Understanding Weather Instruments and Their Functions

Sandra from the Ottawa Public Library introduces a video tutorial on making a barometer and a wind vane. She explains the materials needed and provides step-by-step instructions for building each tool. The barometer measures atmospheric pressure, while the wind vane indicates wind direction. Sandra encourages viewers to try these projects and track weather changes, offering a glimpse into meteorology. She concludes by inviting viewers to explore more resources on the library's website.

What inspired Sandra to create weather tools in the video?

• A science fair project

• A conversation with a meteorologist

• A summer storm video she found

• A book she read about meteorology

Which of the following is NOT needed to build a barometer?

• A glass jar

• A balloon

• A straw

• A compass

What does a barometer measure?

• Wind speed

• Temperature

• Atmospheric pressure

• Humidity

What happens to the straw on the barometer when atmospheric pressure increases?

• It moves up

• It falls off

• It moves down

• It stays the same

Which material is NOT required to build a wind vane?

• A balloon

• A straw

• A pencil

• Plasticine

What is the purpose of the arrow on the wind vane?

• To indicate wind direction

• To measure wind speed

• To predict rainfall

• To measure temperature

How should the wind vane be aligned when used outside?

• With the nearest building

• With the moon

• With the sun

• With the compass points

What is the effect of a smaller arrow on the wind vane?

• It becomes heavier

• It works better

• It stops moving

• It spins faster

What should you track to see how the barometer corresponds to the weather?

• Barometric pressure

• Humidity levels

• Temperature changes

• Wind speed
