SPREADSHEET INVESTIGATION ABOUT THIS CHALLENGE In this challenge, students will investigate the spreadsheet of math that was used in the making of “The One Moment” music video. The spreadsheet provided is the actual spreadsheet used by the band to ensure that their high-speed video would match up with the song when played in slow motion. Your students will learn about statistics, rates of change, and additional concepts relating to filming within different frame rates. CONTENT AREA Grade Levels: 9-12 Content Area: Mathematics, Algebra, Statistics Context for Learning: Before starting this lesson, students should be familiar with reading spreadsheets and have a general understanding of statistics and rates of change.

Compare analytical data and experimental data. Compare the data taken from multiple trials of a certain experiment. Calculate benchmark values/measures of central tendency for a set of data (MMMR). Organize information in an excel document. Collaboratively create videos. Understand and test how changes in time influence other data values in film making. MATERIALS Access to a device with Microsoft Excel A device that can record video EDUCATOR GUIDE | PAGE 3 www.OKGoSandbox.org INSTRUCTIONAL DELIVERY OPENING ACTIVITIES/MOTIVATION Go to OKGoSandbox.org and play the “The One Moment” music video (4 minutes and 12 seconds). Ask students how they think this video was made so precisely to match the music. Then play the “The One Moment of Math” video (4 minutes and 34 seconds). This video will explain the specific math calculations required to create OK Go’s music video “The One Moment.” Have each student pull up the One Moment of Math spreadsheet and take a few moments to sift through the pages. Have the students record a few of their first observations on the Spreadsheet Investigation Student Guide. Some Vocabulary for this Lesson: A frame is a still picture that is placed together to make a video. The number of still photos taken per second in a video is called frame rate. For example, the slow-motion frame rate is 30 frames per second, meaning there are 30 still photos taken in one second that are combined to make a video. The change in one variable in relation to another variable, such as beats per minute or frames per event is called rate of change. This is often represented by the slope on a line. Rates are different units that can be used to measure a relational change in an event (ex: seconds per minute, fingers per hand, inches per foot, frames per event).Slow motion is the action of showing film or playing back video more slowly than it was made or recorded, so that the action appears slower than in real life. One thing to remember is that slow motion is relative to the speed a video was recorded at. For example, if a slow motion video was recorded at 550 fps and played back at 30 fps, the video will be 18.3 times longer than the time it was recorded. Theoretical data is the data and numbers found using math equations that represent what would happen in a real-life experiment or event. Analytical data is data and numbers that were found when completing an experiment. EDUCATOR GUIDE | PAGE 4 www.OKGoSandbox.org PART ONE: SCAVENGER HUNT Students will now look specifically at the questions laid out on the spreadsheet On the Spreadsheet Investigation Scavenger Hunt Worksheet attached to this guide, there are several questions for your students to answer using the One Moment of Math Spreadsheet. This will give your students more time to investigate the sheets and dive deeper into the math of the moment! Students should answer the following questions in the worksheet. Answers are provided here. Look closely at the master spreadsheet page and answer the following questions: How many columns are there? How many rows? Answer: 24, 221 What is the title for column X? What is the title of/for row 193? Answer: Various worksheets, quarter notes Look at column E. This shows the frames per second (FPS) that the camera captured the images at. Now look at column F. This is the data from a simulation (EXPLAIN this term in the vocab or here). List three row numbers where the values in column E are different than the ones next to them in column F. Answer: row 2-23, 26, 27, 52, 70, 71, 192-211 The “absolute frame #” column tells us how many frames we have so far. How many frames are there at the end of the song? Answer: 6677 EDUCATOR GUIDE | PAGE 5 www.OKGoSandbox.org PART ONE: SCAVENGER HUNT CONTINUED Now navigate to the tab named “WATERMELONS.” What differences do you notice between watermelon takes one through three? Answer: general observations from students Next, navigate to the “SALT + PAINT” tab and answer the following questions: How many SALT + PAINT runs are there? Answer: 10 How many salt flowers are labeled in SALT + PAINT 6? Is this the same as the rest of the tests? Answer: 14, yes How many paint buckets are labeled in the SALT + PAINT tabs? Answer: 23 Now, click on the tab named “ORNAMENTS CRASH” and answer the following questions: In ORNAMENT CRASH TEST 4, find the column called “event time in sequence.” What are the first 5 times listed in this column? Answer: 0.053, 0.053, 0.105, 0.158, 0.211 What is the mean of these values? The mode? The range? Answer: mean = 0.116, mode = 0.053, range = 0.158 EDUCATOR GUIDE | PAGE 6 www.OKGoSandbox.org PART ONE: SCAVENGER HUNT CONTINUED Lastly, navigate to the “BALLOONS and GUITAR” tab. Are the “frame intervals between events in on-set playback” the same for the BALLOONS and GUITAR tabs? If yes, what is it? If no, what are they? Answer: No. Balloons: 7. Guitar: 15 PART TWO: CHALLENGE Students will create their own videos and use calculations to make a spreadsheet based off their video. The Spreadsheet Investigation Scavenger Hunt Worksheet attached at the end of this guide walks students through the process of collecting data from their videos and calculating to create the new, lengthened version. Students will finish the activity by comparing the analytical data to the theoretical data. After completing the scavenger hunt in part one, students will film a short video in which 5 key things happen. This could be things falling on the ground, new things appearing in the video, friends giving each other a high five, etc. Using Excel, they will record their notes and observations. Specifically, students should write down their five events, record the times at which they happen, and describe what is happening in their own words. EDUCATOR GUIDE | PAGE 7 www.OKGoSandbox.org PART TWO: CHALLENGE CONTINUED Next, students will complete some calculations based off their video and the information they’ve recorded so far. First, students will calculate the time between each key event. Next, they will find the average, or mean of these numbers. Then, guide students in finding the maximum, minimum, and mean, of the time between each key event. For their last calculation in this section, students will explore what happens if they made their video three times longer. Students should calculate what times the key events would happen if this were the case. Make sure they happen in the same order and have three times as much time between them. For example, if something happened at 2.1 seconds in the original video, it would need to happen three times later, at 6.3 seconds. These new numbers are your theoretical times, when you want your events to occur. Using the new times they calculated for the longer video, have students record their video again so that the key events happen as close as they can to these new times. Have them watch the new video again and record the actual times things happened. Explain that this is analytical data. Lastly, students should compare and contrast their analytical and theoretical data. This can be done in small groups or in a new tab on their spreadsheet.
