Question

by the end of this lab, you will see how some materials diffuse through a semipermeable membrane but others do not. the materials that you examine will differ in molecule size. some will be larger and some smaller. formulate an investigative question for this situation.

Explanation:

The situation involves materials diffusing through a semi - permeable membrane with different molecule sizes. An investigative question could focus on the relationship between molecule size and diffusion through the membrane.

Answer:

Does the size of a molecule affect its ability to diffuse through a semi - permeable membrane?
