     Instead of hitting the beach, fourteen high school students traded swimming suits for lab coats last

summer and turned their attention to scientific experiments.

     The High School Research Program offers high school students guidance with researchers in Texas

A&M's College of Agriculture and Life Sciences. Jennifer Funkhouser, academic adviser for the Department

of Rangeland Ecology and Management, direst this four-week summer program designed to increase

understanding of research and its career potential (潜能).

     Several considerations go into selecting students, including grades, school involvement and interest in

science and agriculture. And many students come from poorer school districts, Funkhouser says. "This is

their chance to learn techniques and do experiments they never would have a chance to do in high school."

     Warner Ervin of Houston is interested in animal science and learned how to tell male from female

mosquitoes(蚊子). His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight

against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school

students.

     The agricultural research at A&M differs from stereotypes. It's "molecular (分子) science on the cutting

edge," Funkhouser says. The program broadened students' knowledge. Victor Garcia of Rio Grande City

hopes to become a biology teacher and says he learned a lot about chemistry from the program.

     At the end of the program, the students presented papers on their research. They're also paid $600 for

their work-another way this program differs from others, which often charge a fee.

     Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and

plowing and that research can open many doors.
