Introduction
"Twice a day, the ocean rises and falls—but why? In this mission, you’ll become tidal detectives, uncovering the forces behind Earth’s tides and creating a viral science explainer!"
Hook: Show this 30-second time-lapse of the Bay of Fundy’s extreme tides. Ask: Could you surf a wave like this? What’s pushing the water?
Task
Goal: Create a 60-second TikTok-style video or interactive poster explaining tides to middle schoolers.
Requirements:
Explain the moon’s/sun’s gravitational pull and Earth’s rotation.
Include a real-world example (e.g., tides in your local beach).
Use at least 2 scientific terms (e.g., spring tide, neap tide).
Process
Step 1: Investigate
Watch: NASA’s Tides Video (5 mins).
Read: NOAA’s Tides Explained (skim sections 1–3).
Step 2: Model
Option A: Use PhET’s Tide Simulator to test how the moon’s position affects tides.
Option B: Sketch a comic strip showing high vs. low tides.
Step 3: Create
Video: Use Canva or Flipgrid (script template provided).
Poster: Use Google Slides or paper + markers (include QR codes to tide charts).
Step 4: Share
Upload to Google Classroom for peer feedback ("What’s one thing you learned from this video?").
Resources
Simulations: PhET Gravity & Orbits
Data: Tide Forecast (check your local beach).
Tools: Canva Video Maker (free for educators).

Conclusion
Reflection Questions:
What surprised you about how tides work?
How could you improve your video/poster if you had more time?
Why do tides matter for coastal communities?
Final Challenge:
"Find a tide chart for your birthday this year—will it be a good beach day?"
