Discover Why You Sink and How To Float Plus a Lesson Plan For Floating and Gliding.
How do I float and why do I sink? It's a question commonly asked by beginners learning how to swim.
Hi, Mark here. Hope all is well with you.
This week, we are talking about why we sink. Scroll down and discover the science behind floating and sinking and how it may help you understand more and even help you stay afloat when you swim. Firstly, for swimming teachers, I have a lesson plan for teaching floating and gliding.
Teach Your Pupils How To Stay Afloat.
The 'floating and gliding' lesson plan below outlines some basic exercises that can be included as part of a complete swimming lesson. This plan is taken from my best-selling book where you will find lesson plans specifically for floating and confidence building, and you will also find plans written explicitly for adults. Click here for more details.
This lesson plan is taken from 101 Swimming Lesson Plans for Swimming Teachers.
Lesson plans that:
- are adaptable to your students
- save you planning time
- ensure progress

Why Do We Sink? The Science Made Simple
First, Let's clarify one thing: Floating whilst stationary in one place and staying afloat whilst swimming are two completely different concepts.
Your ability to float is all down to your relative density. What does that mean? Take this example: a log floats and a rock sinks. The log floats because its density is low relative to the density of the water. But the rock sinks because its density is high relative to the density of the water.
How does this relate to the human body? Let's say that the log is fat and the rock is muscle. Okay, so there's more to the human body than fat and muscle. There are bones, organs, blood and stuff like that, and they all contribute to your overall density. To keep this simple, let's stick to fat and muscle.
People with a higher fat content will tend to float. Lean and muscular people will tend to sink naturally. If you naturally sink, it does not mean that you cannot swim!
Let's go back to our naturally sinking rock. Like you, it has a slightly streamlined shape, so if it's propelled across the water surface, it will remain at the surface for a short time before it sinks.
Create a streamlined shape as you propel yourself through the water; add some basic swimming technique, and you will remain at the water surface as you swim!

That's it for now.
Happy swimming!
Cheers

Welcome to this week’s edition of The Swim Teach Weekly 1–2–3. 1 LEARNING GOAL Turn to the side to breathe without lifting the head. Front crawl breathing can quickly disrupt an otherwise reasonable stroke. Swimmers often know they need to turn their head, but when the breath feels rushed, they lift forwards instead — dropping the legs, losing balance and making the next breath even harder....
