### Summary Notes: Osmosis and Diffusion
**Lesson Objectives:**
1. Investigate and differentiate between osmosis and diffusion through hands-on activities and observations.
2. Understand the impact of both processes in biological and environmental contexts.
---
**Key Concepts:**
1. **Diffusion:**
- Definition: The movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.
- Examples:
- Spreading of perfume in a room.
- Nutrient absorption in cells.
- Impact:
- Essential for processes like gas exchange and nutrient distribution in organisms.
2. **Osmosis:**
- Definition: A specific type of diffusion that refers to the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
- Examples:
- Plant roots absorbing water from the soil.
- Maintaining turgor pressure in plant cells.
- Impact:
- Critical for maintaining cell structure and function in living organisms.
---
**Hands-On Activities:**
- **Activity 1: Osmosis Observation**
- Use potato slices in different concentrations of saltwater to observe changes in weight and texture.
- **Activity 2: Diffusion Experiment**
- Drop food coloring into water and observe how it spreads over time.
---
**Biological and Environmental Context:**
- Both osmosis and diffusion are fundamental processes that influence cellular functions, homeostasis, and ecological interactions.
- Understanding these processes can help us analyze real-world scenarios such as:
- Saltwater vs. freshwater environments for aquatic life.
- Effects of pollution on osmosis in plants.
**Conclusion:**
Osmosis and diffusion are crucial processes in nature, with significant implications for biological systems and environmental health. Through experimental observation, students will gain a deeper understanding of these phenomena.
