Serc: How Greenhouse Gases Absorb Heat
In this experiment students observe two model atmospheres: one with normal atmospheric composition and another with an elevated concentration of CO2. These two contained atmospheres will be exposed to light energy in a sunny window or...

Try Engineering: Series and Parallel Circuits
The core of this lesson is simple circuits and the differences between parallel and series circuit design. Students perform experiments to test the differences between the two circuit designs using low voltage light bulbs.

Science Is Fun: The Fireproof Balloon
In this experiment, two balloons are each placed over a lighted match, but the one that has had water placed inside it does not burst. Includes an explanation of why that is so.

Serc: Flame Test
In this physical science experiment, students investigate the release of energy by observing the color of light produced when salts are heated in the flame of a burner. Students will identify the metal ion of the substance by the color...
