Directions
Now that the lab is complete, it’s time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed.
The lab report is composed of three sections:
Section I: Experimental Overview
o Provide background information.
o Include the hypothesis.
o Summarize the procedure.
Section II: Data & Analysis
o Include graphs to display trends in the data.
o Identify trends in the data.
Section III: Conclusions
o Identify if the hypothesis was supported or refuted.
o Provide logical reasoning based on data.
o Explain how the experiment could be improved.

To help you write your lab report, you will first answer the eight questions listed below based on the experiment that you have just completed. Then you will use the answers to these questions to write the lab report that you will turn into your teacher.
You can upload your completed report with the upload tool in formats such as OpenOffice.org, Microsoft Word, or PDF. Alternatively, your teacher may ask you to turn in a paper copy of your report or use a web-based writing tool.
Questions

Section I: Experimental Overview
1. What is the question that you are trying to answer?











2. What is your hypothesis for this experiment?











3. What methods are you using to test this hypothesis?
Outline the steps of the procedure in full sentences.



















Section II: Data & Analysis
4. What graphs would clearly represent the trends in your data?
Your Student Guide includes information on which graphs to construct. Each graph should have the following:
a. an appropriate title
b. appropriate labels for each axis
c. an appropriate scale for each axis
d. the correct units for the data

Complete a rough sketch of each graph.





































5. What do the data in your graphs tell you?
Explain in one or two sentences what trend the reader should observe in each of your graphs.





Section III: Conclusions
6. What do the data tell you about your hypothesis?
State how your hypothesis is either supported OR refuted by the data.









7. How do the data support your claim above?
Explain your statement above. Be sure to refer to specific pieces of data from your experiment that support your argument.

Answer:

1.    What is the purpose of the lab, the importance of the topic, and the question you are trying to answer?

Explore the process for determining the density of a solid using a laboratory procedure. The importance of the lab in the topic is to find how density of an object is and if it can sink or float and it is important to answer the question so you can also find mass and volume.

2.    What is your hypothesis (or hypotheses) for this experiment?

If the mass and volume of an object can be measured, then its density can be determined, because density equals mass over volume.

2. What is an example of fast and dramatic erosion?

What’s the role of oxygen in cellular respiration?

A.
It accepts electrons and keeps the electron transport chain running.
B.
It breaks down carbon-based sugar molecules to release energy and forms carbon dioxide.
C.
It combines with hydrogen ions in sugar molecules to release energy and form water.
D.
It supplies electrons to the electron transport chain to keep it running.

When we look at stars, we notice that some appear brighter than others. Sirius looks much brighter than Rigel, but is it really brighter? Or is Sirius much closer to Earth, giving it the appearance of being brighter? Actually, Sirius is about one hundred times closer to Earth than Rigel. If the two stars were the same distance from Earth, Rigel would appear much brighter. -We use two terms to reference the brightness of a star: absolute magnitude and apparent magnitude. Absolute magnitude is the measure of the light given off by a star, while apparent magnitude refers to the amount of light received on Earth. The color of a star indicates its temperature. Blue-white stars are very hot, while orange-red stars are relatively cool. In the early 1900's Ejnar Hertzsprung and Henry Russell noticed that the higher the temperature of a star, the greater the star’s absolute magnitude. They developed a graph that depicts this relationship called the H-R diagram. Most known stars fit into a diagonal band that runs from the upper left to the lower right of the diagram. This diagonal band is called the main sequence. About 90% of all stars are main sequence stars. Most stars are currently classified using the letters O, B, A, F, G, K, and M, where O stars are the hottest and the letter sequence indicates successively cooler stars down to the coolest M class. Betelgeuse is in the red spectral class. It is one of the largest of stars with extremely high luminosity although it has a relatively low surface temperature. How would Betelgeuse be classified?

A. Giant
B. Supergiant
C. White Dwarf
D. Main Sequence
