Matter+and+Energy,+Changes+in+Property

Students will observe and record the effects of heating and cooling. Students will know that adding or taking away heat energy will change materials.

//**Generalizations: **//


 * Heating materials can cause them to melt or change in some other way.
 * Cooling materials can cause them to freeze or change in some other way.
 * We can record observations and discuss how materials are changed by heating and cooling.

//**Essential Questions: **//


 * What happens to materials when they are heated?
 * What happens to materials when they are cooled?
 * What can we observe and record about materials when they are heated or cooled?

 * __Key Definitions__**


 * change** = be or make different than before


 * cold**= having little or no warmth


 * cooling** = lowering in temperature; getting hotter


 * energy** = when added to a material, energy causes the materials to feel warmer


 * heating** = rising in temperature; getting hotter


 * hot** = having warmth


 * melt** = change from a solid to a liquid


 * observe** = using our senses to learn about the world around us


 * temperature** = how hot or cold something is


 * touch** = when we sense by feeling


 * water** = a clear liquid
