Species that Cause Change in the Environment-Beneficial vs. Harmful (Activity #3)

A 30-minute presentation focuses on how some species (native and introduced) are beneficial to the environment, while others (native and introduced) are actually detrimental (harmful) to the environment.  The presentation is followed by an activity where students complete an online e-learning module and associated handout.

Arthropod (insect/spider/bug) identification and activity guide

This resource is an eight-page (two printed 8.5X11 sheets), accurately illustrated guide to subphyla of North American arthropods and explains how taxonomy works.

i-Tree Unit Lesson 1: Water Cycle and Weather

This lesson emphasizes how evaporation affects precipitation which contributes to heavy rain and storms. It lays the foundation for thinking about the ways that trees can mitigate increased weather effects in urban environments like Washington, D.C. First, students discuss their past observations of evaporation and write a hypothesis to describe...

i-Tree Unit Lesson 2: Evaporation Lab

At the conclusion of Lesson 1: Water Cycle & Weather, students were asked the question: “How does temperature affect evaporation?” Students review the water cycle and how it affects the weather, conduct the evaporation lab and describe the factors that affect evaporation.

From Seeds to Plants

Primary unit on plants. In this activity students use observational skills to compare and discuss the changes in plants. They will identify plant parts, where seeds come from and how they grow. They will also determine what plants need to survive.

Tree-Mendous Trees (Lesson 2)

Using knowledge of tree parts gained in Lesson 1, students collect tree parts and use them to identify the tree using specified books.  Students then create a display and present results to the class.

i-Tree Unit Lesson 3: Carbon Footprint

Through the experiment conducted in Lesson 2: Evaporation Lab, students concluded that higher atmospheric temperature causes an increase in evaporation which results in more precipitation. In Lesson 3, students first calculate the carbon footprint of their morning commute to school to realize that different modes of transportation produce varying...

TreEAB Week 1, Lesson 3: How trees grow

At the end of this mini-unit, students will understand all the ecosystems services and value trees provide to humans every day. Students will know the biological processes of trees and the importance of native trees for providing habitat. Finally, they will acknowledge the significance trees add to our surroundings and be able to share everything...

Beetle Busters-Community Leaders (Lesson 1)

Students use ALB ID Cards to create labeled diagrams of key ALB characteristics.  They then complete a Classification Tree comparing the ALB with native insects.

Nature Works Everywhere Gardens Activity Guide: Habitat and Pollinators

Students learn how the garden provides habitat for a variety of different animal species. They make observations and collect data to determine which species inhabit the garden (especially pollinators), investigate relationships among them, and identify factors that may affect them. They use this data to track species over a period of time to...
