St. Lawrence River
On board, sailors!
How was the St. Lawrence River formed? Where is its source? Is it fresh water or salt water? Why are there a lot of whales in Tadoussac? Together, we will find out the answers to these fascinating questions through five exciting experiments that focus on the differences in size of the five Great Lakes, water filtration, the river’s salt content, bank erosion and water density! We will then sail from the Great Lakes to the Atlantic Ocean on one of the world’s most dangerous sea routes!
For 30 more minutes:
Let’s continue our exploration of the St. Lawrence River by travelling along its banks in the Bas-du-Fleuve region to build a wind farm as in Cape Cat.
Objectives at the elementary level:
- Describe the location of natural freshwater sources and natural sources of salt water.
- Illustrate the importance of the five Great Lakes of US and Canada.
- Define the following terms: “sources” “river mouth” “upstream” and “downstream”.
- Understand the water filtration system.
- Compare the different salinity zones of the St. Lawrence River and identify them on a map.
- Classify the different stages of a method for shoreline preservation of the St. Lawrence River.
- Illustrate the principle of water density of water.
- Access to an electrical outlet is required.
- A sink must be available in the area where the animation activities will take place.
- If there isn’t much time between animation activities, it is strongly recommended that they are set up in the same area.
- 5 teams must be formed before the science animator arrives. (60 min.)
- 6 teams must be formed before the science animator arrives. (90 min.)
