Product Details

How big is a million? What does it mean for a contaminant to be found in a concentration of one part per million? These amazing bottles make molecular concentration and ppm contamination concepts more concrete for your students and offer many wonderful teaching opportunities.

The Becker Bottle “One in a Million Too” (AP4854) is a must purchase to go with your original Becker Bottle (AP4559). If you do not have the original Becker Bottle, order the set of two (AP4863) and save!

Concepts: Solution concentration, parts per million.
Time Required: 20 minutes
Materials Provided: Becker bottles and instructions.

Performance Expectations

MS-ESS1-3. Analyze and interpret data to determine scale properties of objects in the solar system.
MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
MS-ESS3-4. Construct an argument supported by evidence for how increases in human population and percapita consumption of natural resources impact Earth’s systems.
MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
MS-ESS2-5. Collect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions.
HS-ESS2-5. Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes.
HS-ESS3-1. Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity.
HS-ESS2-6. Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere.
