6.3 - Research Projects

Try the suggestions below, design your own, or write an essay using any of the questions throughout this unit as inspiration.

• Diffusion Chamber Simulation. In SimuLab 15, we suggested several topics for further explanation. Choose one and write an in-depth project report. If you can, explain your results by making use of the derivations offered throughout the unit. Be sure to compare your results from the simulation with your experimental results.

• Liesegang Patterns. Try the experiment with the agar gel you prepared for the Bacterial Growth experiments. You could also try the experiment in a petri dish instead of a vial. Write a report which compares your results to those obtained from the traditional experiment described in HandsOn 26.

• Drawing Comparisons and Distinctions. (a) Write a report which summarizes similarities and/or differences between the diffusion chamber and Liesegang experiments. (b) Summarize similarities and differences between the experiments in this unit with others in the previous units, for example bacterial growth or termite foraging.
