Earth Forces

Review some of Flinn Scientific products related to earth forces to determine how you can incorporate them as you create you next science lab.

Water Cycle Adventure - Super Value Kit, AP7675

Water Cycle Adventure - Super Value Kit shows how you can send your students on a quest to discover where water has been with this kit.

Stream Table, AP7684

Stream Table shows how you can use this product to teach students how water makes different geographical formations.

Earthquakes and Resonance

An earthquake with a magnitude of 8.5 struck Mexico on September 19, 1985. Mexico City, 250 miles from the epicenter, sustained considerable damage. A high percentage of 6- to 15-story buildings suffered damage while a very small number of one- and two-story buildings were damaged. A 48-story building experienced only minor damage—a few broken windows. While many variables affect the amount of damage a building suffers as a result of an earthquake, the natural frequency of a building is a major contributing factor.

Demonstrating Seismic Waves

Seismologists determine the location of the epicenter of an earthquake by studying seismograms which detect and record the vibrations of primary and secondary seismic waves traveling at different speeds. A super spring is a good demonstration device to help students compare and contrast the properties of P-waves and S-waves.

Where on Earth Is the Water?

Use this simple demonstration to shock students about the distribution of fresh water.

Wind Erosion

Why is there so much dirt in the air after a farmer harvests a crop? This is the result of wind erosion.

Chemical Weathering

Why is Washington, DC’s magestic Lincoln Memorial starting to deteriorate? Could it be the result of acid rain, a type of chemical weathering?

Mechanical Weathering

How does a large boulder become sediment? Through a process called weathering, larger particles are broken down by chemical and physical means.

Are You Under Pressure?

Have you ever wondered why the Earth’s atmosphere is sometimes referred to as an “ocean of air”? Should the word ocean be used to describe a gas? Could this ocean of air also be the specific cause of structures and functions of various species? Test your students’ powers of observation and deduction by doing this inexpensive exercise.

Mini-Geyser

What are geysers? How do they work? In this demonstration, an actual working model of a geyser will be constructed.

Ocean Water Properties

What is the difference between water of high salinity and water of low salinity? What effect does density have on water currents? Perform simple activities to answer these questions.

Great Glaciers

What are glaciers and how do they form? What effects do glaciers have on the land? In this demonstration, a simulated glacier will be constructed and used to help answer these questions.

A Cloud in the Hand...

An exquisitely simple demonstration in which you literally form a cloud with your own two hands. The thunder and lightning are up to you.
