About this adventure

How Water Travels Through Plants is a free interactive game that teaches children aged 6–9 how water moves from the soil, through the roots and up the stem to the leaves and flowers. It follows the Year 3 Plants unit of the UK National Curriculum, and every line is read aloud and shown as a caption.

Players travel with Dewy, a water drop, to help a drooping sunflower. They make it rain, drag drops onto root hairs that soak up water like a sponge, cut the stem to find the tiny tubes that carry water upwards, and watch what happens in a drought. In the Colour Lab they run a fair test with a white flower and a celery stick standing in coloured water.

Finally they open tiny holes in a leaf to let water escape as water vapour, then try the 8-question Plant Doctor challenge.

Questions and answers

How does water travel through a plant, in simple words?

Water goes from the soil into the roots, then up the stem through tiny tubes to the leaves and flowers. Root hairs soak the water up, and water escapes from tiny holes in the leaves as water vapour, which helps pull more water up behind it.

Why does a white flower change colour in coloured water?

A white flower changes colour because the coloured water travels up tiny tubes in its stem to the petals. The change takes hours rather than seconds, and cutting a celery stick that stood in coloured water shows a ring of coloured dots where those tubes are.

Why do plants wilt when they don't get enough water?

Plants wilt because the water inside them helps keep them firm, so when the soil dries out and no water comes up the stem, the leaves and flowers droop. Watering the soil near the roots usually helps the plant stand tall again.

What age is this plants and water game for?

The game is designed for children aged about 6 to 9 and matches the Year 3 Plants unit of the UK National Curriculum for KS2 science. Every instruction is spoken aloud with captions, so children who are still building their reading confidence can follow along.

What does the game include and how long does it take to play?

The game has four chapters, an 8-question Plant Doctor challenge, and an animated intro and finale. Playing everything takes about 30 minutes. Children can start any chapter from the garden map and go back to the map at any time.
