Hooked on Science - Disappearing Water (July 30, 2018 - August 5, 2018)

INGREDIENTS

• 2 Plastic Glasses
• Sodium Polyacrylate
• Water

INSTRUCTIONS

STEP 1: Pour a teaspoon of sodium polyacrylate into one of the plastic cups. Describe and classify the sodium polyacrylate by its observable properties.
STEP 2: Fill the other plastic cup ¾ of the way with water.
STEP 3: Quickly pour the water into the cup containing the sodium polyacrylate and observe.
STEP 4: Dump the contents of the cup onto a flat surface.
Describe and classify what you see by its observable properties.

EXPLANATION

The sodium polyacrylate absorbs the water, creating a slush-like material. Sodium polyacrylate is a super-absorbent polymer, which is found in disposable baby diaper.

SCIENCE SAFETY

PLEASE follow these safety precautions when doing any science experiment.

• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any experiment.
• NEVER eat or drink anything when performing any experiment.
• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
