Here is the step-by-step identification and explanation for each weather instrument shown on the worksheet.
1. The Top Instrument (Cups on a stick)
*
What it is: Anemometer.
*
How it is used: It has cups that catch the wind and spin around. The faster they spin, the stronger the wind is.
*
Why it helps: It tells the forecaster the
wind speed. This is important for knowing if it will be breezy, windy, or stormy.
2. The Second Instrument (Glass tube with red liquid)
*
What it is: Thermometer.
*
How it is used: It contains a liquid (usually alcohol dyed red) that expands when it gets hot and shrinks when it gets cold. You read the number next to the top of the red line.
*
Why it helps: It measures the
temperature. Forecasters use this to tell us if we need a coat or if it’s hot enough for swimming.
3. The Third Instrument (Tube catching drops)
*
What it is: Rain Gauge.
*
How it is used: It is an open container placed outside to catch rain. After it rains, you measure how high the water is inside the tube using the markings on the side.
*
Why it helps: It measures the
amount of rainfall. This helps farmers know if crops need watering and helps cities prepare for floods.
4. The Bottom Instrument (Arrows pointing in directions)
*
What it is: Wind Vane (also called a Weather Vane).
*
How it is used: It has an arrow that spins freely. The arrow points into the wind. If the arrow points North, the wind is coming from the North.
*
Why it helps: It shows the
wind direction. Knowing where the wind is coming from helps forecasters predict what kind of weather is moving toward us (for example, wind from the ocean might bring rain).
