Atomic Energy Lab Instructions: Complete all sections of this report and answer all questions in complete sentences for full credit. Title: Objective(s): Hypothesis: Choose the hypothesis that best suits this lab (delete the other one) Each emission spectrum will produce its own unique element that can be used to determine the composition of a newly discovered star. Each heated element will produce its own unique emission spectrum that can be used to determine the composition of a newly discovered star. Materials: What scientific equipment and tools were used to collect data in the simulation? (Record the materials as you work through the simulation.) Part I Materials Part II Materials Bunsen burner, barium, calcium sodium, rubidium, potassium, litum, test tubes, platinum wire, hydrochloric acid (HCI) Spectroscope, light source, hydrogen helium, neon, mercury, prisim, heat, spectrum, slit (to shine light through) Variables: Remember the three variables: controlled (what is kept the same), independent (what is tested or changed), and dependent (what is the outcome or observed). List variables below as you work through the simulation. Variable Part I Variables Part II Variables Controlled test tube, Bunsen burner, platinum wire, hydrochloric acid used to clean the platinum wire temp of flame prism, light angle light source size of prism size of slit wavelength measuring tool Unless Otherwise Noted All Content © 2022 Florida Virtual School.

Independen t Element used Element used Dependent Color of flame The light beams on the color spectrum/their wavelengths Procedure: Clear steps are in the simulation. No written procedure is needed for this virtual experience. However, it is important that you understand the experimental design of this lab for the conclusion section. Data: Record your measurements below using the correct number of significant figures. The saved results of your measurements can also be found by selecting the data table button within the virtual lab. Note: First trials have been completed as a model. You still need to go through trial 1 in the simulation. Part I: Flame Tests Element Color Description Barium Light green throughout flame Calcium Light red throughout the flame Sodium Light yellow throughout the flame Rubidium Light purple throughout the flame Potassium Light blue throughout the flame Lithium Light pink throughout the flame Unless Otherwise Noted All Content © 2022 Florida Virtual School.
