Experiment 1 Sizes of Mini Air Balloons

Problem Statement
Does the size of a mini air balloon affect the time taken for it to fly?

What is the hypothesis
to be tested?
Therefore, the manipulated
variable is the size of a
The bigger the mini air balloon while the
size of a mini air responding variable is the
balloon, the longer time taken for a mini air
the time it takes to balloon to fly. The constant
fly.
variable is the type of paper
used to build the dome of
the mini air balloon.

Apparatus and Materials
• brown paper • double-sided tape
• card stock • fine wire
• ruler • wax burner
• marker pen • matches What are other variables that
• scissors • stopwatch can be made constant?

Steps
1. Make three mini air balloons of different sizes and label them A, B and C.
2. Test the mini air balloon by flying mini air balloon A.
3. Record the time taken for mini air balloon A to fly from the moment it floats
until it falls to the ground.
4. Repeat steps 2 and 3 with mini air balloons B and C.

Observation
Record your observations in the table as shown below.
