Sixth-graders quest for river and lake knowledge

Lincoln Park sixth-grader Aidon Persson submerges his hand in ice water to feel the effects of hypothermia. In the "Cold Hand Luke" station, the Army Corps of Engineers educated students about hypothermia and water safety. The students plunged their arms in the ice water for one minute to feel the effects of hypothermia on their skin. (Photo by Teri Cadeau)1 / 7

Dave Carlson of the Duluth Sail and Power Squadron holds up a red bell pepper, asking the students if they think it will float. This station taught kids the importance of wearing a lifejacket when out on the water. Carlson demonstrated how different fruits and vegetables sink or float depending on their outer skin. "A good life jacket, is like that skin. It keeps you from sinking to the bottom, like that potato," Carlson said. (Photo by Teri Cadeau)4 / 7

Are you smarter than a sixth-grader? See if you can answer these questions:

1. An example of a negative buoyancy object would be a) a rock; b) a ping pong ball; c) a raft; d) a wooden barrel.

2. To get to the Twin Ports, oceangoing vessels ("salties") must navigate how many sets of locks on the Great Lakes St. Lawrence Seaway?

3. What river is the hydrologic connection between the Superior National Forest to the estuary that the Duluth-Superior Harbor is part of?

4. What travels in a storm sewer system and what travels in a sanitary sewer system? a) rain and snowmelt water; b) house and industrial sewage; c) bathwater; d) wastewater.

Busloads of area sixth-graders from around the Twin Ports found the answers to these and more questions about the Duluth-Superior Harbor at River Quest this week, May 9 -12. The students learned about the St. Louis River estuary as they moved through a dozen learning stations on land and on water.

The 24th annual St. Louis River Quest drew a record 1,495 students from 14 area schools to the waterfront this year. During each morning and afternoon session, small groups of students moved through a total of 12 unique stations — six aboard the Vista Star and six inside Pioneer Hall at the DECC — where students were introduced to topics ranging from pollution prevention and stopping aquatic invaders to personal water safety and commercial shipping. They all carried River Quest passports to document their adventures. After the event, students are encouraged to submit essays or poems about their experiences for an annual writing contest.
