Dive into the power of the sun with a two-part instructional activity. Budding scientists model the greenhouse effect in a hands-on activity, and then participate in a skit that explores the earth's energy balances and what really occurs...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

Students discover how wind is created on earth: changes in temperatures and air pressure. They list good and bad effects of the wind and make a weather vane and practice using it for 2 weeks.

Young scholars explore the states of water. For this science lesson, students use observation, measurement, and communication skills to describe water as it changes from a solid to a liquid.

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...

Students identify the biomes of the Earth and their characteristics. They discuss their favorite seasons and the weather. They share their favorites with the class.

Using the NASA website, class members try to determine if changes could be detected in cloud cover, temperature, and/or radiation measurements due to the lack of contrails that resulted from the halt in air traffic after the attacks...

How do the five themes of geography relate to the country of Iceland? Pupils learn about everything from the differences between relative and absolute location to how humans both adapt and change the environment. The presentation...

Students use data to determine if the climate in Portland has changed over the years.  For this weather lesson students complete line graphs and study long wave radiation. 

Why does it look like there is a man on the moon? Why does the moon look different every night? These are the focus questions of a lesson that prompts class members to observe and record the nightly changes of Earth's natural...

Students examine how Earth's rotation causes daily cycles in solar energy using a microset of satellite data to investigate the Earth's daily radiation budget and locating map locations using latitude and longitude coordinates.

Students become aware of the effects of tides on the Earth's rotation. In this tides lesson, students calculate the number of seconds lost over various periods of time.

Young scientists learn what it takes for life on Earth to survive with this series of photosynthesis resources. Offering twelve different activities ranging from independent practice worksheets to in depth scientific...

Learn the ins and outs of the properties of water through an engaging slide show. The lesson presents different facts about water including phase change, heat of fusion, heat of vaporization, and specific heat among others. 

A slide show serves as the backdrop for a instructional activity on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

The stability of the atmosphere changes on a daily basis. A kinesthetic lesson models how the stability of the air changes as it's warmed by the sun. Learners connect their models to the changing air currents and movement of warm and...

Students explore the relationship between the amount of water in the atmosphere available for precipitation and the actual precipitation observed by satellite. They examine seasonal changes in precipitation. They practice using Internet...

Earth science explorers design an experiment to demonstrate that the albedo of a surface affects its temperature. They test to find out if moisture on the surface affects temperature. They discover whether or not concrete or asphalt heat...

Beginning with a brief anticipatory set on how water is commonly used, this presentation evolves into a well planned lesson on the water cycle. Students will discuss vocabulary, label the parts of the water cycle, locate where water is...

Earth's magnetic poles switch positions about every 200,000—300,000 years. In the activity, groups create a planet with a magnetic field. Once made, they use a magnetometer to determine the orientation of the planet's magnetic field....

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...
