Use the materials at your lab station to measure diffusion rates of 3 different inks. The inks (red, black and blue) have been placed on the edge of a piece of filter paper. Put water in the beaker to cover the bottom. The filter paper should be placed in the beaker so the inks are at the top. Allow the water to wick up the filter paper. Let this work for at least 5 minutes. Select the best answer, fastest to slowest.
A Black, red, blue
B Red, black, blue
C Blue, red, black
D Red, blue, black

A possible conclusion to the diffusion experiment is that the molecules in the black ink are much larger than the red and blue, so black moves much slower through the filter paper.

Use the materials in your tub to do a stomatal peel on the leaf in the snack-sized zip-lock bag. Take your sample from the backside (bottom) of the leaf. Bring your specimen into focus and move the pointer so that it points to one of the stomata and then raise your hand so the teacher can verify your work. Count the number of stomata and give that number followed by the total magnification used.
23
1
Study the leaf you have used for the stomatal peel. Select the true observation.

B The leaf has a waxy feel which allows it to float on top of water where it grows.
C The wax on the outside of the leaf helps protect the leaf from desiccation.
D The wax on the outside of the leaf helps protect the leaf from pollution and herbivores.

Use the materials at your lab station to make a wet mount of an onion cell (use some of the thin skin that lines each one of the layers of the onion). Use the blue water when making the wet mount to stain the cells slightly so you will be able to see them better under the microscope. Can you identify any organelles inside the cell? If so, include them here. Also, raise your hand so I can look at your specimen and give you credit.
25
1
Use the materials at your lab station to view the roots of the onion plant. (Light or dissecting microscope) You could try some of the blue water on the roots to stain them slightly. It may help you see them better when magnified. Identify root hairs and then raise your hand so I can check your work and give you credit for this skill.
There are several identification stations along the back south counter. Please rotate in and out in a timely manner so everyone will have an opportunity to complete this part of your final. The questions start on the east wall and goes to the west wall. You will place your answers here inside Formative.
