Featured Reviews

“We loved learning about the different trees especially the mysterious tree. We learned how our body systems are similar to those of the tree. ”
· Adriana · Teacher
“We loved the way we had to work together and analyze information to solve the puzzle. We also loved learning about different kinds of trees and seeing how they survive.”
· Briana · Homeschooler
“This lesson was great no only was it hands on but students had to apply what they learned to answer the questions about the forest.”
· Nikole · Teacher
“I enjoyed experimenting with the model in this lesson. It helped me understand how the parts in trees work together as a system to help them survive in a particular environment.”
· Autumn · Teacher
“I took the kids outside to look at different trees and especially their roots. I really liked the Roots chart because we discussed how and why roots would grow the way they do. The video with the rain really helped with the explanation on why roots would grow horizontally or vertically.”
· Donna · Teacher
“Students loved it and made them think! Asked really good questions. ”
· Melissa · Teacher
“The hands on and the easy prep for this was wonderful. It kept the students active and gave great step by step directions. The materials required were simple and cheap but poignant for getting the point across. This is much appreciated as a science teacher who has to prepare many activities with lots of supplies.”
· Cheryl · Teacher
“I really appreciated the example of structure and looking at the unusual tree with a complex trunk system. This was a great way to explain and have kids ponder structure.”
· Dorene · Teacher
“We enjoyed learning about the different types of roots and how deep or shallow they can grow and how that translates to the environment that they are able to live in. We loved learning about the snow conditions and how trees are able to survive in the snow and also how some trees can survive in water like on the beach.”
· Taj · Homeschooler
“My students had a lot of fun doing this lesson. They especially enjoyed the experimental part with the branches.”
· Lisa · Teacher

Activity Prep

Print Prep
In this lesson, students make observations of external and internal parts of trees in order to collect evidence that these structures work together as a system to help plants survive in a particular environment. In the activity, Tree Detective, students use models of roots and branches to explore their functions and then construct an argument about how these structures must work together in order to support the survival of trees in the unique environment of the frozen taiga.
