Name: _________________________________ Final grade: _____________ CONCLUSION Title: Flame Test Lab Name Group members Class name (chemistry) and teacher Date State purposes of the lab: o To observe what happens when you give electrons extra energy o To determine the color of each element’s flame o To identify unknown metals based on the color of their flame Provide background information: o What are electrons, where are they, and why are they important? o What does it mean when electrons are in their ground state? Title Bullet points Quantitativ e amounts (numbers) Paragraph form Past tense 3rd person (the chemicals were combined, the color change was observed, etc.) Paragraph 1: Restate purposes of the lab Summarize what you did in 1-3 sentences Paragraph 2: Summarize Known Substances Results State your results from data table 1 in words (During the flame test the calcium produced a red flame, etc.) Which chemicals produced the same color? What do these chemicals have in common? Predict what color flame magnesium would produce. Support your statement with evidence from the lab. o Size 12 Times New Roman or Arial Double spaced Headings in bold (intro, materials, etc.) Why do electrons go to their excited state, and what is their excited state? o What happens when elements go from their excited state to ground state? o What’s a flame test? o Why does each element produce a different colored flame? Summarize what you did (the procedure) in 1-3 sentences Honors only: include and correctly cite outside research (ex: other elements’ flame tests, connection to fireworks, info on the quantum mechanical model of the atom- MUST BE IN YOUR OWN WORDS AND YOU MUST UNDERSTAND WHAT YOU’RE WRITING!) EXAMPLES ON THE BACK OF THIS PAPER! Table 1: Known Substances o Title o Correctly formatted chemical formulas o Your data o Full and abbreviated electron configurations Table 2: Unknown Substances o Title o Your data o Your hypotheses about the identities of the substances Paragraph 3: Unknown Substances State your results from data table 2 in words (During the flame test unknown substance 1 produced an orange flame, etc.) Explain how you determined the identities of the unknown substances- USE YOUR DATA FROM TABLE 1! o You must use evidence to support your claims Paragraph 4: Identify 1 error in your experiment Explain HOW error affected data Suggest how to fix error Name at least 1 other change you would make to improve the lab and get better results 1 future question (EXAMPLE: for my next lab, I would use a larger flame and see if that affects the color of each element’s flame) DATA TABLES PROCEDURE MATERIALS INTRODUCTION FORMATTING Flame Test Lab Report Checklist TABLE 1: KNOWN SUBSTANCES Chemical Formula of Compound Metal 1.
