In this project, students will create balloon rockets to analyze how friction influences motion. By experimenting with different surfaces, they will observe variations in movement.
If the surface is smoother, then the balloon rocket will travel a longer distance due to reduced friction.

Set up a string across a room, secured at both ends.
Thread a straw through the string before tying it.
Inflate a balloon and pinch the end to keep air inside.
Tape the balloon to the straw, ensuring it can move along the string.
Release the balloon and observe its movement along the string.
Measure the distance traveled using the ruler.
Record the distance in the notebook.
Repeat the experiment on surfaces with different textures.
Compare distances to see how surface texture affects travel.
Analyze the data to determine the impact of friction.
Graph the results to illustrate findings.
Conclude based on observed data and report findings.
Balloon rockets should travel further on smoother surfaces, demonstrating that less friction allows for greater propulsion.

Be cautious when using scissors and handle balloons to avoid popping.
Use video recordings to show the rocket launches.
Prepare a visual comparison of distances traveled.
Explain the role of friction in everyday life.
Smooth surfaces reduce friction, allowing objects to move more freely.
Air pressure inside the balloon propels it forward as air escapes.
Yes, but ensure the string is secure and weather conditions are calm.
