The Laws of Science: fact-checked for parents of toddlers

We love science at Little Green House. Neuroscience is super important for how we interact with the babies and children at our childcare. And physics is absolutely everywhere.

But, as The New Yorker magazine has found, some laws of physics just don’t hold with a toddler at home.

The Conservation of Energy

Energy cannot be created or destroyed.


Do not underestimate what a toddler can destroy.


The Conservation of Mass

When matter undergoes change, its total mass stays the same.


The volume of milk in a cup doubles the instant that it’s spilled—unless the object beneath the cup is both delicate and highly permeable, in which case the milk triples.


The Law of Entropy

The amount of chaos always increases.




Newton’s First Law of Motion

A body in motion tends to stay in motion, while a body at rest tends to stay at rest.


The bodies are pretty much always in motion.


The Heisenberg Uncertainty Principle

You cannot know both the velocity and the position of a body at any given moment.


But you can be certain that the velocity is rapid and the position is ill-conceived.


Newton’s Third Law of Motion

For every action, there is an equal and opposite reaction.




The Doppler Effect

When a noise-producing body is in motion, the pitch of the noise is higher when the body is approaching than when it’s receding.


This theorem cannot be evaluated until a single noise (and body) can be isolated from the bedlam.


Le Chatelier’s Principle

When a system at Equilibrium is disturbed, it will adjust in order to achieve a new Equilibrium.


There is Pandemonium, there is Delirium, and there is Valium, but there is no such thing as Equilibrium.


The Archimedes Principle

When a body is placed in water, it is buoyed by a force equivalent to the weight of the water it displaces.


When a body is placed in water, it begins vigorously splashing until it is no longer in water.


Einstein’s Theory of General Relativity

The distortion of space and time is a phenomenon known as “gravity.”


The distortion of space and time is a phenomenon known as “parenthood.” Gravity—an inescapable pull that draws a body toward a certain spot—is a supplemental force of parenthood popularly referred to as “screen time.”
