Children experiment with freezing water to observe a state change of water, and discover that it is less dense as a solid (ice) than it is as a liquid (water). Amazing Expanding Ice is an overnight activity requiring 20 minutes of preparation, overnight freezing of the experiment, and 10 minutes of follow-up discussion.

CLIM - Climate models In this video clip, a scientific expert tells us about climate models.

CLIM - Climate projections In this video clip, a scientific expert tells us about climate projections.

CLIM - Earth’s climate system In this video clip, a scientific expert tells us about the Earth’s climate system.

In this video clip, a scientific expert tells us about the ocean acidification. Catherine Jeandel, oceanographer, is a CNRS researcher (French National Centre for Scientific Research) and researcher director at LEGOS (Laboratoire d'Etudes en Géophysique et Océanographie Spatiales), Toulouse, France. CLIM is a series of videos created by the OCE, Dorothée Adam-Mazard, Claire Adam-Mazard and the production company WATTSON. The first serie of videos as part of the OCE educational project dedicated to the theme Ocean & Cryosphere, in the context of climate change.

Students observe which types of clouds are visible, how much of the sky is covered by clouds, and the opacity of clouds. They also report on surface and sky conditions, to complement views from satellites.

The purpose of this hands-on activity is to demonstrate that air has weight and how this fact can be concretely illustrated. Eventually and through more experience gained by conducting mind-engaging activities, the learner will come to a basic understanding that a given volume of air at higher elevations is less dense and has fewer molecules per volume than a similar volume at lower elevations.

This short video uses animated imagery from satellite remote sensing systems to illustrate that Earth is a complex, evolving body characterized by ceaseless change. Adapted from NASA, this visualization helps explain why understanding Earth as an integrated system of components and processes is essential to science education.

A suite of hands-on activities to give students the opportunity to describe the shape and appearance of clouds and learn the types of weather that are associated with clouds. The module includes outdoor observation, group work, and creative/artistic activities.

Several activities that introduce students to the concepts of earth as a series of systems that are all connected. All of the activities reinforce the idea that water, air, soil, and living things all interact in the Earth system. There are several components that educators can choose to use: a book, a play, two activities, and two coloring pages.

Learning activities help students explore and describe soil, consider what is found in soil such as rocks, roots, critters, and organic material, and explain the importance of soil to plants and animals.
