  1. Using dialysis tubing Passive Transport Lab

  2. The Question: • You and your team wish to demonstrate through a carefully thought-out lab procedure that certain substances may or may not pass through dialysis tubing. But which substances might that be? • Dialysis tubing is thin, plastic-like material that can be tied into small bags. It has pores so small that certain larger molecules can’t pass through it.

  3. The materials: • Here’s what you have to use today: • Beakers/tape/markers • Tap water • Starch-water solution • Glucose-water solution • Iodine (tests for starch) • Diastix (tests for simple sugars) • String • Dialysis tubing • Droppers

  4. The hypothesis: • Based on what you know about cell transport, diffusion, and the materials you’ve been given today, develop a hypothesis statement that your procedure will attempt to uphold. • Remember to use the hypothesis style we’ve learned from our experimental design guide.

  5. The Procedure: • Come up with a procedure that will demonstrate how some substances may move through the dialysis tubing while some may not. This procedure should be able to validate your hypothesis. • Procedures are detailed. Some other group in another school should be able to read your procedure and reproduce the exact experiment.

  6. The Data • Create a data table that reflects data you record. • Note: This procedure may run overnight. You will have time tomorrow to collect results.

  7. Analysis: • Write an analysis paragraph that interprets what your data shows. • Explainwhy your results are what they are. • Statewhether your original hypothesis statement has been upheld or refuted. • Note: Collaborate with your partner(s). Their grade is your grade.
