Cumulus cloud
What is the best kind of weather instrument to use to know how much rain has fallen?
Rain gauge
Which kind of extreme weather might happen during a thunderstorm?
Rainstorm and lightning
What is research?
Find out about the topic using books and/or the internet
Describe precipitation.
When water droplets in the cloud get bigger and heavier, they fall back down to the earth.
What kind of cloud produces thunderstorms?
Cumulonimbus cloud
What weather instrument would I use to measure wind speed?
Anemometer
How do you stay safe during a thunderstorm?
Stay out of the water. Go inside a sturdy building.
Which step of the scientific method is hypothesis?
Describe the process of evaporation.
When energy from the sun heats the earth's surface, water turns into vapor and rises up.
Which kind of cloud looks like a blanket?
What does a wind vane measure?
Direction of the wind
Which kind of extreme weather needs warm ocean water to form?
Hurricane
What is analysis?
Record and explain the results of your experiments.
What causes the MOST evaporation from the earth's surface?
When the sun heats up the ocean
Describe what cirrus clouds look like.
Which weather instrument measures humidity in the air?

List all six steps of the scientific method, in order.
1. Purpose (State the problem)
2. Research (Find out about the topic)
3. Hypothesis (Predict the answer)
4. Experiment (Develop a plan to test your hypothesis)
5. Analysis (Record and explain the results of your experiments)
6. Conclusion (Compare your hypothesis to your results)
What happens to water after it has become water vapor?
Water vapor rises where temperature is cooler and the vapor turns back into liquid (tiny droplets of water) which forms clouds.
Describe the difference between cumulus and cumulonimbus clouds.
Cumulus: good weather
Cumulonimbus: produce thunderstorms with heavy rain or even tornadoes.
What does a barometer measure?
Atmospheric pressure
What makes a thunderstorm happen?
