Floating and Sinking
Part of: 🎬 Cotuz Originals: Science
Kids guess and test which everyday things float or sink, and learn why: things that are heavy for their size sink, and things that are light for their size float. Air inside helps too.
How it works
- Press play to start the video.
- Videos 5 minutes or longer pause once or twice for a quick check. Get it right and you're on your way. If not, you'll see a friendly explanation and the video simply keeps going. Short videos skip the checks.
- At the end there's a 4-question test. Score 60% or more to complete the lesson, and 80% or more to master it. You can always watch again and try for a higher score.
