Crafting Your Own Weather Instruments

Mr. C introduces a DIY experiment to build an anemometer and a barometer, tools used by meteorologists to study weather. The video provides step-by-step instructions for constructing these instruments using simple materials. The anemometer measures wind speed, while the barometer measures air pressure. Mr. C explains how to use these tools to observe weather changes and encourages viewers to experiment and learn about meteorology.

What is the primary function of an anemometer?

• To measure humidity

• To measure air pressure

• To measure wind speed

• To measure temperature

Which of the following is NOT a material needed to build the anemometer?

• A balloon

• Two straws

• Four small cups

• A pencil with an eraser

What is the purpose of coloring one of the cups on the anemometer?

• To identify the starting point for counting rotations

• To balance the anemometer

• To measure the temperature

• To make it look attractive

What should you do if you want to measure how many times the anemometer spins in 60 seconds?

• Measure the wind speed

• Use a stopwatch

• Identify one cup with a marker

• Count the number of cups

What is the first step in building the barometer?

• Cutting the neck off a balloon

• Taping a straw to the balloon

• Coloring the cup

• Filling the cup with water

What material is used to cover the cup in the barometer?

• Paper

• Balloon

• Plastic wrap

• Aluminum foil

What happens to the straw on the barometer when the air pressure outside increases?

• It raises up

• It falls off

• It stays the same

• It bends down
