STUDENT SUCCESS The Charles Herbert Flowers Science Department is dedicated to providing the resources students need in order to succeed. We understand student success is dependent not only upon effective instruction and planning but also identifying and providing key interventions to assist students when formative assessment demonstrates deficiencies in mastery. Each sub-department provides 2 hours of after school tutoring per week provided by subject area instructors. Through partnerships with stakeholders such as University of Maryland and Prince Georges Community College, we also have volunteer tutors who come in and work with our students to enhance their skills in science.
ANNUAL SCIENCE FAIR Spotlights the efforts of our students in science, technology and engineering
Students work on individually designed and implemented research, analyze data, and present their work in
this fair.
Through partnerships with Food and Drug Administration, National Institutes of Health, NASA and other
related private and federal agencies judges volunteer their time and expertise and score the students’ work
Judges also form relationships with our students and serve as mentors in research projects and other
school and career focuses.
Winners of the Charles Herbert Flowers science fair go on to compete at the regional Prince Georges County
Science Fair. As a result, we have had numerous students receive awards, scholarships and gift certificates for
the work they have done.
Collaboration with other departments in the school. The Art department designs the programs, the TV
Productions team publicizes the event and the Culinary Arts Department Pro-Start Students provide lunch for
our judges and participants providing time for further collaboration and networking.
SCIENCE FAIR HIGHLIGHTS
RESEARCH PRACTICUM SYMPOSIUM
Students focus on yearlong research with mentors in laboratories
in various private industry and government agencies
Students present research and data in a formal symposium before
an audience of peers, mentors and educators
Tagged Mutation Approach to Study the Pathogenecity of a Fungus Fusarium Oxysporum fsp.gladioli
Methodology 1. Two week old culture was grown in FOG isolates in PDA at 22 C. 2.Gladiolus corms were taken out from cold room and acclimatized at room temperature in the dark the day before the experiment. 3. 5ml sterile distilled water was added to isolates and scraped mildly with a scrapper. 1 ml of spore suspension was collected on a 1.5 ml sterile eppendorf tube. 4. Spore suspension was stirred by flicking 5 times and then the sterile lancet needle was dipped in the suspension and pricked to defined depth on the periphery of the corm. 5.Corms were artificially wound at four sites 6.Corms were incubated at 22 C for 3 days in the dark. Corms were then put in brown paper bags and kept at room temperature in the dark. 7.Measurement of external diameter of infection of the corms were taken and then corms were cut into two halves. 8. Measurement of the depth and spread of infection were taken. Pictures were taken when needed. 9.After 4-6 weeks of infection, evaluation was done by using disease rating scale ranging from 1 to 5, 1 being no infection and 5 being 51-100% of the surface covered with mycelium.
Findings The transformed FOG clones showed wide variations of pathogenecity when inoculated to gladiolus corms.
Conclusion The transformed FOG clones showed wide variations of pathogenicity when inoculated to gladiolus corms. Some of the transformed FOG clones were more pathogenic than the wild type (i.e., untransformed) FOG isolate, whereas, some transformed FOG clones were less pathogenic than the wild type FOG. This observation supported the hypothesis that Agrobacterium-mediated genetic transformation of the fungus also caused mutations in the pathogen. In future, the high or low virulence FOG clones will be utilized to molecularly identify the site of mutations in the fungus and thereby, correlate those genes for pathogenecity of the fungus on gladiolus corms. This will enable the plant pathologists to develop better control methods against the pathogen.
Introduction Agrobacterium tumefacien (A.tumefaciens) is a plant pathogenic bacterium present in soil which causes crown galls and tumors in plants. Its ability to cause tumors in plants is due to the transferring of certain genes residing in the extra-chromosomal element called Ti-plasmid. The new genes are transplanted at random locations in the host chromosomes. Researchers have engineered this bacterium to inactivate its gall-producing ability without affecting its ability to transfer any gene(s) of interest. In the process of introducing novel genes, the A. tumefaciens also causes random mutations by disruption at the site of integration on any host gene.
