• Teacher guide with class discussion prompts, engagement ideas, and notes on common misconceptions

Explore

Students take the lead in this student-centered, differentiated station lab designed to reach every learning style.
With nine interactive stations, students explore how matter can be classified by observing and comparing the physical properties of pure substances, elements, compounds, and mixtures.

Input Stations allow students to absorb information in multiple ways:

• Explore It! – Hands-on experiment or demonstration connecting new ideas through direct observation

• Read It! – Short, leveled reading passage with comprehension questions (English and Spanish versions included)

• Research It! – Guided online activity with structured questions and visuals

• Watch It! – Short, engaging video with discussion prompts and guided reflections

Output Stations allow students to apply learning in meaningful ways:

• Organize It! – Classify and sort examples using printable or digital card sorts

• Write It! – Respond to open-ended prompts using complete sentences and key vocabulary

• Illustrate It! – Draw and label diagrams to reinforce understanding of classification systems

• Assess It! – Demonstrate mastery through structured questions using vocabulary in context

Bonus Station – Challenge It!
Provide early finishers and advanced learners with extension activities, including puzzles, games, and mini-projects for enrichment and reinforcement.

Explain

Help students synthesize and apply their discoveries with guided instruction and reflection:

• Editable PowerPoints (standard and interactive versions)

• Interactive Notebook Templates in digital and printable formats (English and Spanish)

• Note-taking templates to scaffold student understanding and retention

Elaborate

Encourage critical thinking and creativity with student-choice projects that challenge students to name, classify, and compare types of pure substances and mixtures.
Projects can be completed in class or at home to extend learning beyond the lesson.

Evaluate

Reinforce mastery and assess understanding with:

• STAAR 2.0–style assessment questions in both standard and modified versions

• Review worksheets for test prep, homework, or class discussion
