  • Two Seniors Present Research in Far West Texas!

    Two Seniors Present Research in Far West Texas!

    Paschal High School seniors Mark Moses and Coleman Odom traveled to Sul Ross State University this past weekend in Alpine, Texas. They presented research posters at the Texas Herpetological Society Fall Symposium. The only high school students in attendance, all other presenters were graduate students or professional biologists! 

    Mark Moses coauthored a poster with science teacher Andrew Brinker that documented movement in the Clear Fork of the Trinity River between recaptures. The results supported the literature on home range and movement between sexes and age classes. The average movement was 674 meters for recaptured males and 433 meters for recaptured females. Large males moved the most at 808 meters between recaptures whereas small females moved the least at 204 meters between recaptures. 

    Coleman Odom coauthored a poster with TCU graduate student Shelly Wu and Paschal science teacher Andrew Brinker that identified 8 different taxa of diatoms in fecal samples of red-eared sliders. The education department at the Botanical Research Institute of Texas allowed Paschal to borrow a portable scanning electron microscope for a week. During that time several students and teachers used the microscope, and Coleman was able to use it for this research project. 

    After the symposium was over, the students traveled to Big Bend National Park for a field trip. At the park students were able to find and photograph the rare Big Bend Slider along with loggerhead shrikes and cactus wrens. After a five mile hike down the window trail the students returned to the Davis Mountains State Park where they camped for the symposium. 

    Congratulations to these students for such an outstanding accomplishment!

    Thank you to the TCU Andrews Institute of Mathematics and Science Education for funding this innovative educational project. Thank you to Texas Parks and Wildlife Department for scientific research permits. Thank you to Tarrant Regional Water District for permits to conduct this research downtown Fort Worth on the Trinity Trails. Thank you to BRIT and Hitachi for providing the students with an opportunity to work with the scanning electron microscope. Thank you to FWISD and Paschal High School for supporting this educational adventure.

  • Science Team Travels to San Antonio over Spring Break

    Posted by Whitney Smith on 3/18/2019

    Twelve science club members traveled to San Antonio March 15 and 16th for the Texas Math and Science Coaches Association annual meet. After an evening on the River Walk students spent the following day competing in both math and science events (Penta club was also well represented). When the dust settled, we were proud of a 6th place finish out of 35 teams in the 6A division. We will be competing for a second consecutive District Championship on March 30th.

    Posted by Whitney Smith on 2/20/2019

    Wednesday February 20th, four Paschal Science Club students presented their research at the Fort Worth Sierra Club meeting. Senior Katherine Faulkner discussed her research on diatoms (algae) living on the carapace of turtles. Junior Mark Moses talked about turtle recaptures and movement in the river. Juniors Nick Etheridge and Jake Harper discussed how they were able to determine the mercury concentrations in turtles with help from TCU Biology professor Dr. Chumchal. Thanks to the Sierra club for inviting us to speak!

  • Paschal Senior invited to Prestigious Research Symposium

    Posted by Whitney Smith on 1/23/2019

    Senior Katherine Faulkner

    Senior Katherine Faulkner is only the second Paschal student to receive an invitation to the Texas Junior Science & Humanities Symposium. The Texas Junior Science & Humanities Symposium promotes original research and experimentation in the sciences, engineering, and mathematics at the high school level, and publicly recognizes students for outstanding achievement. Texas JSHS provides an opportunity for Texas high school students to present the results of their original research in a professional arena. Katherine's research paper was "The Environmental Implications of the Fossil and Contemporary Diatoms of Royal, Nebraska". Diatoms are a type of algae that are considered keystone species in aquatic ecosystems as they makeup the base of the food chain. Diatoms are also used as indicator species to help determine water quality. The advisor and mentor on this research project was Shelly Wu, a PhD student at TCU and expert in diatoms. Congratulations to Katherine for this outstanding research!

2017-2018 Accomplishments

  • Olympiad Semifinalists

    Posted by Whitney Smith on 4/11/2018

    Two Students are Semifinalists in Olympiad!

     As the premiere biology competition for high school students in the United States, the USA Biology Olympiad (USABO) enriches the life science education of nearly 10,000 talented students annually. It provides the motivation, curricular resources, and skills training to take them beyond their classroom experience to the level of international competitiveness.

     Holley Anderson and Andy Ryu were chosen based upon their Open Exam Scores as semifinalists and recently completed the second round of the competition. Ultimately 20 students are chosen to attend a training at University of California at San Diego, with the top four traveling to Tehran, Iran from July 15 to 22, 2018 representing the United States.

  • Students present on Trinity River Turtle Survey

    Posted by Whitney Smith on 3/1/2018

    A collaboration between TCU graduate student Shelly Wu and Paschal students Katherine Faulkner and Taha Sharaf resulted in a poster presentation at the Informal Science Educator Association conference hosted by the Botanical Research Institute of Texas. This research is part of the Trinity River Turtle Survey, a mark-recapture study of turtles in the trinity river. This specific project was studying the diatoms (a type of algae) on the back of the turtle shells captured during the survey. Diatoms are a critical component of aquatic ecosystems as they make up the bottom of the food chain, similar to plants in a terrestrial ecosystem. They also act as indicator species, which can be used to determine the water quality.

    Posted by Holly Shipman on 2/8/2018

    After skipping January due to illness, the team was back at the Trinity River Friday morning with temperatures in the low 30's. Unfortunately the cold weather caused the turtles to lose their appetites. No turtles were trapped today, but it was still a fantastic morning. The students continued to rack up field experience and practice setting up/taking down turtle traps. There were tons of birds at the study site, and we did manage to capture one fish in the turtle traps!

    The PHS Trinity River Survey completed the third survey on December 17th. Despite the cold weather we managed to trap two male cooters! The front claws on male cooters are unusually long and used for courtship, making it easy to identify the sex of individuals.
