1Compounds Science Anytime-Harcourt Brace Write On Grade 5
2Learner Expectations: Content Standard: 13.0 Interactions of MatterThe student will investigate the interactions of matter.Learning Expectations:13.1 Describe the types of changes that result from interactions of matter.
3In this activity you will: learn about compounds and how they are formed.write a paragraph using the facts that you find.
4CompoundsCompounds are formed when atoms of different elements are combined.When the elements are combined their identities change.
5Water: Water is formed from hydrogen and oxygen. Both elements are gases.When combined they turn to a liquid.Hence their identities change.
6Analogy:Think of elements as letters of the alphabet and compounds as words formed by combining the letters.We can spell all of the English words with just 26 letters.We can form millions of compounds with just 109 elements.Ex: Sodium(Na) + Chlorine(CI) = Salt(NaCI)
7Forming Compounds: What type of change occurs when forming compounds? Chemical changesDo the characteristics of an element change when combined with another?YesWhat happens when 2 or more elements combine and their properties change?A compound is formed
8Writing ActivityWrite a paragraph explaining how a compound is formed.Include the components combined to form the compound.Use the periodic table and give an example of a compound.
