Middle & High School Science Fair

Cabrillo Point Academy

We are very excited to introduce our four Science & Engineering Fair finalists who will go on to represent Cabrillo Point Academy at the Orange County Science & Engineering Fair (OCSEF)! Our Middle and High School students presented their projects to judges via a zoom meeting. They were poised, prepared and knowledgeable while they presented their amazing projects! Our judges were very impressed.

Please take a look and learn a little about their exceptional projects below!

Student Projects

Aria - 9th Grade

Building an AM Crystal Radio

Hypothesis: "I predict the longer the antenna, the better the radio signal."

Conclusion: "The initial hypothesis (the longer the antenna, the stronger the signal in the crystal radio) was supported by the data. The antenna of 100 feet produced the clearest signal to hear distinct voices. The antenna of 50 feet produced static voices and music. The 20 feet of antenna produced no signals."

Exploring Earthquakes. Project will explore the relationship between stress build up in the tectonic plates and the resulting size of the earthquakes along those fault lines.

Hypothesis: "If the force at or near a boundary is increased, then increased displacement along a fault will happen when the fault ruptures."

Conclusion: "The hypothesis was correct. While testing each of the different blocks, the data supported the initial hypothesis that increased friction at a fault would increase the displacement of the block during an earthquake. As the friction between the block and the board was increased by changing the sandpaper, the wood block required more stress before it moved. This increased friction is similar to that found along plate boundaries in the real world. As more stress was added to the rubber band, it caused more stress on the fault, which resulted in greater displacement once the block moved. Therefore, the data supports the initial hypothesis."

Landslide Early Warning System

Hypothesis: "An early warning system could save lives."

Conclusion: "This study proves that an early warning system could save lives if used in areas with high landslide probabilities."

Bio-mimicry in Action - Bio-Inspired Scouting Robots

Hypothesis: "Snakes inspired the first scouting robot because they move through cracks and small cervices frequently, with ease, which is necessary for scouting robots in small spaces. The other robot is based on quadruped animals because they have four stable points of contact with the ground, which gives them more stability in small spaces and unstable terrain. This would be very beneficial for the scouting robot. Therefore These unique designs of nature are what will give these robots the upper hand in real-world scenarios."

Conclusion: " Both of these robots proved that these unique locomotion types could be used, but they do have their limitations. These robots were strictly used to test these exciting types of locomotion. Therefore these robots do not consist of the necessary parts for real search

rescue missions. For example, the robots cannot be controlled from more than around fifteen to twenty feet away. With more research and development, these robots could be used in real-world situations. They would need to be upgraded with more substantial parts such as aluminum - instead of plastic. The motors would need to be more robust, more precise, and durable. Consequently, the quadrupedal robot’s leg motor broke due to the less durable parts in the motor."
