13．Two teachers are sitting in a laboratory，their dirty hands buried in grass．Mary Richmond is a sixth grade science teacher at Cache LaPoudre Middle School in Laporte，Colo．Jolene McDowell teaches high school biology at Great Mills High School in Maryland．The two women have spent the past week doing science as part of the Research Experience for Teachers Program at the Toolik Field Station，only 188kilometers south of the Arctic Ocean．Armed with the research experience，they will be excited to head back to share their stories with their students about science in the Arctic in a few weeks．
For their two-week experience，Richmond and McDowell are living in a tent．So far，they have helped to set up a laboratory，processed soil samples and mounted other samples onto microscope slides．
"As teachers in the classroom，I think it's important for us to get out and do science，Richmond says．This experience has rekindled （重新点燃）her enthusiasm for science，she says．Richmond is looking forward to taking it back to the classroom．"If I'm excited about it，the kids are more likely to be excited about it，''she notes．And in her sixth grade classroom，enthusiasm is important．
"It's also important to show students that you want to learn and you're willing to put yourself out there and be uncomfortable，"explains McDowell．"I've never been this far north before．This is a location where you don't even flush（冲）your toilet paper．But I'm willing to be here to learn and experience something new，"she adds．
The Toolik research station brings in a different number of teachers each year．Openings are generally posted in March and can be found on the Natural Resource Ecology Laboratory website．
After their stay，the two teachers，along with others at research sites around the United States，will have a year to translate their experience to something for the classroom．They can add to their curriculum，make a presentation or come up with a class activity．
