Unit Overview & Educational Goal

This 6-week integrated unit study uses Marcus’s passion for fast cars to drive deep learning across Science, Technology, Engineering, Math (STEM), English Language Arts (ELA), History, and Art. Rather than studying these subjects in isolation, Marcus will see how math calculates speed, physics makes cars aerodynamic, history shapes engineering, and writing shares these innovations with the world.

Week 1: The History of Speed (History, ELA, & Math Timeline)

Learning Objectives

• Explain how transportation changed from horses to the first gasoline-powered cars.
• Construct a chronological timeline using scaled measurements.
• Compare and contrast historical speeds using comparative language (faster, slowest, revolutionary).

Daily Breakdown & Activities

• Day 1: The Horsepower Era (History/Social Studies): Explore life before cars. Discuss how horses were the original "engines." Learn where the term "horsepower" comes from.
• Day 2: The First Racecars & Henry Ford (History/ELA): Read a short biography of Henry Ford and the assembly line. Look at photos of the 1896 Ford Quadricycle and the Model T.
• Day 3: The Land Speed Record Chase (Math/History): Research how land speed records jumped from 39 mph (1898) to 763 mph (ThrustSSC in 1997!).
• Day 4: Creating the Master Speed Timeline (Math/Art):
  • I Do (Parent/Educator): Show how to map out a timeline on a long sheet of paper, demonstrating how to use a ruler so that 10 years equals 2 inches.
  • We Do: Together, plot the year 1900 (Model T) and 1997 (ThrustSSC) on the timeline.
  • You Do (Marcus): Marcus plots at least 5 key car milestones, draws small illustrations for each, and writes a caption explaining why that car was a game-changer.
• Day 5: Week 1 Reflection & Reading (ELA): Marcus writes a short fictional story about a kid in 1908 seeing a Model T for the very first time.

Formative Assessment

The "Speed Limit" Interview: Marcus must verbally explain to a family member how travel changed between 1900 and 2000, using his timeline as a visual aid. He must correctly explain what "horsepower" means.

Week 2: Aerodynamics & The Invisible Wall of Air (Physics & Art)

Learning Objectives

• Define "aerodynamics," "drag," and "downforce" in simple terms.
• Demonstrate how different shapes interact with air resistance.
• Design and mold a low-drag car body using clay.

Daily Breakdown & Activities

• Day 1: What is Drag? (Science): Introduce the concept of air resistance.

  Talking Point: "Imagine walking through water. It pushes against you, right? Air does the exact same thing to cars, especially when they go super fast! We call this air-push 'drag.'"

• Day 2: The Paper Shape Experiment (Science Hands-On):
  • I Do: Drop a flat sheet of paper and a crumpled ball of paper at the exact same time. Show how gravity is the same, but drag slows the flat paper down.
  • We Do: Hold a flat piece of cardboard against a blowing fan, then tilt it at an angle to feel how the air lifts or pushes it.
  • You Do (Marcus): Marcus creates three different paper structures (a flat wall, a cone, and a wedge) and tests which one is pushed least by a hair dryer on a smooth table.
• Day 3: Downforce & Spoilers (Science/Engineering): Explore why race cars have wings (spoilers) on the back. Contrast airplane wings (which create lift to fly) with car wings (which push the car down so tires grip the track).
• Day 4: Clay Wind Tunnel Simulation (Art/Science): Marcus uses modeling clay to sculpt two different car bodies: one boxy (like an old truck) and one sleek and aerodynamic (like a modern hypercar).
• Day 5: Testing the Sculptures: Place the clay cars in front of a fan. Hang thin strips of tissue paper from a toothpick above the cars to visualize how smoothly the air flows over them. Marcus sketches the air paths in his Race Journal.

Formative Assessment

The Aerodynamic Challenge: Marcus looks at pictures of 3 real-world objects (a brick, a drop of water, and a bicycle helmet) and ranks them from most aerodynamic to least aerodynamic, explaining his reasoning.

Week 3: Power & Friction (Physics & Practical Math)

Learning Objectives

• Explain the relationship between friction, grip, and speed.
• Conduct a controlled experiment, record data, and calculate averages.
• Identify the four main forces acting on a moving car (Thrust, Drag, Gravity, Normal Force).

