Choose Your Instruments

Each session, students pick from the instruments below. Most groups build 2-3 instruments depending on age and session length — enough for a real working weather station to take home.

🌡️

Thermometer

Build a working thermometer from a bottle, straw, and colored water. Watch the liquid rise and fall as the temperature changes around you.

Measures: Temperature
💨

Barometer

Stretch a balloon over a jar and attach a straw pointer. When air pressure changes, the balloon flexes and moves the needle — a real weather predictor.

Measures: Air Pressure
🌀

Anemometer

Assemble cups on straws with a pin pivot to build a spinning wind speed meter. Count the spins to measure how fast the wind is blowing.

Measures: Wind Speed
🧭

Wind Vane

Build a balanced pointer with card fins on a pin. Set it outside and it swings to show you exactly which direction the wind is coming from.

Measures: Wind Direction
🌧️

Rain Gauge

Construct a graduated container to catch and measure rainfall. Mark the scale, set it out, and record how much rain falls over days and weeks.

Measures: Precipitation
🪨

Weather Rock

The most advanced meteorological instrument known to science. If the rock is wet, it's raining. If it's swinging, it's windy. If it's white, it's snowing. If it's gone... tornado.

Measures: Everything (100% accuracy)

What Students Will Learn

  • Weather vs. Climate — What's the difference between today's weather and a pattern over time?
  • Air Pressure — Why does a barometer work? What happens to air when storms are coming?
  • Temperature — How liquids expand and contract, and why that makes a thermometer work
  • Wind — Where does wind come from? How do we measure its speed and direction?
  • Precipitation — Why do we measure rain, and what can it tell us?
  • Data Collection — Real scientists record observations over time — and now so can you
  • Engineering Design — Building instruments that actually work from everyday materials

Workshop Flow

  • Welcome & Weather Talk (10 min) — What's the weather doing right now? How do you know? What tools do meteorologists use?
  • Choose & Build (40-60 min) — Students pick their instruments and build them with guidance. Younger kids may build 2, older kids can tackle 3.
  • Test & Compare (10-15 min) — Take everything outside (or near a window) and see if the instruments actually work. Compare readings across the class.
  • Weather Rock Reveal (5 min) — The grand finale. Every scientist needs a backup system.

Age Adaptations

  • Ages 4-6 — Pre-cut materials, snap-together assembly. Rain gauge and weather rock are perfect starters. Thermometer with help.
  • Ages 7-9 — Build 2-3 instruments with some measuring and cutting. Anemometer and wind vane are great at this level.
  • Ages 10-12 — Full builds with calibration. Can tackle the barometer and discuss the science of pressure systems.

Why Schools Love This Workshop

  • Flexible by Design — Choose which instruments fit your time and age group
  • Curriculum Aligned — Connects to weather and measurement standards at every grade level
  • Real Instruments — These aren't toys — they actually measure real weather conditions
  • Take-Home Learning — Students set up their station at home and keep recording
  • Low Mess — Simple materials, easy cleanup
  • Scales Well — Works for a single class or a full grade-level rotation

Perfect For

  • Elementary Classrooms (K-5) — Pairs perfectly with weather units at any grade
  • STEM Days & Science Nights — Hands-on station that every age can do
  • Afterschool & Summer Programs — Great multi-day project: build one instrument per session
  • Scout Troops — Outdoor science meets hands-on building
