How do you introduce diffusion to students?

There are some great demonstrations to observe diffusion. Give students a stop clock and ask them to record when they first smell deodorant that has been sprayed in the middle of the class. If you also get students to raise their hands when they first smell the deodorant you will get a lovely ‘ mexican wave’ effect.

What is diffusion in plants for kids?

“Diffusion is the process of movement of molecules from a region of higher concentration to a region of lower concentration.” Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells.

What is diffusion explain with two examples?

(a) Diffusion is the mixing of a substance with another substance due to the motion of its particles. The smell of perfume spreads over a whole room is an example for diffusion. (b) Gases diffuse fast because of the large space between the particles in gases and high kinetic energy.

How do you explain diffusion?

Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and out of cells.

How do u explain diffusion?

How do you describe diffusion?

Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration [34].

What is the concept of diffusion?

diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.

What is diffusion explain with an activity?

Diffusion is a process of mixing of two different fluids into one another. In the activity when we add few drops of ink in water we see water changes its color or say the ink gets completely dissolved in water after some time.

Which is the best definition of diffusion?

Diffusion can be defined as the movement of molecules from an area of their higher concentration to an area of their lower concentration. So, the correct answer is ‘Movement of molecules from an area of their higher concentration to an area of their lower concentration’.

What is the process of diffusion?

Diffusion refers to the process in which particles from a higher concentration tend to move or transport to a lower concentration medium in order to attain the equilibrium. In diffusion, the concentration is equalized throughout the medium. Now we will try to understand this process of diffusion with the help of a diagram given below

What is stimulus in expansion diffusion?

To help you remember the name of this type, think of stimulus as a stimulating new idea that sparks another culture to use it and also motivates them to adapt it for their own purpose. Expansion diffusion and its various forms are not the only way that ideas and practices are passed along to others.

What is the end result of diffusion in sociology?

The end result of this diffusion is that people, as part of a social system, adopt a new idea, behavior, or product. Adoption means that a person does something differently than what they had previously (i.e., purchase or use a new product, acquire and perform a new behavior, etc.).

What are the different types of cultural diffusion?

Many cultural practices are spread by a type of cultural diffusion called expansion diffusion. This is when a trend is spread from its originating place, outward. There are several forms of this type of diffusion: contagious, hierarchical, and stimulus diffusion.
