Heavy Yet Floating

by Anonymous · 1 · 🍴 0

🛟 Two objects weigh the same, but one sinks and the other floats. Why? Change their volume and read the buoyancy numbers to find out—the floating one isn’t simply “lighter.” 📏 Put the same object in fresh water and very salty water. In salt water, only half of it sinks. That’s why people float in photos from the Dead Sea. 🚢 Here’s the big question: a heavy lump of iron sinks, so how can a much heavier iron ship float? Keep the amount of iron the same and change only its shape. Then see what happens as you keep loading it. This app was made with code too · Shall we remix it and add a submarine?

About this app

Heavy Things Float Too is an interactive middle school science app about buoyancy and Archimedes’ principle. Choose an object’s volume and weight to compare upward buoyant force with weight, then explore how plain and very salty water change the submerged volume. A ship section shows how reshaping the same amount of iron into a bowl or ship can make it float, and how added cargo can make it sink.

Use cases

  • Middle school students learning about buoyancy and density
  • Teachers demonstrating Archimedes’ principle in class
  • Parents guiding hands-on physics exploration at home
  • Learners comparing floating, sinking, and partially submerged objects

Features

  • Three interactive sections for floating, liquid depth, and ships
  • Selectable object volumes, weights, liquids, shapes, and cargo loads
  • Numerical displays for buoyant force, submerged volume, and total weight
  • Mission-based challenges with progress tracking and explanations
  • Visual SVG scenes showing floating and sinking outcomes
  • Reset and next-mission controls with optional sound toggle
