Use sodium polyacrylate

Math

• The student learned about the concept of volume and capacity while exploring the water absorption capacity of sodium polyacrylate.
• They practiced measurement and data analysis skills by recording the changes in volume of water as sodium polyacrylate absorbed it.
• They applied the concept of ratios and proportions when comparing the amount of water absorbed by different quantities of sodium polyacrylate.
• The student also learned about the concept of mass and weight when comparing the weight of sodium polyacrylate before and after absorption of water.

Science

• The student gained an understanding of the properties of sodium polyacrylate and its ability to absorb water, relating to the concept of polymers and their applications.
• They practiced scientific inquiry and experimentation by observing and recording the behavior of sodium polyacrylate in water.
• The activity facilitated understanding of environmental science, as the use of sodium polyacrylate in various products and its implications for water conservation were discussed.
