What’s Included in Each 5E Stage

Engage

Capture students’ attention and spark curiosity:

• Objectives and Word Wall Cards in English and Spanish

• Teacher guide with discussion prompts, engaging activities, and common misconceptions to address

Explore

Students take the lead in a student-centered, differentiated station lab that meets every learning style.
With nine interactive stations, they’ll explore how to identify evidence of chemical changes—such as color changes, temperature shifts, gas production, or new substance formation—through hands-on and digital experiences.

Input Stations help students absorb information through multimodal learning:

• Explore It! – Hands-on demo or experiment that connects science concepts to real-world observations

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

• Research It! – Guided online activity where students collect and analyze data

• Watch It! – Short, engaging video with reflection questions and discussion prompts

Output Stations allow students to demonstrate their understanding:

• Organize It! – Categorize examples of physical vs. chemical changes using printable or digital card sorts

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

• Illustrate It! – Sketch or model evidence of chemical changes to reinforce understanding

• Assess It! – Apply concepts through vocabulary-based questions and written analysis

Bonus Station – Challenge It!
For early finishers or advanced learners, this enrichment station includes puzzles, mini-projects, and review games for deeper exploration and reinforcement.

Explain

Help students connect their discoveries to core concepts with:

• Editable PowerPoints (standard and interactive versions) with built-in differentiation

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

• Note-taking templates to support organization and comprehension

Elaborate

Encourage creativity and critical thinking with student-choice projects focused on identifying and describing chemical changes.
Students apply what they’ve learned through independent or collaborative projects—perfect for in-class or at-home learning extensions.

Evaluate

Reinforce understanding and assess mastery with:

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

• Review worksheets for test prep, discussions, or homework assignments

Perfect for In-Class or Virtual Learning
