Second Grade Curriculum



As tree detectives students will discover clues about how trees are important in a habitat or community. They will start their journey by determining if trees are alive. They will then go on to explore using magnifying glasses, the living and nonliving things trees interact within their physical environment. Using thermometers they will discover how trees play a role in influencing temperature in a particular location.

By observing the tiny holes – stomata – on the underside of leaves they will learn that trees are essential to animal survival and that air occupies space. Finally using anemometer students will gain an understanding how energy, in the form of wind, can impact trees and their environment.


In the classroom students will investigate how fossils can tell us about the climate of Ohio long ago.

They will manipulate an interactive Ohio felt map to show a visualization of the Ice Age and how it changed over time. They will understand how the change in climate changed the trees and ultimately led to the extinction of the mastodon, giant beaver and stag moose.

Finally the students will plant tree seeds from the Ice Age and present day to observe in the classroom over time.


Students will investigate in the classroom where water comes from and the different parts of the water cycle. They will continue their investigation at Holden where they will discover that water travels through trees, and that trees are a part of the water cycle.

Students will discover the amount of water in the air (humidity), and how water molecules stick to each other and the natural object they land on. They will measure roots to learn the amount of water absorbed by a tree is determined by the length of the tree roots. Students will listen to the water traveling through the tree using a stethoscope. Finally, using cobalt chloride paper, they will understand that trees release water though tiny holes on the underside of the leaves.
