After predicting what – other than magic – caused Jack’s beanstalk to grow so tall, students design and conduct experiments to explore how different conditions affect plant growth. This open-ended investigation of conditions for plant growth assumes some student knowledge of basic plant needs (light, water, etc) and can be used as a springboard for… View More

As the St. Louis River flows into Lake Superior, it creates a freshwater estuary. This dynamic area can provide several important aquatic habitats; open water, sediment on the bottom and wetlands along the shoreline. Students will observe the characteristics of wetlands and estuaries through the use of a model and identify their importance to the health of aquatic… View More
