Experimenting with Creek Engineering Models
"I think the creek covered in English Ivy looks less healthy because if there's only one type of plant, there can't be very many animals living there," explained Aris, a third grade student from Berkeley Arts Magnet Elementary School. Aris and his classmates learned about creek restoration engineering by comparing historic photographs of creeks to figure out what makes a creek healthy or unhealthy. Using sand box models, the students then investigated how a creek habitat can be drastically changed by human engineering techniques. One student, Hanna shared, "The concrete channel actually increased erosion and then there was no habitat left for the animals! What were people thinking?!" CONTINUE READING
