Rainy Day? 8 STEAM Activities for Grey Summer Days

Rain is drumming against the window, and the whole day outdoors feels cancelled. Or is it? Right now, on the other side of the glass, a small science show is playing out: thousands of drops running, merging and racing down the pane. A grey summer day in Norway is not a lost day — it may be the best science day of all. Here are eight rainy-day STEAM activities for kids you can do right at the kitchen table while it pours, all using things you already have at home.

What is rainy-day STEAM?

Rainy-day STEAM is simply hands-on STEAM play that uses the rain, the water and the grey day as material. A rainy day hands you, for free, what most experiments need: moving water, sound, and something fascinating to watch outside.

Here is the part that surprises most people, and that you can investigate today: a falling raindrop is not shaped like a teardrop — it is round like a tiny ball. Surface tension pulls the water into the most compact shape there is. Only when a drop grows large does its base flatten, looking more like a hamburger bun than the tear we always draw. Watching real drops on the window and asking why they look different is a perfect window into STEAM learning.

Try it at home: 8 rainy-day STEAM activities

Ages 4–12 · You need: a glass or two, water, aluminium foil, paper, a ruler and a little imagination.

1. Raindrop race on the window (science) — Guess which of two drops reaches the bottom first.
2. Build your own rain gauge (maths) — Set a straight glass outside and measure the millimetres that fall.
3. Waterproof or not? (science) — Drop water on paper, foil, plastic and cloth; see what keeps it out.
4. Build a roof that stays dry (engineering) — Make a roof that keeps a drawn figure dry.
5. Foil boat in the sink (technology) — See how many coins a foil boat holds before it sinks.
6. Paint to the sound of rain (arts) — Listen for a minute, then paint what you heard.
7. Rainbow in a glass of water (science) — If the sun peeks out, look for the colours in the light.
8. Week-long weather diary (maths) — Mark sun, cloud or rain each day and count the rainy ones.

⚠️ An adult helps. Keep water away from sockets and small children, and wipe up spills right away.

Questions to wonder about

• Where does all the rainwater go once the rain stops?
• Why does it often smell so good outside just as the rain begins to fall?
• If you could follow one single raindrop on its whole journey, how many places would it pass through before becoming rain again?

Next time the rain sets in mid-holiday, you can smile a little. A grey day is full of drops to study, water to measure and sounds to paint.
