Usage Method:
Just add water. The ratio of water to artificial snow powder is: 1:28. Pour the materials into a cup, add water, and you can have pure snowflakes in a moment. A small package can get a lot of snow. After it dries, collect it and you can use it again next time.

What is artificial snow?
Artificial snow is a magical type of water-absorbent resin that can turn water into a white, fluffy substance that looks just like real snow. This snow is now commonly used in movies and indoor decorations.
This artificial snow is a type of polymer chemical, where the term "poly" means a long chain molecule (from the Greek word "poly" meaning many, and "mer" meaning an individual or molecule). Artificial snow uses its permeability to water (where water molecules penetrate into it). When water molecules come into contact with the polymer, they cause it to swell from the outside to the inside. The polymer chains are elastic, but they can only stretch to a certain length before they cannot be further elongated.

Teaching Objectives
 
1 Understand the scientific name of water-absorbing powder
2 can perform simple magic tricks using water-absorbent powder (disappearing water)
Teaching Key Points
Understanding the physical characteristics of water-absorbent powder and its applications in daily life
This class focuses on performance, cultivating children's performance and expression skills.
Three - Teaching Process
 
1. Water-absorbent Powder: The full name of water-absorbent resin is a new type of functional polymer material. It has the ability to absorb hundreds to thousands of times its own weight in water.
 
High water absorption capacity of thousands of times, and excellent water retention performance.
 
2 Performance Steps
 
A uses props as paper cups × 2, a small amount of absorbent powder, and a small amount of clean water.
 
Before performing B, first pour a small amount of absorbent powder into a paper cup, and then stack the two cups together (with the cup containing the absorbent powder on top).
 
Enter the stage
 
C explains what the magic trick is, introduces the prop, and can invert the paper cup to prove it's empty when introducing it.
 
of
 
Pour a small amount of water into another paper cup, and then let the children check if it is ordinary water.
 
After checking E, pour the water into a cup with absorbent powder, gently shake it, and say the magic spell you think of.
 
Squeeze the F for about 10 seconds or so, until you feel that the absorbent powder has absorbed water and solidified. Then, slowly invert the cup over, and we will...
 
The water in the cup has disappeared.
 
Four - Knowledge Expansion
 
Superabsorbent resins have a wide range of applications and a very promising future. At present, their main use is still in hygiene products (absorbent pads, diapers, etc.)
 
Waterproof paper (diapers, etc.)
 
Due to the high water-absorbing capacity and excellent water-retaining performance of superabsorbent polymers, they are used as soil water retention agents.
The application of high-absorbent polyacrylic acid sodium in agriculture and forestry is very wide. If a small amount of this material is added to the soil,
 
can improve the germination rate of certain legumes and the drought resistance of bean sprouts, enhancing the soil's aeration performance. Additionally,
 
Due to the hydrophilicity of superabsorbent resins and their excellent anti-fogging and anti-condensation properties, they can also be used as new packaging materials.
 
Material. Packaging films made from high-absorbent polymers have unique properties that can effectively maintain the freshness of food. In chemical
 
The addition of a small amount of high-absorbent polymers to cosmetics can also increase the viscosity of the emulsion, making it an ideal thickener.
 
Utilizing the characteristic of superabsorbent polymers that only absorb water and not oil or organic solvents, they can also be used as dehydrating agents in industry.

Artificial snow is a high-tech chemical product. The product is in the form of fine particles, and after absorbing water, it looks exactly like real snow, which is pure white and crystal clear. It does not melt at high temperatures, feels cool to the touch, and has the feeling of snow. Moreover, it is non-toxic and harmless. This product can also be used for decoration of shopping counter, Christmas decoration, film and television, stage scenery, and so on.
