🏔️ Hill and valley
A child might imagine water could climb up a slope on its own; this lesson ties water's direction to gravity, the same pull that brings everything down, so water always moves from high ground toward low ground.

- A hill or mountain is a high place, and you climb up to it.
- A valley is a low place between the heights, and you go down into it.
- Earth pulls everything downwards, water included.
- So water always flows from high to low, and never the other way by itself.
The mistake most kids make here
Thinking water can climb up a slope by itself.
Try one question
Water on a slope. Where does it run?
On a slope
- always uphill
- downhill, toward the low
- only to the sky
Answer
downhill, toward the low — Yes. Always toward the low.
How Maya teaches it
Your child tells Maya what they did in class. She teaches this topic at her desk, asks questions with tappable answers, and when the answer is wrong she explains why that answer was tempting instead of saying “try again”. She remembers what did not land and comes back to it.
Your child has it when they can: Where does water run on a slope, and why always there?
How to help at home
Pour a little water on a tilted surface at home, a cutting board propped up at an angle works fine, and watch together which way it runs: always downhill, never up.
Explain that gravity pulls everything down, not just water, which is why a ball rolls downhill and water flows downhill for the exact same reason.
Point out a hill or a valley near your home if there is one, and ask which way rainwater would run if it fell there: always toward the lower ground, never toward the peak.
A good sign they've got it: shown a slope, they can point confidently to which way water would flow, and they can explain that gravity, not the water itself, decides the direction.
Questions parents ask
- Why would my child think water could flow uphill?
- Without seeing the actual physics in action, uphill and downhill can feel arbitrary. Pouring real water on a tilted surface at home makes the downhill direction obvious and memorable.
- What's the simplest way to explain why water flows downhill?
- Gravity pulls everything toward the ground, water included, so water always moves toward the lowest point it can reach, the same way a dropped ball rolls down a slope.
- Does this apply to rivers too, not just puddles?
- Yes, exactly the same rule: a river flows from higher land toward lower land, which is why rivers start in hills or mountains and end at a sea or lake.
- How does Maya teach this?
- Maya describes water on a slope and asks which way it flows, offering real options, so the connection between gravity and direction gets practiced directly.
