Middle School Chemistry: Can Gases Dissolve in Water?

Find out if liquids can dissolve in water.

An activity through which students learn why gas is able to dissolve in water, and how heat affects the solubility of a gas in a liquid.

Lesson plan with mulitmedia links in which students identify and control variables to help design a solubility test for different liquids in water.

Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.

Lesson plan in which students design an experiment to determine if different types of liquids affect the amount of dissolution of an M&M candy shell.

Six middle school chemistry lessons about the periodic table and bonding complete with handouts and animations.

Young scholars determine whether a liquid will sink or float in water by comparing its density to the density of water.

Six interactive chemistry lessons about density complete with handouts and animations.

Students see a demonstration of a color change using universal pH indicator and then change the concentrations of an acid and a base using a universal indicator to test the pH of the resulting solutions. Through an animation, they see...
