Bubbles
_____________________________________________________________________________________________________________________________________
Standard I (Physical Science): Understand the structure and properties of matter, the characteristics of energy, and the interactions between matter and energy.
Performance Objective: Students will understand that when a force (e.g., gravity, friction) acts on an object, the object speeds up, slows down, or goes in a different direction.
_____________________________________________________________________________________________________________________________________
Demonstration/Background Information: The teacher will discuss forces in regards to direction. The reason certain objects go in a certain direction may depend on gravity, friction or anything that impedes it (Newton's 1st Law of Motion). She will demonstrate that when a book is dropped on the floor, it goes down and not up. She will then show her students the prepared jars or bottles of bubbles. She will explain to them that bubbles rise because the air inside them is warm from their bodies (from their breaths). As the air inside the bubble cools, they fall to the ground.
Activity: Blowing Bubbles
Question: What determines the direction in which blown bubbles with go?
Hypothesis: We think that our bubbles will _________________________________________________________________________________________________.
Materials: florist wire and a bubble mixture created by combining one cup of dishwashing liquid and eight cups of water. The teacher will prepare enough bubbles for an equal amount into 4 jars.
Safety Considerations: This activity is conducted outside. The main concern is ingestion of the soap mixture and spills that could cause slipping and falling. Also bubbles should not be blown into the face or eyes. These precautions must be understood before starting the activity.
Procedure: Students will work in groups of 3-4, gather materials and follow these steps:
1. Students will work in groups of 3-4.
2. Each student will construct their own wire wand.
3. Students will take turns blowing bubbles.
4. Students are encouraged to explore the types of bubbles that can be created by bending the florist wire into various shapes.
After students have completed their experiment, each team will meet to discuss their findings. They will then answer the following questions:
Effective Question:
What happened to the bubbles when the wand shape was changed? Were there any changes noticed? Explain your answer

Was your hypothesis correct? Why?
