Hooked on Science - Mystery Cubes December 24TH – 30TH

INGREDIENTS

• 2 Ice Cubes

• 2 Transparent Drinking Glasses

• Water

• Isopropyl Alcohol

INSTRUCTIONS

STEP 1: Fill one of the transparent drinking glasses half the way with water. Describe and classify the water by its observable properties.

STEP 2: Fill the other transparent drinking glasses half the way with isopropyl alcohol. Describe and classify the isopropyl alcohol by its observable properties.

STEP 3: Drop one ice cue into the glass of water and the other ice cube into the glass of isopropyl alcohol. What happens? Describe and classify the ice by its observable properties.

The ice floats in the water and sinks in the isopropyl alcohol. The reason, the ice is less dense than water and more dense than isopropyl alcohol.

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 while doing 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.
