Adherence
Adherence refers to the ability of an object or substance to stick to a surface. In the context of science, adherence is often studied in relation to materials and their ability to adhere to each other or to other surfaces.
Factors Affecting Adherence
- Surface Texture: The texture of a surface can affect how well another material adheres to it. A smooth surface may have different adherence properties compared to a rough surface.
- Chemical Composition: The chemical composition of the materials involved can impact adherence. Similar or compatible compositions may lead to better adherence.
- Pressure and Temperature: Applying pressure or altering temperature conditions can influence adherence between materials.
- Moisture and Contaminants: The presence of moisture or contaminants on surfaces can affect adherence properties.
Examples of Adherence
Adherence can be observed in various everyday situations:
- Adhesive materials sticking to surfaces.
- Paint adhering to walls or other surfaces.
- Tape sticking to paper or other materials.
- Barnacles adhering to the hulls of ships.
Study Guide
If you're studying adherence, here are some key points to focus on:
- Define adherence and its significance in science and everyday life.
- Identify and describe the factors that can affect adherence between materials.
- Provide examples of adherence in different contexts.
- Discuss the importance of understanding adherence properties in various fields such as engineering, biology, and materials science.

Second Grade: Focus on Systems and System Models; Energy and Matter
Earth and Space Sciences: Students develop an understanding of the distribution and role of water and wind in weather, shaping the land, and where organisms live. Wind and water can also change environments, and students learn humans and other organisms can change environments too. Students develop an understanding of changing patterns in the sky including the position of Sun, Moon, and stars, and the apparent shape of the Moon.
Earth and Space Standards
Develop and use models to represent that water can exist in different states and is found in oceans, glaciers, lakes, rivers, ponds, and the atmosphere.
