Science Area: Earth Science

Concept: 4.4 Air is found in every place that is not filled by some other material.

Materials:

Funnel

Rubber from a balloon

State Goals:

11.A.1f: Compare observations of individual and group results.

11.A.2d: Use data to produce reasonable explanations.

11.A.1a: Describe an observed event.

Safety Considerations: None.

Science Process Skills: observing, predicting, and inferring

Procedures:

Cover the wide mouth of the  funnel with a piece of

rubber from a balloon.

Suck some air from the narrow end of the funnel and

observe what happens to the rubber.

Explanation:

When you suck in the air, the rubber is pulled in. You are removing air from the inside of

the funnel by sucking in, and this is showing you that there was air inside the funnel.
