Swelling Polymers Activity:

In this experiment, students learn how to create swelling polymers using two chemical substances, A and B. These substances react to form a polymer material that expands and forms bubble-like shapes. The experiment helps students understand the mechanism of chemical reactions and how these polymers are applied in various industries.

Absorbent Polymers Activity:

This experiment focuses on exploring the ability of absorbent polymers to absorb large amounts of liquids. Polymer powder is added to water, turning into a gel that soaks up the liquid. The activity allows students to understand how polymers work in liquid absorption and their applications in daily life, such as diapers and agriculture.

Magic Sand Activity:

In this experiment, fine sand is used with a water-repellent coating to create “magic sand,” which interacts with water to form a clay-like paste, then returns to its dry state once removed from the water. The experiment helps students understand how hydrophobic materials affect the sand's ability to absorb water and change its physical properties.
