<strong>Lab</strong> 6: Diffusion<br />
3. Using a micropipette, place a single drop of blue dye in the middle of the petri dish lid. Note<br />
where the drop fell on the ruler.<br />
4. Measure the diameter of the dye (the distance it has traveled) every 10 seconds for a total of 2<br />
minutes. Record your measurements in the following tables (Tables 1, 2, and 3) and graph<br />
your results (distance traveled on the y axis, time on the x axis).<br />
5. Repeat this process using the red dye in the bottom half of the petri dish.<br />
6. After you have recorded your results, clean out the petri dish halves.<br />
7. Choose one other liquid from your cupboard and repeat steps 2‐5 using your chosen material<br />
in place of the corn syrup.<br />
8. Record your results in Table 1.<br />
