Encouraging all STEM Learners
Early this fall, I was contacted by one of the organizers of the Science Symposium for Girls here in Honolulu. She had seen me on the local news talking about my Arctic expedition as a Grosvenor Teacher Fellow, and she asked if I would be willing to present about the Arctic at this year's symposium. I could not pass up the opportunity to work with 5th-8th grade girls from island schools in the 2015 Science Symposium for Girls. The symposium, now in its 21st year, is presented by Sacred Hearts Academy in partnership with Bank of Hawaii Foundation.
Females are often discouraged from STEM (Science, Technology, Engineering, and Math) subjects in school and are still underrepresented in potentially lucrative STEM careers. But why? While inherent gender differences have been ruled out by science, multiple environmental and social barriers influence the complex issue of female participation and achievement in STEM subjects. According to current research, these factors include persistent gender-bias about traditional male and female fields, a fixed mindset rather than a growth mindset for intelligence, lack of spatial skills training for girls, and a lack of confidence and feeling of isolation for girls in STEM subjects.
My Symposium Workshop
I believe events like the symposium can not only boost girls' confidence in STEM but also help them develop relevant skills. Moreover, girls interested in STEM gain a sense of community through collaborative work. If we are going to increase our nation’s STEM participation and achievement, we need to support all learners! Therefore, I was honored to be invited to participate in today's symposium. As a featured presenter, I delivered a workshop to two different groups of 20 girls.
For my workshops, I decided to focus on sharing about my Arctic expedition with a Prezi for the first half of the session and use to second half for an ice inquiry investigation. First, I introduced how I was able to travel to the Arctic through a teacher fellowship through National Geographic and Lindblad Expeditions. Next, I defined the Arctic region and pointed out some facts about Svalbard, the land of the Ice Bears. I shared the Arctic scenery and wildlife through my expedition photos.
In my talk, I told the story of how the polar bear depends on sea ice for survival. These top predators rely on the sea ice in order to hunt seals. However, I explained to the girls that like the polar bear, our planet also depends on sea ice. One reason we need sea ice is critical habitat for Arctic wildlife, from crustaceans to seabirds to walrus to the iconic polar bear. Also, our ice-covered polar regions reflect much of the incoming solar radiation, regulating global climate. In addition, sea ice plays an important role in the ocean conveyor belt, the global transport of seawater.
Next came the hands-on part of the session! The ice inquiry allowed the girls to practice making predictions and then collecting data while investigating if an ice cube (dyed with blue food coloring so water is easier to observe) melts faster in fresh or salt water. We then discussed how temperature and salinity each affect density and related the concepts to the ocean conveyor belt. The girls in each session asked a lot of thoughtful questions about the Arctic and were really engaged in the lab portion as well. It was an awesome day of learning!
