Weather Station DIY Project for Kids: Build & Track Data

By Maria Gonzalez · October 1, 2026

Building a weather station teaches children about meteorology, data collection, and scientific observation — all while creating a functional instrument they can use daily. This project costs under $20 and produces months of learning.

What Your Weather Station Will Measure

Measurement	Instrument	Materials	Cost
Rainfall	Rain gauge	Plastic bottle, ruler, marker	$2
Wind direction	Wind vane	Cardboard, straw, pin, pencil	$1
Wind speed	Anemometer	Paper cups, straws, pin, pencil	$3
Temperature	Thermometer	Purchase (outdoor rated)	$8
Cloud type	Observation chart	Printed chart, clipboard	$1

Build Instructions

Rain Gauge (15 minutes)

Cut the top off a clear plastic bottle. Invert the top into the bottom as a funnel. Mark measurement lines on the side with a permanent marker (every 1/4 inch = approximately 1/4 inch of rain). Place outside in an open area, away from trees and buildings.

Wind Vane (20 minutes)

Cut a triangle and a rectangle from cardboard. Attach to opposite ends of a straw. Push a pin through the straw center into a pencil eraser. The arrow points INTO the wind. Add compass directions (N, S, E, W) at the base.

Cup Anemometer (25 minutes)

Staple 4 paper cups to the ends of 2 crossed straws. Push a pin through the center into a pencil eraser. Color one cup differently. Count rotations per minute for approximate wind speed.

Data Tracking Journal

Create a daily log with columns for: date, temperature, rainfall, wind direction, wind speed, cloud type, and observations. After 30 days, graph the data to find patterns. Questions to explore:
