Halt, Who Goes [in/out] There? Structure and Function of the Cell Membrane in Different Environments
by Lacey Merritt
The purpose of this lesson is to engage 7th-grade students in a hands-on investigation of how salt concentrations affect plant cells. By exploring the process of osmosis, students will gain a deeper understanding of cellular functions and the importance of maintaining homeostasis in living organisms. This lesson integrates science, technology, and math to provide a comprehensive learning experience that connects classroom concepts to real-world phenomena.
Outcome:
By the end of this lesson, students will have:
-Observed how varying salt concentrations impact the structure and function of red onion cells through microscopic examination.
-Conducted osmosis experiments using dialysis tubing and U-tubes to simulate cell membranes and water movement.
-Utilized PhET Interactive Simulations to model osmosis and gather additional data.
-Analyzed and graphed experimental data using 7th-grade math skills, identifying patterns and trends.
-Read and synthesized scientific articles to support their understanding of osmosis and homeostasis.
-Constructed and presented scientific explanations on how changes in a cell’s environment affect cellular function and overall organism health, highlighting the role of osmosis in maintaining homeostasis.
Through this integrated STEM investigation, students will develop critical thinking and problem-solving skills, enhance their ability to use technology in scientific inquiry, and gain a foundational understanding of key biological processes.
