Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...

Teach your class the descriptive characteristics of soil. Provide information about particle size and a flow chart for assessing texture. Soil scientists then analyze samples and hypothesize which would be the best type for a rain...

Students explore different types of trees with their senses. In this nature lesson, students play a game in which pairs use their senses to explore trees, blindfolded. Students then must find the tree they found when blindfolded. 

You will find a viewer-friendly PowerPoint on the growth rings and other features found in a cross-section of a tree trunk, affectionately known as a "tree cookie." A few worksheets are provided for practice counting tree rings and a...

Seventh graders identify and examine a deciduous and coniferous tree. Using the descriptions, they discover the types of tress in their local area. As a class, they practice identifying trees on a walk in a park collecting leaves. They...
