General Lesson Information
 Lesson Plan ID: 34626 Title: Super Swingers Overview/Annotation: Students will construct and test pendulums with varying weights, string types, release positions, and lengths.  They will collect, graph, and analyze data to see which variables affect the speed of the pendulum in order to predict the movement of new pendulums. Then they will then use this data to solve a real-world problem and explain their thinking.This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
Associated Standards and Objectives
Content Standard(s):
 Science SC2015 (2015) Grade: 3 2 ) Investigate, measure, and communicate in a graphical format how an observed pattern of motion (e.g., a child swinging in a swing, a ball rolling back and forth in a bowl, two children teetering on a see-saw, a model vehicle rolling down a ramp of varying heights, a pendulum swinging) can be used to predict the future motion of an object. Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.3.2- Recognize patterns of motion (e.g., straight, back and forth, zigzag, fast, slow, falling, rolling); predict the motion of a common object when a force (push, pull, gravity) is applied.

Local/National Standards:

Primary Learning Objective(s):

The students will:

• graph the relationship between the length of a pendulum and the number of swings in 15 seconds.
• predict the number of swings a pendulum will make based on experimental data.
• analyze data to solve a real-world problem.

The students will control variables to determine which variables affect the outcome of an experiment.

Preparation Information
 Total Duration: Greater than 120 Minutes Materials and Resources: string (at least 3 different types, such as fishing line, yarn, rulers or rods to use as rigid pendulums, etc.)tapepencilspaper clipswashers of different sizes or penniesmeasuring tapes or rulers (one for each group of 4 students)Graphing Sheets from FOSSweb (print and copy p. 3 "Making a Swinger" for each group of 4 students; p. 5 "Swingers Picture Graph" for each student, and p. 7 "Swingers Two-Coordinate Graph" for students you plan to accelerate)grandfather clock or clock animation displayed on screenchart paper or board for recording student responsesGrandfather's Clock story from Everyday Science Mysteries (You can read this aloud to students or print student copies for use as a guided reading activity.)pendulum vocabulary sheet (can be used for teacher background and/or student use)index cards with the following lengths labeled: 17 cm, 18 cm, 25 cm, 30 cm, 38 cm, 50 cm, 70 cm, 90 cm, 120 cm Technology Resources Needed: projector and screen or interactive whiteboard for displaying presentation / images from InternetWebsites: Background/Preparation: A pendulum is a weight attached to a string or rod that can swing freely from a fixed point.  Swings, grandfather clock pendulums, and metronomes are pendulums students may encounter in their everyday lives.  While students may have seen pendulums in the past, they probably have not thought about the variables that can affect the speed of a pendulum's swing.  They will likely theorize that the weight on the end of the pendulum or the release position affect the speed of the pendulum, but after experimenting they will realize that the only variable that affects the speed is the length of the string. Once students have accepted this through experimentation, they will collect data about the number of swings a pendulum  makes as the length of the string changes.  They will then graph the data to predict the movement of pendulums not actually tested.  Finally, they will use this information answer a real-world problem.  You may want to view this FOSSweb video for additional background information about preparing pendulums.
