Cloud Opacity Experiment

An experiment to demonstrate the differences in the way sunlight interacts with clouds of varying opacity, and how that impacts surface temperature.

Cloud Teller

Learn about the different types of clouds with this paper fortune teller.


Create a sky scene using materials like wax paper, fabric and paper, and learn about the different characteristics of clouds.

NASA GLOBE Clouds Family Guide

A collection of resources to help families observe clouds together.

Sky Conditions

Demonstrate how aerosols affect visibility using water and milk.

Clouds or Snow: A Satellite Mystery

This issue of Earth Observatory for Kids explains how clouds and snow can look the same from a distance, and how satellites can tell the difference by measuring light that humans cannot see. The accompanying activity is "Make Your Own Cloud (In a Bottle)"

Watch a video demonstration of the cloud in a bottle activity.

Air Quality Campaign Webinars

This four-part Air Quality Campaign Webinar Series, “Investigating GLOBE Air Quality from the Ground, to Clouds to Satellites,” originally presented November 2020-January 2021, provides information and tools for exploring air quality. Led by the GLOBE Clouds team at NASA Langley Research Center, it also includes presentations by various scientists and researchers on air quality topics.

Build a Dust Storm in a Tray Activity Demo

[8:03] Dust storms take place in many locations around the world and can be quite dangerous. In this video you will learn more about dust storms with atmospheric scientist Marilé Colón Robles, and you also will learn how you can safely observe them as a citizen scientist.

How to take dust observations with GLOBE Observer

Cloud Cover Estimation Activity Demo

[7:29] Jessica Taylor of NASA Langley Research Center and her two daughters show you how to do a Cloud Cover Estimation activity using simple materials. Supplies you need are paper (white and blue), scissors, glue or tape, and a marker or pencil.

Clouds Science Playlist

A playlist of five videos with experts explaining the science of clouds and the connections to citizen science, including Jessica Taylor, principal investigator for GLOBE Clouds, on "What is Citizen Science?" [4:08], Dr. Kristopher Bedka on "Clouds and Weather" [9:48], Dr. Patrick Taylor on "Clouds and Earth's Climate" [7:44], Dr. Kristina Pistone on "Clouds and Aerosols [5:24], Dr. J. Brant Dodson on "Clouds Research and Citizen Science" [7:40], and Dr. Bill Smith on “The Solar Terminator Problem” [8:16].

Correlation Between GLOBE Citizen Science and NASA Satellite Observations

[1:49] In this animation, data from Aqua, CALIPSO, CloudSat and GLOBE Observer are combined to show how multiple observations reveal the structure of clouds.


GLOBE Clouds: Getting Started

[2:35] This short video describes how to use the GLOBE Observer app to observe clouds and includes helpful tips.

GLOBE Cloud Science

[2:45] Atmospheric scientist, Jessica Taylor, describes how clouds affect our weather and climate and explains how your cloud observations help scientists study clouds.

NASA Behind the Science: Dr. Yolanda Shea

[9:59] Dr. Yolanda Shea shares how watching the weather forecast led her to a career as a NASA scientist. Dr. Shea uses remote sensing to study the role of clouds in Earth's climate.

Precipitation Connections

Use these videos from the Global Precipitation Measurement mission to make connections between clouds and precipitation. "Anatomy of a Raindrop" talks about the shape of a raindrop and why it is important for satellites like GPM to be able to measure the size of a raindrop, "For Good Measure" provides examples of how rain affects our lives and explains how NASA uses satellites to study precipitation, and "Show Me the Water" breaks down how much of Earth's water is usable and why studying precipitation is important for preparing for extreme weather, like flooding or drought.

Satellite Matching

[12:13] Marilé Colón Robles (GLOBE Clouds project scientist, NASA Langley Research Center) and Tina Rogerson (scientific programmer and GLOBE Clouds data manager, NASA Langley Research Center) share why satellite matches to GLOBE cloud observations are important and how they are done. Then, Heather Mortimer (GLOBE Observer graphic designer and science writer, NASA Goddard Space Flight Center) walks us through her own cloud observations and satellite matches.

Volunteer Scientist Panel Video

[11:10] A video showcasing stories from GLOBE volunteers about how they got started with GLOBE and the GLOBE Observer app, and connections they have made to research and to using GLOBE in their communities. This was originally shown as part of the GLOBE Observer Connection-Conversation-Celebration (C3) event held on 26 July 2022.
