A Chinese lantern is a good model. A lightweight enclosed 'envelope' with a heat source suspended below it.
tie a red balloon to a small cup or bastket
air is heavier than balloon, air rises
The volume of air increases on its heating hence the balloon rises on heating
-- Inflate the balloon with some substance that is less dense than air. OR -- Inflate the balloon with air, then heat it after it is sealed.
Hot air goes into the balloon. sense the air is so hot, it pushes the balloon off the ground and floats in the air!
You could name it, The Burning Hot Air Balloon:)

to make a hot air balloon rise you use hot air
The volume of air increases on its heating hence the balloon rises on heating
You could make a papier-mache air plane.

Simple...hot air rises..
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
Hot air goes into the balloon. sense the air is so hot, it pushes the balloon off the ground and floats in the air!
Balloon Morphing is when your balloon has ran out of air,and not even knowing it,so you figure it out in like a project.Do some research because I need some research on this project.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
