GLE 0507.9.2 - Design and conduct an experiment to demonstrate how various types of matter freeze, melt, or evaporate. GLE 0507.9.3 - Investigate factors that affect the rate at which materials freeze, melt, or evaporate. GLE 0509.9.1 - Observe and measure the simple and chemical properties of common substances.


 * __Engineering Activities__**

__Ice Cream in a Bag__ - Given general materials (no measurements), SW attempt to create ice cream in a baggie.
 * Math integration - measurement, fractions

__Mystery Powders__ - SW experiment with plaster of paris, flour, cornstarch, baking soda and sugar using iodine, vinegar, and water. SW determine the effect of each liquid on each powder.
 * Math integration - graphing, measurement

__Baking Soda Balloons__ - SW experiment with vinegar and baking soda to inflate a balloon. Chemical change - creating gas.

__Crystals__ - SW observe the physical change of evaporation resulting in the formation of crystals.

__Potato Candle__ - TW construct candle out of potato and almond (wick). SW describe using only physical characteristics. TW use this as discrepant event.
