For instance, there was a play-doh egg surprise with a lego doctor figure with a stethoscope. Imagine instead an egg surprise with a real stethoscope (and maybe the figure and/or say a real egg with an inked on scope). Then show kindergarten kids using stethoscopes (it's a thing). Build associations between heartbeat sounds, wrist and apex palpation, the flashing heart icon of blood pressure machines and fitness apps, ECG, hr, hr vs time graphs, and so on. Include a clip of an N-yard dash and cool down, with with heart sounds, flashing icon, and hr graph. Hr sounds for sleeping person, walking, running or climbing stairs. For resting infant, kid, adult. And for mouse, cat, small dog, big dog, human, horse, whale. It's fun to see dogs and horses anyway, but why not take the opportunity to add heart stuff and hint at scaling laws too?
The videos linked to from the article didn't seem odd choices. They seemed to have rich and fun "learning about the world" content.
