In this assignment, you will research an element of your choice from the periodic table. Using reference
materials and Internet sites, you will collect information about the element. You will then present your
findings in a multimedia presentation, which should include seven slides: a title slide, a slide containing
periodic table information, a slide containing physical and chemical properties of the element, a slide
containing information on the discovery of the element, a slide containing information about the location of
the element and how it is obtained, a slide containing uses of the element, and a works cited slide.
You will collect the following information about your element:
• Periodic table information including type of element, atomic number, atomic mass,
number of protons, number of electrons, number of neutrons, period number, group
number, and group name
• Physical and chemical properties of the element
• When, where, and by whom the element was discovered
• Where the element is found and how it is obtained
• Uses for the element and/or products made from the element
• Images of the element
b) Be sure to keep a list of your references so you can cite them later.
c) Ask your teacher where you should save your presentation as you work on it. Your teacher
may also have specific guidelines about the file name you should use.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
