Describe how fog forms
It's easy to simulate the formation of radiation fog. All you need are two bottles with a narrow enough neck that you can stick an ice cube into the mouth.
Difficulty: Middle school
Does the amount of moisture in the atmosphere vary from place to place?
Relative humidity, combined with air temperature, can be used to estimate the actual amount of moisture in the atmosphere, sometimes referred to as precipitable water. Water vapor acts as a green house gas by trapping infrared radiation reflected from the earth. This explains why desert temperatures can become much lower at night, as there is little moisture in the air to trap the heat.
Difficulty: High school
Does the level of precipitation differ in various parts of the United States?
We predicted that there would be different amounts of precipitation around the United States during a given month. Further, we felt that there would even be different amounts of precipitation in the different areas of Evanston and Skokie that we live in.
Difficulty: Middle school
Explain the different types of clouds and how they are formed
The purpose of this module is to introduce a number of cloud classifications, different types of precipitation, and the mechanisms responsible for producing them. The Clouds and Precipitation module has been organized into the following sections:
Difficulty: Middle school
How are clouds formed?
By following these steps, you will have created the conditions necessary for cloud formation: water vapor in the air, smoke particles for water to collect on, and cooling of the air by lowering the air pressure within a bottle.
Difficulty: Elementary school
How to make a tornado in a bottle
At the centre of the tornado is a spinning column of air called a vortex. Some tornadoes even have more than one vortex. This project lets you see what a tornado’s vortex looks like. So grab some supplies, and let’s give it a spin!
Difficulty: Middle school
Is the size of a tornado affected by water temperature?
The purpose of this experiment is to determine the relationship between water temperature and diameter of the tornado’s core.
Difficulty: High school
What does a barometer do? Make your own barometer to demonstrate how it can be used
What is air pressure? Did you know you can make something that will measure air pressure? You can actually do a bit of weather predicting from a simple made-at-home piece of equipment.
Difficulty: Elementary school
What is the water cycle?
Precipitation, evaporation, and transpiration are all terms that sound familiar, yet may not mean much to you. They are all part of the water cycle, a complex process that not only gives us water to drink, fish to eat, but also weather patterns that help grow our crops.
Difficulty: Middle school
Which affects evaporation the most.. air temperature, water temperature or wind speed?
This experiment will show you how factors such as temperature, wind, and surface area affect the rate of evaporation.
Difficulty: Elementary school
