The Original

Reach the top and you're reading the real text — word for word, nothing changed.

// rung 1 of 5 — one hard sentence about volcanoes

Magma is hot, melted rock under the ground. It has gas stuck inside it, kind of like a shaken-up soda can. When magma moves up near the top, there's less stuff pushing down on it, so the gas wants to get out. If the magma is thick, the gas can't leak out slow — it blasts out fast. That fast blast is what makes a volcano explode instead of just flowing out.

// rung 2 of 5

Deep underground, hot melted rock called magma has gas trapped inside it — like a shaken soda bottle. As the magma moves up, there's less weight pushing down on it, so the gas starts to escape. If the magma is thick, the gas can't get out slowly; it bursts out fast. That's why some volcanoes explode instead of just leaking lava.

// rung 3 of 5

When magma gets close to the surface, the pressure pushing down on it gets weaker, which lets the gas trapped inside it start to bubble out. If the magma is thick and sticky, the gas can't escape smoothly — it builds up fast. That fast buildup is what makes a volcano explode instead of just oozing lava.

// rung 4 of 5

As magma rises toward the surface, the pressure holding it down drops, so the gases dissolved inside it start separating out. If the magma is too thick to let that gas escape smoothly, the gas expands faster than the pressure can be released — and the eruption explodes instead of just flowing out.

// summit — the real text

Because magma near the surface exsolves dissolved volatiles as confining pressure drops, the resulting gas expansion can outpace the melt's viscosity-limited ability to relieve that pressure, producing an explosive rather than effusive eruption.

Easier words. Never less truth.

Nothing gets cut

Every rung tells the whole story — same facts, same events, just easier words. The summit is never a shortcut; it's the original text, unchanged, word for word.

Progress is proven, not assumed

Every rung ends with a 3-question quiz before your child can climb higher. Missing more than one keeps them on that rung until they've actually got it.

Real texts, not worksheets

Paste in the actual chapter, article, or assignment your child is reading — not a generic passage picked for them. Whatever they're assigned or just curious about works the same way.

////// privacy

Your child's reading stays private.

There's no account to create and nothing to sign up for. Your child's progress saves only on this device, and we don't run ads. Nothing your child reads, and nothing they type, is ever stored on our servers.

One ladder for math, too?

We're building ReadRungs a big sibling: leveled reading plus math practice where every answer is checked by a real math engine — made first for homeschool families with kids in grades 6–12.

Who does the climbing at your house?

We keep your email only to tell you when it's ready — nothing else — and ReadRungs stays free either way.