Daily Breakdown & Activities

• Day 1: The Magic of Friction (Science): Rub hands together quickly to feel the heat. Explain that friction is the "grip" between two surfaces.

  Talking Point: "Without friction, a race car's tires would just spin in place like they're on ice! But too much friction in the wrong places can slow a car down."

• Day 2: Setting up the Track (Math/Engineering): Build a simple cardboard ramp. Set up a launch point at the top of the ramp.
  • I Do: Demonstrate how to release a toy car without pushing it, to keep the test fair. Show how to use a tape measure from the bottom of the ramp to where the car stops.
  • We Do: Practice measuring the distance together in inches and centimeters. Record the first test run in the track data table.
• Day 3: The Great Surface Race (You Do - Science Lab):
  • Marcus prepares four different track surfaces at the bottom of the ramp: smooth wood, aluminum foil, sandpaper, and a towel.
  • Marcus runs 3 trials for each surface, measuring how far the car travels on each.
  • Marcus records all data in a table in his Race Journal.
• Day 4: Data Analysis (Math): Help Marcus calculate the average distance for each surface (or identify the longest/shortest runs if averages are too advanced, focusing on comparing 3-digit numbers). Create a simple bar graph of the results.
• Day 5: Tire Tread Design (Art/Design): Look at Formula 1 "slick" tires (for dry days) versus grooved wet weather tires. Marcus designs his own tread pattern on a drawing of a tire, explaining how it channels water away to keep traction.

Formative Assessment

The Safety Engineer Report: Marcus writes a short paragraph answering: "If it starts raining heavily during a race, what happens to the friction between the track and the tires? What should the driver do?"

Week 4: Math on the Track (Measurement, Estimation, & Word Problems)

Learning Objectives

• Calculate speed using the basic concept of Distance divided by Time.
• Estimate and measure weights using a kitchen scale.
• Solve car-themed multi-step word problems.

Daily Breakdown & Activities

• Day 1: Introducing Speed (Math/Science): Explain that speed is how much distance you cover in a certain amount of time. Introduce Miles Per Hour (mph).

  Talking Point: "If a cheetah runs 60 miles in one hour, its speed is 60 mph. If a Bugatti hypercar drives 250 miles in one hour, its speed is 250 mph!"

• Day 2: Weight vs. Speed (Math/Physics): Weigh different toy cars on a scale.
  • I Do: Show how to calibrate the scale to zero. Weigh a standard toy car.
  • We Do: Tape pennies to the top of a toy car to increase its weight. Weigh it again and predict if the heavier car will go faster or slower down the ramp.
  • You Do (Marcus): Marcus runs tests comparing the light car and the weighted car. He measures the time it takes to travel a 6-foot track using a stopwatch. He calculates which car has the higher velocity.
• Day 3: Fuel Math (Practical Math): Practice subtraction and multiplication through racing scenarios.

  Example Problem: "Marcus's race car uses 3 gallons of fuel for every lap. If the race is 10 laps long, how much fuel does he need? If his tank holds 40 gallons, will he make it without stopping?"

• Day 4: Track Geography & Scale (Geography/Math): Look at maps of famous tracks (like Monaco or Indianapolis). Discuss track lengths. Use a string to measure the curvy paths of the tracks on paper to compare their total distances.
• Day 5: Math Game - "The Pit Stop Challenge": A fast-paced flashcard math game. Each correct math fact solved is a "second" shaved off Marcus's simulated pit stop time. Can he get his pit stop under 15 seconds?

Formative Assessment

The Pit Boss Check-in: Present Marcus with a final 3-question math sheet featuring word problems about race cars (lap times, fuel usage, and car weights). He must solve them independently showing his work.

Week 5: Designing the Future (Creative Writing, Art, & Marketing)

Learning Objectives

• Apply aerodynamics, friction, and safety concepts to a original car design.
• Write a persuasive advertisement pitch for a newly designed vehicle.
• Create a detailed blueprint with a key and labeled components.

