Serial Dilution Demonstration Model

By: The Flinn Staff

Item #: AP7515

Price: $55.70

In Stock.

The Serial Dilution Demonstration Model builds on the concepts of concentration and serial dilution. An activity model simulates the process of serial dilution as a stock “solution” of yellow beads is diluted with a blue bead “solvent.”

Product Details

What does one part per thousand look like? Make the concepts of concentration and serial dilution more concrete for your students. Unique activity model simulates the process of serial dilution as a stock “solution” of yellow beads is diluted with a blue bead “solvent.” Students will gain a better understanding of the concept of dilution as 1/10, 1/100, 1/1000, 1/10,000 and 1/100,000 simulated solutions are prepared. The beads from each dilution step are prominently displayed in durable demonstration tubes placed in a transparent display rack. Kit includes enough beads to repeat the activity at least 25 times, 5 demonstration tubes and caps, durable demonstration rack and detailed instructions.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
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.
