Rate of Dissolution Activities for Middle School Science

The Kesler Science Rate of Dissolution 5E Lesson is a comprehensive, student-led chemistry unit designed to explore how temperature, surface area, and agitation impact the rate of dissolution in aqueous solutions. This low-prep, editable lesson includes presentations, worksheets, assessments, and student-choice projects, ensuring differentiated and multimodal learning. 

Following the 5E Model, students engage with objectives and word wall vocabulary in English and Spanish before exploring key concepts through a hands-on, differentiated station lab. With nine stations, students investigate dissolution through experiments, reading passages, research, video analysis, categorization tasks, writing prompts, illustrations, and assessments. A challenge station offers extension activities for early finishers. 

Explanation materials include editable PowerPoints, interactive notebook templates, and note-taking guides in both English and Spanish. Students elaborate on their learning through choice projects comparing dissolution factors, while STAAR 2.0-aligned assessments and review worksheets ensure mastery. 

Designed for flexible use in both classroom and virtual settings, this lesson aligns with TEKS 7.6E and provides everything needed for an engaging and effective chemistry unit.

Engage your students with this modular, student-led station lab aligned with TEKS 7.6E. Designed for in-class or virtual learning, this lesson explores how temperature, surface area, and agitation affect the rate of dissolution of solid solutes in aqueous solutions through interactive stations.

Students take charge of their learning as they complete nine differentiated stations featuring videos, readings, research, hands-on activities, and assessments. They demonstrate understanding by organizing information, illustrating models, writing responses, and completing assessments. A bonus challenge station provides extension activities, and English and Spanish reading passages support differentiated instruction.

This low-prep, high-engagement resource fosters critical thinking and active learning.

The Rate of Dissolution Student Choice Projects align with the 2021 TEKS standard 7.6E, allowing middle school students to select a project that suits their preferred output style. A project page outlines six student-led options plus a “design your own” project, all with an editable rubric for teacher, peer, or self-assessment.   

These flexible, multimodal projects provide creative ways for students to demonstrate their understanding. Two versions of the project page support differentiation, with modified options for students needing remediation and challenge options for advanced learners. Teachers can adjust the rubric to fit grading needs.  

The projects use standard classroom supplies like paper, markers, and scissors, and many options are available for digital completion.
