Erupting Volcano - Sick Science! #070

More than 80 percent of the earth's surface originated from volcanoes. The 16th lesson in a 20-part series introduces the shape and development of volcanoes. It begins with a demonstration using a balloon and flour to illustrate the...

Three major types of volcanoes exist: cinder cone, composite/strata, and shield. The 18th lesson in a 20-part series covers the various landforms created from volcanoes. Scholars work in pairs to correctly identify the three...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...

Want to add a wow factor to your current chemical changes lesson plan? Try a microscale experiment with colorful precipitates! Partnered learners conduct 10 single displacement reactions and record their observations.

Thinking back to the last time you taught a lesson on chemical changes ... was there no reaction? Check out an explosive video to put some spark back in your instruction! The narrator of the video guides you through the...

Why is it so difficult to make two solid compounds react? Investigate the concepts of particle collisions and rate of reaction using a quick demonstration. The colorful experiment features two plain, white solids combining to form a...

Blow the roof off your classroom with this multimedia science lesson on volcanic eruptions. A short online video teaches young geologists about shield and composite volcanoes and explores the examples of Kilauea and Mt. Vesuvius,...

Take your class inside a beaker for an up-close view of a chemical reaction! Junior chemists examine how chemical reactions occur using an interactive resource. The activity allows users to change the temperature and observe how it...

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...
