A student is learning about pendulums. She decides to test to see which variable will affect the frequency of the pendulum. She sets up her pendulum and decides to change the string length and the amplitude of the pendulum. When collecting data, she notices that the frequency of the pendulum does change. Scientifically speaking, what was the cause of the change in frequency?

Mrs. Papen has two pieces of paper. To start both pieces of paper are the same size and same mass. She crumples one piece of paper into a tight, small ball. Explain in scientific terms what has changed in one piece of paper and what has stayed the same in both pieces of paper.

What is the variable in the data table? String LengthFrequency 75 cm15 cycles/ minute 60 cm25 cycles/minute 45 cm 35 cycles/minute

What string length resulted in the highest frequency? String LengthFrequency 75 cm15 cycles/ minute 60 cm25 cycles/minute 45 cm 35 cycles/minute

Based on the information on the graph, what can you conclude about the experiment?

What is the title of the line graph?

Based on the line graph what is the string length at an average frequency of 10cycles/ 30 seconds?

Based on the line graph what is the average frequency at a string length of 20cm?
