Science project ideas on the importance of gases in air.

Importance to Us the Other Gases of the Air Science Project Idea

air experiment We have seen that the oxygen of the air is of very great importance to us. Mention several ways in which it is of great value and several in which it is harmful. The question naturally arises, are there other gases in the air and if so, of what importance are they to us. The first problem therefore is :

Does air contain any gas besides oxygen?

Science Project Idea Air Experiment

1) Burn a taper in air, and then in oxygen.

2) Burn in oxygen a bundle of fine iron wire, dipped in sulphur. What are the results? What is the conclusion?

iron wire experiment 3) Expose a vessel of limewater to the air. Note that a scum appears on the surface. This is an indication of the presence of carbon dioxide.
