Hooked On Science – Bouncing Bubble
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.
• 9 oz Clear Plastic Cup
• Dishwashing Liquid
• Bubble Wand
• Cotton Glove
STEP 1: Fill the clear plastic cup 1/2 of the way with water. Describe and classify the water by its observable properties.
STEP 2: Fill the clear plastic cup 1/4 of the way with dishwashing liquid. Describe and classify the dishwashing liquid by its observable properties.
STEP 3: Add 1 teaspoon of glycerin to the clear plastic cup and mix to create a bubble solution. Describe and classify the bubble solution by its observable properties.
STEP 4: Place the cotton glove on your hand.
STEP 5: Using the bubble wand, blow bubbles. Describe and classify the bubbles by their observable properties.
STEP 6: Catch a bubble and bounce the bubble on the cotton glove. Describe how the bubble can be used as a model to describe that matter is made of particles too small to be seen.
A bubble is a thin film of soapy water, filled with air. A bubble contains three main layers. Sandwiched between two soapy layers, is a layer of water. Bubbles burst when this layer of water evaporates. The glycerin creates bonds with the water molecules, slowing down evaporation, creating a stronger bubble. The glove prevents the bubble from hitting your hand, which may contain dirt and oil. The dirt and oil, from your hand, will cause a bubble to burst.
