Rate of Dissolution Station Lab - New TEKS 7.6E

Keep your middle school students engaged, curious, and learning with this modular, student-led station lab on the rate of dissolution, aligned with TEKS 2021 standard 7.6E.
This comprehensive, ready-to-use resource saves you hours of prep time while allowing students to take ownership of their learning through inquiry-based exploration and hands-on investigation.

In this station lab, students will investigate and model how temperature, surface area, and agitation affect the rate of dissolution of solid solutes in aqueous solutions.
Perfect for in-class or virtual learning, this differentiated activity gives students multiple pathways to engage with chemistry concepts and apply them to real-world situations.

Differentiated, Modular, and Student-Led

Each station lab includes nine differentiated activities designed to create a personalized learning experience for every student.
In this student-centered format, the teacher serves as a facilitator—guiding learning rather than directing it—while students work independently or collaboratively to explore how variables impact the dissolving process.

The nine modular stations include all signage, reading passages, task cards, and resources for easy setup and smooth classroom flow.
The Explore It! station may require a few common materials you likely already have in your classroom.

Ready for In-Class or Virtual Learning

This resource is built for maximum flexibility, making it ideal for traditional, hybrid, or online instruction.
All digital materials are fully compatible with PowerPoint and Google Slides, so students can complete the lab seamlessly in any environment.

The Stations

Input Stations – Learn and Explore

Students encounter new concepts about the rate of dissolution through multiple learning modalities that promote engagement and comprehension.

• Explore It! – A hands-on demonstration or experiment connects content to real-world applications. In the digital version, students manipulate images and text in PowerPoint or Google Slides.

• Watch It! – Students watch a short, focused video and answer guided questions about factors affecting the dissolving process.

• Read It! – Students read a short passage about the rate of dissolution and respond to comprehension and vocabulary questions. Differentiated passages are available in English and Spanish for all reading levels.

• Research It! – Students explore data, graphs, and visuals that show how temperature, agitation, and surface area influence solubility, completing guided tasks on their lab sheets.

Output Stations – Apply and Demonstrate Understanding

Students show what they’ve learned through hands-on, visual, and written activities that deepen understanding and build retention.

• Organize It! – Classify and sort information using manipulatives or digital drag-and-drop tools.

• Illustrate It! – Draw or model representations of how different variables affect dissolution.

• Write It! – Respond to short-answer prompts using scientific vocabulary and complete sentences.

• Assess It! – Demonstrate mastery through task cards and written reflections that use key vocabulary in context.

Bonus Station – Challenge It!

Designed for early finishers and advanced learners, this station includes crosswords, mini-projects, and games that extend learning and encourage creative application of key concepts.
