Chapter 1First day, floating

A painted round space school with floating balconies, a classroom behind curved glass, a dome of plants and planets in the window.

On Kai’s first day at the Zero Gravity Academy, nothing stayed where it was put, including Kai.

Pencils drifted past like slow fish. Lunch boxes had straps to hold them shut. The class goldfish lived in a wobbling bubble of water.

Professor Vega clapped her hands. “Today you’ll plant a seed in a little pot and watch which way the roots grow without gravity.”

Kai pressed a seed into the soil and let go of the pot for a moment. It kept going: gently, steadily, across the classroom and out of the open door.

“In space, things keep moving until something stops them,” said Professor Vega. “You’d better go after it!”

What happens next is up to your child

How should Kai chase the pot?

Questions for grown-ups to ask

Did you spot it?

  1. EasyWhy did the plant pot float away?Answer: Everything floats at the Zero Gravity Academy, and nothing stopped the pot once it started moving.
  2. MediumWhat did Professor Vega want to find out with the seeds?Answer: Which way the roots grow without gravity.
  3. HarderIn “The bendy net”, why did swinging the net push the hero the other way?Answer: In space every push pushes you back, and there is nothing to stand on to stop you moving.

Talk about it

  • What would be the best and worst things about a school where everything floats?
  • If you could do one experiment in space, what would it be?

Words to talk about

gravity
The pull that makes things fall towards the ground.
corridor
A long passage inside a building, with rooms off it.
vent
An opening that lets air in or out.
satisfying
Pleasing, because it feels just right.

Reading it together

Lessons in Zero Gravity is written at Litsee’s reading level for age 8. Its science is real and simple: things keep moving until something stops them, every push pushes you back, and roots look for “down” even when there isn’t one.

Each part of the story has a real space fact card from the Litsee app’s fact bank, mostly from NASA and the Science Museum. One is about Helen Sharman, the first British astronaut, which is a good moment to look her up together.

Try the pushing idea on a smooth floor in socks or on a wheeled chair (with a grown-up): push off a wall gently and notice how far you go before you slow down.

Questions parents and teachers ask

Is the space science in the story accurate?

Yes, in simple form. In zero gravity, things keep moving until something stops them, every push pushes you back, and plants’ roots grow in many directions. The fact cards are quoted from the Litsee app’s fact bank.

What age is it for?

Ages 7 to 9, at Litsee’s reading level for age 8. Children who loved Picnic on the Moon often enjoy it next.

Can my child choose who the story is about?

Yes. Kai leads Lessons in Zero Gravity unless your child picks another of the 15 heroes above it. That hero’s name then fills every page, and “Put them in the pictures” paints them into the Zero Gravity Academy. Nothing is typed, saved or sent.

Now let your child make a story of their own.

In Litsee, your child creates the hero, picks the world and chooses what happens next in an illustrated story that is read aloud.
