Real World Science : The Science of Climate Change
<
br/>
This program begins by explaining how scientists have learned that Earth’s climate has changed many times over billions of years and that Earth’s climate is...

In this video, we learn about the water cycle and how water continually moves and changes from place to place and from phase to phase. The video explains the three main steps of the water cycle: evaporation, condensation, and...

In this video, we learn about the water cycle and how water travels from the earth to the air and back again. We explore where water is found on Earth, including oceans, glaciers, rivers, and underground. We also learn about the...

This live-action video program is about the term change of state. The program is designed to reinforce and support a student's comprehension and retention of the term change of state through use of video footage, photographs, diagrams...

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about the water cycle.

Upon viewing the The Changing Phases of Matter video series, students will be able to do the following: Explain that phases of matter, also called states of matter, are the physical forms matter can take. State the four phases of...

The 3 simple ingredients of sun, air and water lead to every type of weather on Earth. The atmosphere is constantly trying to balance heat from the sun with water vapor and air to create a dynamic planet. The unique properties of the...

The cycle of water from the air to the ground to the oceans and back to the air never ends. Water is found in the air, in the ground, in rivers and oceans, and it's found as gas, liquid, and solid. As it moves though phases and locations...

Climate is the average type of weather that a region has. It is defined by temperature and moisture. Proximity to oceans and large mountain ranges defines climate too, depending upon the prevailing wind. While climates change over...

Mars has been all over the news and media lately. It certainly looks like humans will set foot upon its surface very soon! Just in case you're one of the lucky people who get to go, you'd better learn all about the planet first, don't...

This beautiful program illustrates the key components of the water cycle that occurs everywhere around us. Concepts and terminology: condensation, evaporation, precipitation, cloud, rain, snow, sleet, and hail.

This series of videos takes students on a fascinating journey, following food as it travels through the digestive system. Clear animations illustrate the functions of the major digestive and excretory structures. Concepts and terminology...

A rainy day spent inside helps a little boy learn about clouds and the water cycle from his mother. He sees the value of rain to plants, animals, people and the planet, even when the rain is not convenient for him. As the rain...

Viewers take a trip above the earth's atmosphere to learn about weather around the world. Students will come to understand the relationship between water, air and heat and how they interact to make weather happen. The terms atmosphere,...

The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...

The Water Cycle part 1. Students will be able to do the following:

- Define the water cycle as the continual movement of water between earth and the
air.
- Explain that the water cycle consists of three processes:...

Everyday we use water. We drink water, use it to cook our food, and we use it to wash things. This video takes a look at the many important investigating water uses of water, while exploring its basic characteristics.
