Product Details

Be a chemical gourmet—whip up a carbon soufflé! Your students will be amazed as they watch a yellow solid-liquid mixture turn brown, then black, expand out the top of the beaker—and solidify. The beaker becomes extremely hot and the odor of burnt sugar will fill the room. Teacher Demonstration Notes included.

Concepts: Exothermic reactions, dehydration reactions, neutralization reactions.
Time Required: 20 minutes  
Note: Perform this demonstration in a fume hood or well-ventilated lab.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
