Description

Diffusion Starch Dialysis Tubing Lab- Biology

This Diffusion lab includes 2 pages (Can be printed back/front) where students will observe how soaking a dialysis tubing that contains starch is affected when placed inside a beaker with water.

Included is also Background information visual aids that students can refer to before, during and after the lab that will remind them about tonicity and concentration gradients.

Linked within the lab procedure is also a video students can refer to in case they need support on making their baggies.

Students will jot down and sketch their observations on their handout. They will also have 2 open-ended analysis and conclusion questions to answer and justify their response using their observations from their lab.

Student's faces will brighten up as they see the white starch baggie turn purple in a matter of minutes. Students will start asking 'Why? How does this happen?". Students will see how the Iodine diffuses from the cup to inside the baggie.