Daily Breakdown & Activities

• Day 1: Brainstorming the Hypercar (Art/Design): What powers Marcus's dream car? Electricity? Solar? Rocket thrusters? What safety features does it have?
• Day 2: Drafting the Blueprint (Engineering/Art):
  • I Do: Demonstrate how to draw a vehicle from a "side-view" (profile) and "top-down" view using a ruler on graph paper.
  • We Do: Decide on where the engine, safety cockpit, and aerodynamic wings should go.
  • You Do (Marcus): Marcus draws his final blueprint on a large sheet of paper. He must include at least 5 labeled parts with arrows pointing to specific innovations (e.g., "Active Spoiler," "Solar-Powered Intake").
• Day 3: The Vocabulary of Cars (ELA/Vocabulary): Learn persuasive adjectives used in car ads: sleek, lightning-fast, eco-friendly, unstoppable, innovative. Create a vocabulary word wall.
• Day 4: Writing the Advertisement (ELA - Persuasive Writing): Marcus writes a magazine advertisement script for his car.

  Prompt: "Why should a professional racer buy your car instead of a Ferrari? What makes it faster, safer, and cooler?" (Must use at least 4 vocabulary words from Day 3).

• Day 5: Logo & Branding (Art): Every great car brand has an iconic logo (like Ferrari's stallion or Lamborghini's bull). Marcus designs a custom logo and brand name for his car company.

Formative Assessment

The Pitch Meeting: Marcus presents his blueprint and reads his advertisement aloud with excitement and persuasive vocal inflection to his audience (family or peers).

Week 6: The Grand Prix Capstone (Engineering & Exhibition)

Learning Objectives

• Construct a fully functional, self-propelled balloon-powered racer.
• Troubleshoot and refine design flaws during the construction process.
• Demonstrate and explain all learned concepts (speed, friction, drag) in a final presentation.

Daily Breakdown & Activities

• Day 1: Balloon Car Physics (Engineering): Introduce Newton’s Third Law of Motion: For every action, there is an equal and opposite reaction.

  Talking Point: "When air escapes backward out of the balloon, it pushes our car forward! This is the same way real rocket ships fly."

• Day 2 & 3: The Build Phase (STEM Hands-On):
  • I Do: Show how to cut straws to act as axle casings so the wheels can spin freely. Show how to securely tape the balloon nozzle to a straw so air doesn't leak.
  • We Do: Assemble the chassis (the body) together out of cardboard or a plastic bottle. Help mount the wheel axles.
  • You Do (Marcus): Marcus attaches the wheels (bottle caps), fits the balloon propulsion system, and decorates his racer to look like his Week 5 design.
• Day 4: Track Testing & Troubleshooting: Marcus runs test trials on the kitchen floor.

  Troubleshooting Guide: If the car doesn't move, ask Marcus to diagnose: "Is there too much friction? Are the wheels stuck? Is the balloon leaking air too fast?" Marcus makes adjustments and records fixes in his journal.

• Day 5: The Grand Prix Exhibition (Final Assessment): Set up a 10-foot race track. Marcus hosts a demonstration where he launches his balloon car, times its run, and presents his complete 6-week portfolio.

Summative Assessment: The Grand Prix Exhibition & Portfolio Review

This unit is graded holistically based on Marcus’s performance in the final exhibition and the completeness of his "Race Journal." Use the following rubric to assess his learning:

Differentiation & Adaptations

For Advanced Learning (Taking the Lead Lap)

• Math Extension: Calculate actual speed in feet-per-second during the Week 3 and Week 6 experiments ($Speed = Distance \div Time$).
• Science Extension: Research the difference between internal combustion engines and electric vehicle (EV) motors. Compare their environmental impacts.
• Writing Extension: Write a fully formatted, multi-paragraph newspaper article covering the "Grand Prix" race event.

For Accommodated Learning (Support Pit-Crew)

• Fine-Motor Adaptations: If cutting bottle caps for wheels is too difficult, use pre-made toy wheels, Lego wheels, or cardboard circles.
• Writing Scaffolding: Use fill-in-the-blank frames for the persuasive advertisement in Week 5 (e.g., "The amazing ______ is the fastest car because ______! It uses ______ to zip past the competition!").
• Math Scaffolding: Focus on whole numbers and simple counting/measuring without decimals or fractions. Use a color-coded measuring tape.
