1. Fold the filter paper in half and then fold it again into quarters. Using the ruler, measure up 1.5 cm from the closed point of the paper and make a mark. Make a small hole in the bottom of the folded filter paper by cutting at the 1.5 –cm mark with the scissors. Insert the cut filter paper into the ring of the tripod ring stand to create a funnel with the small hole at the bottom. 2. Use the compass to draw a circle with a radius of 3 cm in the center of a large sheet of paper. Then draw four more concentric circles 3 cm apart, around the first circle. Number the rings 1-5, starting from the center. 3. Mark the center of the innermost circle with a large dot. Let this dot represent the nucleus of the atom. Place the ring stand so that the hole in the filter paper is exactly above the large dot, or nucleus, as shown in Figure 1.

    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.
