Lung Model

What you need

• An empty plastic bottle with the bottom cut off (adult cuts)
• 2 balloons
• 1 straw
• Tape or play dough

The Lesson

The bottom balloon works like your diaphragm. When it pulls down, your lungs fill. Slow, deep breaths calm your heart rate. Try box breathing: in 4 seconds, hold 4, out 4, hold 4. Use it at the free throw line or before a test.
