Speed Squared

About this resource

In 2016, something smaller than a grain of sand chipped a window on the International Space Station. How could a speck that tiny carry enough energy to chip tough space glass? Kinetic energy grows in step with mass — but it grows with the SQUARE of speed. In this one-week, 5-level Kinetic Energy, Mass & Speed unit for middle school science (NGSS MS-PS3-1), students investigate a real mystery, then use their evidence to crack the case.

Speed Squared is part of Science Unlocked, a series of mystery-driven lesson sets. Every set opens with a real, surprising phenomenon, builds the science one level at a time, and ends with students solving the mystery in a claim-evidence-reasoning (CER) write-up.

Topics: kinetic energy, kinetic and potential energy, claim evidence reasoning (CER), science phenomenon, review games.

What's included

• Teacher Deck (83 slides, PowerPoint). Answers are highlighted on the slides. Speaker notes tell you what to say and do, what to watch for, and how to support students or push GT students further. Prep slides and answer keys are hidden, so they skip during a slideshow.
• Interactive Student Deck (52 slides, PowerPoint + PDF). Students type in boxes, drag cards and check marks, and rate their confidence. Assign one copy per student in Google Classroom or your LMS.
• Google Slides versions of both decks. Click a button in the Google Slides Links PDF to make your own copy in Google Drive.
• Teacher Guide (23-page PDF). The standard, a week at a glance, a materials list, misconceptions to watch for, a run-of-show for every level, answer keys and sources.
• Student Printable (18-page PDF + a low-ink greyscale copy). The same tasks on paper in 12 pt type, for students without devices, sub days, or anyone who learns better with a pencil. Slide numbers match the Student Deck.
• Self-grading digital activity. SCORM 2004 and SCORM 1.2 packages for an LMS that accepts SCORM uploads, a web package, and a single HTML file that opens in any browser. Notes, sorts, matches, tables and multiple-choice items grade themselves, and students get a copy-and-paste backup of their work. A 2-page teacher quick start is included.
• Two whole-class review games that open in any browser: a Jeopardy-style game (6 categories, 30 clues) and Trashketball, where teams answer on whiteboards and then shoot for points.
• Kahoot! and Blooket import files. 48 review questions, one file per level plus an all-levels file, with a printable answer key.
• Start Here guide, HTML & SCORM how-to guide and Terms of Use, so you know which file to open first.

The 5 levels (about one 45–50 minute class each)

1. Energy on the Move. Kinetic energy depends on mass and speed. Key activities: Chipped-window mystery, Mass, Speed, or No KE sort.
2. Mass Matters. Build a graph, KE vs. mass is linear. Key activities: Plot It: rocks, Read It: real ball masses.
3. Speed Matters More. KE vs. speed is nonlinear, 2× speed leads to 4× KE. Key activities: Plot It: bike, Double Trouble, real stopping-distance graph.
4. Ramp Lab. Investigation: toy car, cup, speed = distance ÷ time. Key activities: Part A (mass), Part B (speed), graph your data.
5. Crack the Case. Stretch HS-PS3-1: KE = ½mv². Key activities: KE Calculator, Stretch CER, final chipped-window CER.

Built for real classrooms

• Every level follows the same routine: "I can" targets with a confidence check, a warm-up, copy-it notes with a word bank, hands-on practice, a checkpoint students must pass to unlock the next step, and an exit ticket. A 10-item Mini Quiz wraps up the week.
• Level 1 opens with a Power-Up on the earlier-grade ideas this standard builds on (4-PS3-1, 4-PS3-3).
• The last level includes a high school Stretch (HS-PS3-1) that every student tries and advanced students can take further.
• Hands-on lab (Ramp Lab: The Investigation). Student materials list: Toy car, 4 metal washers, masking tape; Ramp: a board on a stack of books; Paper cup with a door cut in the rim (upside down); Meter stick, stopwatch (or a phone in slow motion); Kitchen scale (grams); Goggles. Safety notes are on the slides and in the Teacher Guide.
• Support is built in: word banks, sentence starters and support notes on the slides, plus GT extensions.

Standards

• NGSS MS-PS3-1: Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object. (Kentucky 7-PS3-1 uses the same wording.)
• SEP: Analyzing and Interpreting Data · DCI: PS3.A · CCC: Scale, Proportion, and Quantity
• Stretch: HS-PS3-1
• CCSS connections: 7.RP.A.2, 8.EE.A.1, 8.F.A.3, RST.6-8.7
