This document discusses classifying substances as elements or compounds. It provides definitions of elements, compounds, and mixtures. Elements are composed of only one type of atom and cannot be broken down further, while compounds are made of two or more types of atoms bonded together. Mixtures are made of two or more elements or compounds physically combined. The document outlines an activity where students will sort symbol cards into elements and compounds based on these definitions. They will then define elements and compounds based on the sorting rule.

9. Activity Time
 Prepare a scissor and glue.
 Read carefully the INTRODUCTION in the worksheet.
Matter can be classified into pure substances and mixtures.
Pure substances can be elements or compounds. An
element is composed of only one type of atom and cannot
be broken down into smaller pieces. A compound is made
from two or more types of atoms that are bonded together.
A compound can be separated by chemical means. Mixtures
are made of two or more different elements or compounds
physically combined. Mixtures can be separated into their
parts by physical means.

10. Activity Time
Follow the steps in the PROCEDURE.
1. Prepare all the materials needed.
2. Cut the set of symbol cards in the worksheet.
3. Sort the cards into two groups based on the symbols shown.
4. Create a “rule” in grouping the symbol cards.
5. Label the symbol cards as “Elements” and “Compounds”.
6. Paste the correct sorted cards on the worksheet labeled as “Elements” and
“Compounds”.
7. Write your own definition of elements and compounds based on the rule you
used.
8. Answer Guide questions 1-3 and Summary/Conclusion
