Cutting up Dugesia dorotocephala Experiment: Does environmental variable affect regeneration rate of the planaria? Today, set up your planaria experiment Either pH, Salinity, Temperature or Light and Dark Step 1 : Label petri dish lid with name, day, time and environmental treatment (eg. Jessica, Tuesday 11am, pH 5.5) Step 2 : Fill each quadrant halfway with environmental treatment (eg.water at pH 5.5). If you do light or temp experiment, fill up with regular pond water Step 3: Place planaria on a slide and cut planaria in half lengthwise using razor under dissecting scope. Place both head and tail of planaria in a quadrant. Make a total of 3 cut planaria (filling 3 quadrants). Place a whole planaria (uncut) in the fourth quadrant as your control. Step 4: Repeat Steps 1-3 for the other 2 environmental treatments (eg. pH 6.5 and pH 7.5).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
