Objective
By the end of this lesson, you will be able to explore and understand the properties of balloons, including their behavior with and without helium.
Materials and Prep
- Balloons (both helium-filled and regular)
- A pump or straw to inflate the balloons
- A large open space to play and experiment
Before starting the lesson, make sure you have a basic understanding of how to inflate the balloons and tie them securely.
Activities
Start by inflating a regular balloon using the pump or straw. Observe how the balloon behaves when released without any additional force.
Inflate a balloon with helium and compare its behavior to the regular balloon. Discuss the differences you observe, such as the balloon floating in the air.
Experiment with different sizes of balloons and observe how their behavior changes. Does the size of the balloon affect how it moves through the air?
Try to keep a balloon in the air without using your hands. Use your body, breath, or other objects to keep it afloat. How long can you keep the balloon from touching the ground?
Challenge yourself to create a game or a dance routine using the balloons. Can you incorporate different movements and keep the balloons in motion?
Fifth Grade Talking Points
"Balloons are made of a flexible material that can be inflated with air or helium."
"Helium is a gas that is lighter than air, which is why balloons filled with helium float."
"The size of a balloon can affect how it moves through the air. Larger balloons may move slower, while smaller balloons may be more agile."
"When playing with balloons, we can use our bodies, breath, or other objects to keep them afloat and create fun games or routines."
"By experimenting with different types of balloons and observing their behavior, we can learn about the properties of air and gases."
