This is my first resource in booking virtual field trips at my school and let me tell you, they have some amazing experiences!

You do need a free account to log in but then to have access to a community full of resources. The trips are easy to arrange and facilitate. Some are better than others. My personal favourite has been with Thomas Edison’s laboratory and the trip was called Idea to Product. The tour took us behind the scenes into his labs, storage area, and office to demonstrate the design process. Other highlights include The Canadian Canoe Museum, the Elephant Sanctuary in Tennessee, and the Sea Turtle Hospital in Mission, Florida.
I have a trip booked with a class next week called “Walking with the Dinosaurs” and it takes place in India. For us in Brandon, Manitoba, we are pretty excited about what this might look like!
