Anyone can teach a kid what adrenaline is in about thirty seconds. Adrenaline — also called epinephrine — is a hormone your adrenal glands release when you’re stressed or excited, and it’s the front half of your “fight or flight” response. There. Done.

But that’s a fact about a stranger’s body. A Do lesson turns it into something true about their own.

You can find the sample activity in your preview classroom. First, your kid sits quietly for a few minutes and measures their resting heart rate — just counts their pulse, or uses a little finger clip, and writes the number down. Calm baseline.

Then they trigger a real, safe burst of adrenaline. There are a few ways in the lesson — a planned jump-scare game, a cold-water hand dip, or, the one some kids beg for and some kids would hate, monitoring their heart rate on a roller coaster. Whatever they pick, the second it’s over, they measure again.

And the number has jumped. Sometimes a lot. Now the kid is holding two numbers they generated with their own heart — and that’s when you read my explanation of what happened. Adrenaline flooded in, told the heart to speed up, opened the airways, sent blood to the big muscles, all in a couple of seconds, all without them deciding anything. A survival system doing exactly its job.

Then we bring it back down on purpose — a little box breathing — and they watch their own heart rate settle. So they don’t just feel the alarm system; they feel the off-switch too. That’s a useful skill to have on life.

And for you: everything’s in the one workbook. If an activity needs anything from around the house, you’ll know ahead of time. No lab equipment, no science degree, no messy dissection. Anything you need you can pick up at the grocery store.

And after your student tries the activity, they can go to the curated video library to watch a real adrenaline response measured live on a roller coaster. And keep your eye on what happens the second time down the hill, when the body already knows what’s coming. It reacts differently. That detail teaches an important lesson.

So — Color gets the anatomy in, Write gives the information for a decision, Do makes it personal. There’s one lesson type left: the one that turns all of it into who your kid actually becomes. That’s Apply, and tomorrow’s is all about how that helps your child.
