Title: What's Wrong With Global Climate Change? I Like it Warm!
Description: Students will identify factors that affect the solubility of a salt and test one of the factors (temperature). They will apply their experience to ocean salinity, the effects of temperature on the composition of ocean water, and what effects that could have.

Title: Magic Milk
Description: This lesson is designed to engage students in a discussion and demonstration of molecules, surface tension, and bonding.  Students will use hands-on materials as well as technology.  This lesson shows how a solution works to achieve equilibrium.  This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

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: Which Came First, Ice Cream or Refrigeration?
Description: As students begin their study of states of matter, this hands-on activity demonstrates how the interaction of a solid and a liquid can reverse the initial state of each material.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.

Title: Drying Dishes
Description: In this Science Update, from Science NetLinks, you'll hear how a quirk of dish drying shows off a fundamental idea behind the chemistry of water. Because of their different compositions, plastic takes a lot longer to dry than glass. 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.

Title: Determine Reaction Rates
Digital Tool: Reaction Rate
Digital Tool Description: The Reaction Rate for a given chemical reaction is the measure of the change in concentration of the reactants or the change in concentration of the products per unit time. The reaction rate can be determined by measuring how fast the concentration of A or B decreases, or by how fast the concentration of AB increases.

Title: Reaction Rates Affected by Temperatures
Digital Tool: Smart exchange-Chemical Reaction Rate
Digital Tool Description: The Reaction Rate for a given chemical reaction is the measure of the change in concentration of the reactants or the change in concentration of the products per unit time. The reaction rate can be determined by measuring how fast the concentration of A or B decreases, or by how fast the concentration of AB increases.

Magic Milk
Overview:
This podcast is a student-based project.  This project explains the magic milk lab.  The students lead a step by step explanation of the magic milk lab.  This podcast gives students a visual aid.  This will help them understand what is happening while they are learning about the chemistry of the lesson.

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!

Candy Flamethrower
Overview:
When chemicals react a number of things can happen:  two liquids can form a solid, a gas can be produced, things can change color, OR materials can combust. This video shows what happens when we place an organic substance (a material with a "carbon backbone" like sugar, or wood) into a particular hot and liquefied "oxidizer". The results are extremely exothermic, over 1,500 degrees F exothermic.
