Amy and I are in the middle of a 3 year journey across North America by canoe, kayak, and dogsled. Each night we set up our tent in a new location and we travel about 20 miles each day. Our goal is to explore North America's wildest places to learn about the plants, animals, and people living in these amazing places.

Every day we are confronted by new challenges and we need you to help us come up with ways to solve these problems. This week we have two problems that we need your help with. After you have thought about them and discussed them with your classmates please submit your answers using the comment form at the bottom of the page, or email your answers to dave (at) wildernessclassroom.com.

Problem #1

What kinds of data should we collect?

Each week we record data to share with you. We will post this data in our Notes From The Trail every Monday. In the past we have recorded miles traveled, animals seen, weather data, what we eat, and many other things. However, we have a limited amount of time and battery power for our computers, so we need you to let us know what types data you want us to record. Please send us a list of things you would like us to record and share with you each week.

Problem #2

Help! The water is covered in green algae!8_24_11algae

In some parts of the lake you can barely see the water because the algae is so thick.

The water in Lake Winnipeg is full of algae and lots of sediment. We are in the middle of the lake now and we have learned that farther south there is even more algae. We normally collect our drinking water from the lakes and rivers we are traveling on, but we are afraid to drink the water out of Lake Winnipeg because the algae produces toxins that can make us sick. What should we do? How can we get clean water to drink?

Thank you for your help! We are looking forward to reading your creative solutions to our problems.

Keep Exploring!

Dave
