Weather Experiments Kids Can Do Outside

Weather Is Science You Can Feel

Unlike lab experiments that happen in controlled conditions, weather science happens in real time, all around us. Kids can build instruments, collect data, and make predictions—just like real meteorologists.

Homemade Weather Instruments

Rain Gauge

Cut the top off a clear plastic bottle. Invert the top into the bottom. Mark measurements on the side with a ruler and permanent marker. Place it outside and record daily rainfall.

Wind Vane

Cut an arrow shape from cardboard. Pin it to a pencil eraser with a pushpin. Stick the pencil in a clay base. The arrow points into the wind. Add compass directions with a real compass.

Thermometer Shelter

Build a small louvered box (like a miniature house with slatted walls) to shield a thermometer from direct sun. This gives accurate air temperature readings, just like weather stations use.

Experiments to Try

Cloud Type Journal

Photograph the sky at the same time every day for a week. Identify cloud types: cumulus (fair weather), cirrus (change coming), stratus (steady rain possible). Compare with actual weather the next day.

Temperature Mapping

Measure temperature in five spots around your yard at the same time: sunny grass, shady grass, concrete, bare soil, under a tree. The differences teach about microclimates and heat absorption.
