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.
