Term
Galileo
Definition
He was the first person to examine the pendulums unusual characteristics. Also discovered that each pendulum has a period. Also found that when pendulum stops swinging it stops in the middle.
Term
Conclusion
Definition
Includes 3 parts:
Summary of Findings
Possible Sources of Error
Concluding Statement
Term
Bob
Definition
The weight/mass of the pendulum. Also Allows the pendulum to move back and forth. Under the influence of gravity.
Term
Purpose
Definition
What are you trying to find out in this experiment. What are you trying to show. 2-4 sentences.
Term
Data Analysis- Graph
Definition
Pictorial view of data. Show comparisons. Choose most effective graph to display your data. All graphs must include a title. Label each axis and the units of measure. Independent variable is graphed on the horizontal axis.
Term
Procedure
Definition
Step by step instructions so that another person can repeat your experiment. Should appear as a numbered list of steps. Use metric units only. Include diagram if necessary.
Term
Data Analysis - Interpretations
Definition
Explain the meaning of your observations and numerical results. Support these with data collected. Discuss the shapes of your graph through direct comparison. Do not include through data. Data is interpreted.
Term
Leon Faucault
Definition
Known for Foucault Pendulum. Pendulum was used to measure different lengths in how many periods it could complete in 20 seconds with those different lengths.
Term
Arch
Definition
Space where pendulum swings
Term
Christiaan Hudgyens
Definition
Was first famous dutch man to create a pendulum clock. Was created in 1659. Pednulum clock has pendulum in a glass case.
Term
Materials
Definition
List all Materials needed to be perform in this experiment. Include the number or quantity of each item needed. Should be seen as a list. Use only metric units.
Term
Data Analysis - Graph
Definition
Pictorial view of data. Show comparisons. Choose the most effective graph to display your data. All graphs must include a title. Label each axis and the units of measure. Independent variable is graphed on the horizontal axis.
Term
Hypothesis
Definition
What do you think you'll find out by doing this activity. What are your predictions for this experiment. Why do you expect these results. Should be 2-5 sentences.
Term
Control
Definition
Control group does not include which variable is being tested. Serves as a standard reference to your results. 2-5 sentences.
Term
Concluding Statement
Definition
State whether your hypothesis was correct. State how you would redo your experiment to remove possible sources of error.
Term
Summary of Findings
Definition
A summary of the Data Analysis. Restate the main findings or ideas from the data interpretations. 2-5 sentences.
Term
Possible Sources of Error
Definition
Describe the factors that may have contributed to faulty results. Each factor should be set apart within its own paragraph. Length is determined by the number of errors or your list.
Term
Equation of Pendulum
Definition
T= 2 pie square root of L/G
G stands for gravity. L stands for length of pendulum. 2 pie is the circular motion of pendulum while acting with gravity.
Term
Statement of Problem
Definition
Provide background information on the topic. Discusses what is already known about your topic. If your project is preformed on previous experiment, these should be mentioned. Mathematical equations should be mentioned. 4 paragraphs at minimum.
Term
Data Analysis - Statistics
Definition
Preform any of the following analysis. Arithmetic mean. Standard deviation. Standard error. Include those in your graph.
