Bottle Balance Beam—Demonstration Kit, AP6376

Product Details

This balancing act will be a real attention getter! Students will remember the concept of the center of gravity involved in this demonstration. A large water-filled bottle and a wooden board seem to defy gravity as together they balance on the board’s edge. You have to see it to believe it! Includes detailed instructions and a reproducible student worksheet.
Concepts: Center of gravity, gravity, balance.
Time Required: 10 minutes
Note: An innovative density demonstration can also be performed using blue kerosene and mineral oil, available separately.

Performance Expectations

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.
