Terra Bagga
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....

Terra Bagga
One way to identify possible volcanic activity on other planets is by testing the planet for magnetism. A science lesson begins with pupils constructing their own planet from a dead battery, magnets, paper, and tape before labeling...

Carbon, Greenhouse Gases, and Climate
Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Water in the Atmosphere
A slide show serves as the backdrop for a lesson 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 observations and...

Bacteria Take Over and Down
Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Air Pressure
Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

Ring of Fire
Over a period of 35 years, earthquakes and volcanoes combined only accounted for 1.5 percent of the deaths from natural disasters in the United States. The 15th lesson in a 20-part series connects the locations of earthquakes and...
Science 4 Inquiry
The Ins and Outs of Photosynthesis
The most important chemical process on Earth is photosynthesis. Scholars explore the changes in the gases in our atmosphere as life on Earth developed. They create a model of photosynthesis and consider simple questions.

Weathering of Limestone
We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Water Supply
Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

Modeling Sizes of Planets
The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Happy Landings: A Splash or a Splat?
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,...

Slip Slidin' Away
Students investigate mechanical weathering as a form of erosion. In this erosion lesson, students, define weathering and erosion before determining how the Earth's surface is in a constant state of change. They watch a video, access...
