Lesson Summary:
This guided inquiry lesson enables students to construct their own understanding of the classification of matter based upon the composition and arrangement of particles of matter. Students are able to actively learn the material without lecture or note taking.

Part 1: Elements vs Compounds
• Students investigate a colorful handout illustrating the particles of elements and compounds. They are asked to determine the difference between the particles of the elements and the particles of the compounds. The students discuss and record their observations.

• Students examine and sort twelve colorful cards into groups of elements and compounds based on differences in the compositions of their particles. They record the results of their card sort by sketching the card illustrations.

• Using shapes to represent atoms, students predict and illustrate the particles of different elements and compounds given written descriptions of the elements and compounds.

Part 2: Pure Substances vs Mixtures
• Students investigate a colorful handout illustrating the particles of pure substances and mixtures. They are asked to determine the difference between the particles of pure substances and the particles of mixtures. The students discuss and record their observations.

• Students examine and sort twelve colorful cards into groups of pure substances and mixtures based on differences in their particles. They record the results of their card sort by sketching the card illustrations.

• Students examine and sort twelve color cards of mixtures into groups of: mixtures of elements, mixtures of compounds, and mixtures of both elements and compounds. They record the results of their card sort by sketching the card illustrations.

• Using shapes to represent atoms, students predict and illustrate the particles of different pure substances and mixtures given written descriptions of the pure substances and mixtures.

Part 3: Homogeneous Mixtures vs Heterogeneous Mixtures
• Students investigate a colorful handout illustrating the particle arrangements of homogeneous and heterogeneous mixtures. They are asked to determine the difference between the arrangement of particles in homogeneous mixtures and the arrangement of particles in heterogeneous mixtures. The students discuss and record their observations.

• Students examine and re-sort the twelve colorful mixture cards into groups of homogeneous mixtures and heterogeneous mixtures based on differences in particle arrangement. They record the results of their card sort by sketching the card illustrations.

• Students identify particle illustrations as representing one of the following types of matter: pure substance composed of elements,
pure substance composed of compounds, homogeneous or heterogeneous mixture of elements, homogeneous or heterogeneous mixture of compounds, homogeneous or heterogeneous mixture of elements and compounds.

Student Study Sheet
Students are provided with a student study sheet summarizing all of the important concepts and vocabulary in this lesson.

*****************************************************************************

Learning Objectives (Bloom’s Revised Taxonomy):
Remembering: Identify similarities and differences between the particles of: elements and compounds,
pure substances and mixtures, homogeneous and heterogeneous mixtures.
Understanding: Explain the following terms as they relate to the classification of matter: matter, particle, atom, element, compound, pure substance, mixture, homogeneous mixture, heterogeneous mixture.
Applying: Classify illustrations of matter as elements or compounds, pure substances or mixtures, heterogeneous or homogeneous mixtures.
Analyzing: Differentiate between: elements and compounds, based on the types of atoms in their particles;
pure substances and mixtures, based on their particle composition; homogeneous and heterogeneous mixtures, based on the distribution of their particles.
Evaluating: Discuss how differences in particle composition and arrangement form the basis for the classification of matter.
Creating: Given general descriptions, predict and illustrate the composition and arrangement of the particles of:
elements and compounds, pure substances and mixtures
