Inquiry in Action: M&m's in Different Sugar Solutions
An activity to investigate the factors that affect the rate of a substance dissolving. In this activity, students see if the rate of dissolving of the M&M coat is changed by the amount of sugar already dissolved in water. This...

Teach Engineering: How Much Sugar Is in Bubble Gum?
Most of the flavoring in gum is due to the sugar or other sweetener it contains. As gum is chewed, the sugar dissolves and is swallowed. After a piece of gum loses its flavor, it can be left to dry at room temperature and then the...

Science Buddies: What's the Point of Boiling?
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Science Alive: Pure Substances, Mixtures, and Separations
One way scientists talk about matter or substance-that is, the stuff in the world-is in terms of pure substances and mixtures. Pure substances are substances that contain only one kind of molecule. Water with nothing else in it is a pure...
Texas Instruments
Texas Instruments: A Sweet Drink Adventure 7
Students determine how the temperature of water affects the dissolving time of a sugar cube. They create, interpret and analyze graphs of data, find an equation of the line of best fit, and relate slope to rate of change.
