Bio-Cell Transport

Power Standard 3
B2.5h

Materials: Cell Transport lab (sucrose solution, dialysis tubing, iodine, droppers, beakers, graduated cylinders, labels, sharpies, sugar test strips), Cell transport ppt.

Starter: Read pages 118-119. Right the main ideas for each subheading (Diffusion and Passive Transport). Go over the starter.

Lesson: After the starter, explain that we are moving into cell transport. Ask them what organelle is involved with cell transport? (cell membrane). Remind them that we just went over the structure and function of the cell membrane which is why that leads us to how the transportation of substances across the membrane works. Explain that we are going to set up a lab today to demonstrate transport of substances across a membrane.

Get the class in 5 groups. Give each member a role to play (getting 2 beakers and washing them, Glucose reading, Iodine droppers, Sucrose solution, dialysis tubing, beaker labeling). Go through the beginning of the lab together. Show the groups where the materials are at. Have the groups read the instructions and then let them go to work on the day one section. We will continue the day 2 section tomorrow. We will move on to the cell transport ppt when all the groups are finished (lab is set up, tables are cleaned if needed, and the lab questions are answered.)
