Title: Mentos, Soda, and Nucleation
Description: In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students will then work in groups to determine what their hypothesis is about what is happening and why. The students will be given a chance to debate with other students about why their hypothesis is correct. This lesson could be used in eighth grade physical science, physical science, chemistry, and/or physics.

Title: Cold Car Start     
Description: In this Science Update, from Science NetLinks, you'll hear how wind chill affects car engines. Wind makes the temperature feel colder because it carries heat away from our bodies; it affects car engines in a similar way. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Exploding Pumpkin
Overview:
This short video demonstrates the power of chemical reactions.  The clip was recorded on the Saturday after Thanksgiving, 2006, when the Exploreum staff decided to do a little playing with our food. We called it Left Over Science. When calcium carbide is added to water it causes a chemical reaction.  After a short wait, a spark is added.  The result:  we blew up a pumpkin and we got it on video!
