Plant A Tree

Never underestimate the power of a tree! Besides giving us an amazing array of paper and wood products, trees provide a host of other benefits—from shading our backyards to assisting in the maintenance of the global climate. Students can express their appreciation of trees by planning and carrying out their own tree-planting project.

Plants are All Around Us-How Many Little Seeds Math Task Activity #2

Students explore the concept of addition and subtraction combining and dividing seeds in a pot. Students pretend to be busy gardeners, adding seeds to the pot to plant and grow, or hungry birds, swooping down from high above to subtract seeds from the pot to eat.

How Big is Your Carbon Footprint?

People have become so accustomed to their diet, cars, homes, and energy usage that they don’t realize that the Earth will not be able to provide the needed resources indefinitely. When students go online to...

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...

Biodiversity, Invasive Species, and Plant Biosecurity-Activity #3

The presentation focuses on biodiversity, how invasive species affect biodiversity, who is involved in detecting invasive species, and plant biosecurity.  It also features other plant biosecurity issues such as those that affect our food supply, the USDA Select Agents and Toxins list, and agroterrorism events of the last century. Students...

Species that Cause Change in the Environment-Beneficial vs. Harmful (Activity #2)

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 in which students complete a workbook assignment.

They also draw all of the existing trees on their school’s block. In addition, students...
