All Year Long Science Journal Activity

This activity shows how students will keep a science journal during each of the four seasons. Students will record observations of the general outdoor environment they visit and then will make observations of one specific item from the habitat in each season. At the end of the school year, students will make comparisons of their seasonal drawings and share their results with the class.

Build a Clinometer

Simple Instructions for how to build a paper clinometer (an instrument used to measure angles) and use it to calculate the height of a tree.

More detailed instructions from the GLOBE Teacher's Guide

Freeze/Thaw - The Breathing Boreal Forest

In this activity students play the role of coniferous trees. First they learn about seasonal freeze/thaw cycles and dormancy through a game of tag. Students then juggle complex environmental factors to try to survive a growing season in a changing climate. Connections between freeze/thaw cycles, photosynthesis and the global carbon cycle are explored.

Measure a Tree

What is the tallest object you can measure with a meterstick? A fence? The ceiling? Have you ever disagreed with someone about the height of a tree or building? If you work as a team, you can measure the height of any object!

Tree Height Comparisons: A Hand-Held Clinometer vs. the NASA GLOBE Observer Trees Tool

Taking great measurements and observations of tree height is vital to the accuracy of the science, to the comparison of the data to that of ICESat-2 and GEDI, and to the understanding of local to global impacts of trees on the environment. The objective is to do a comparison of the tree height measurements using a hand-held paper clinometer versus the NASA GLOBE Observer Trees Tool for citizen science and to explain any differences between the two measurement methods.

Tree Impact Study

Trees are among the oldest living organisms on Earth. Because of their size, complexity, and long life, trees provide a habitat, like an island, that rises far above the ground. Your goal in this study is to document the impact of a large tree on the environment of your school or community.

Using Trigonometry to Determine the Height of a Tall Object

Even though the NASA GO Trees Tool calculates the angles and tree height for you, please take a look at this great reference video that discusses the trigonometry used in calculating heights of tall object, like trees.

Amazon Canopy Comes to Life through Laser Data

[2:01] Flying and aircraft over the Brazilian Amazon with an instrument firing 300,000 laser pulses per second, NASA scientists have made the first 3D measurements of forest canopies in the region. With this research they hope to shed light on the effects of prolonged drought on forest ecosystems and to provide a potential preview of stresses on rainforests in a warming world.

NASA eClips Real World: The Carbon Cycle

[5:43] Carbon is an essential building block for life. Learning how carbon is converted through slow- and fast-moving cycles helps us understand how this life-sustaining element moves through the environment. Discover how NASA measures carbon through both field work and satellite imagery keeping watch through its eyes on the sky, on Earth, and in space.

The Adventures of Pho the Photon

[2:48] Pho, a plucky bright green photon of light, must travel from a NASA spacecraft down to Earth and back again to help complete a crucial science mission in this educational short film. The animation was created and produced by media art students from the Savannah College of Art in Design (SCAD) in Georgia, in collaboration with NASA’s Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) mission. Their goal was to communicate the science and engineering of the mission, slated for launch in 2018.

The GEDI Mission

[3:05] The Global Ecosystem Dynamics Investigation, or GEDI, uses advanced laser technology to reveal the makeup of remote forest ecosystems around the globe. Its measurements of the height of leaves, branches, trees, and shrubs below its path will help scientists map the structure of forests and better understand how ecosystems are storing or releasing carbon.

The Secret Life of Forests

[3:29] Forests in the United States are constantly changing. For four decades NASA and the U.S. Geological Survey's Landsat satellites have kept a steady watch from space, and now scientists are turning yearly data sets into powerful time series that show the evolution of the landscape. In this visualization of false color images taken of the Pacific Northwest from 1984 to 2011, scientists see many different stories.
