Hands on Weather: Weather Experiments

The video tutorial explores basic weather principles through hands-on experiments. It covers creating a tornado in a bottle, demonstrating air weight with balloons, and making a barometer. It explains how warm air rises and cool air sinks, the concept of dew point, and how condensation forms. The tutorial also includes cloud formation in a bottle and light scattering demonstrations. The video concludes with a review of key weather concepts, emphasizing the importance of understanding weather through practical experiments.

What is the first step in creating a tornado in a bottle?

• Fill both bottles with water

• Attach the bottles with duct tape

• Punch a hole in the tape

• Spin the bottles

How can you demonstrate that air has weight?

• By using a barometer

• By using a thermometer

• By using a hygrometer

• By using a compass

What happens to warm air compared to cool air?

• Both warm and cool air rise

• Warm air sinks while cool air rises

• Both warm and cool air sink

• Warm air rises while cool air sinks

What happens to air when it is compressed?

• It becomes lighter

• It stays the same

• It cools down

• It warms up

What does the dew point temperature indicate?

• The wind speed

• The air pressure

• The amount of moisture in the air

• The amount of sunlight

What is necessary for cloud droplets to start forming?

• High temperature

• Condensation nuclei

• Low humidity

• Strong winds

How many colors make up white light?

• 7

• 8

• 6

• 5

What is the role of condensation nuclei in cloud formation?

• They increase temperature

• They provide a surface for moisture to condense

• They decrease air pressure

• They absorb sunlight

What is the effect of adding milk to water in the light scattering experiment?

• It makes the water clear

• It scatters different colors of light

• It absorbs all light

• It reflects light

What is the main reason the sun appears red or orange when it is low in the sky?

• The sun is further from the Earth

• The sun is cooler

• The sun is closer to the Earth

• Light passes through more air, scattering shorter wavelengths
