HIlls Campus, 7th gradeDivision: JuniorAdvisor: Mrs. Conklin The key to bending any type of wave (sound, light, or water) is to guide it through a gap. This experiment looks at whether small or large slits are more effective at bending waves. The purpose of this experiment is …
