Ucar: Balloon Inside a Bottle

If you have seeds at home, try this activity to help kids learn what a seed needs to grow. Students will create experimental conditions in terrariums to study what plants need to live. They will learn about the importance of the...

Fifth graders examine air flow, pressure, condensation and examine how to read a weather map.  In this informative instructional activity students learn vocabulary then see how these terms can be applied by viewing a few...

A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

Spangler uses balloons and hex nuts to demonstrate centripetal force and how to make a balloon "scream." He places a nut inside a balloon before blowing it up. Then, once the balloon is tied, he begins to spin the balloon around. A force...

In this activity, learners brainstorm various ways that an uninflated balloon placed over a bottle's opening can be inflated without touching the balloon.

Students experiment with swirling sand and stone inside a bottle for this assignment. They predict what the final design will turn out to look like. Students after observing the bottle still, turn the bottle upside-down and experience...

This tutorial by Bill Nye explains how to make a simple barometer using a jar and a balloon. The barometer is an old and accurate first look at predicting the weather by examining the pressure of the atmosphere. Discover how atmospheric...

This resource provides a short experiment for students to explore how clouds are formed.

Students observe that a change in the temperature of air can impact the size of a bubble placed on a bottle that is cooled and/or heated.

Young scholars examine the earth's atmosphere. In this hands-on science lesson, students follow the outlined steps to create clouds in 2-liter bottles.
