Seasons: Why do we have them?
Learn why the temperature in the summertime is higher than it is in the winter by studying the amount of light striking the Earth. … Experiment with a plate detector to measure the amount of light striking the plate as the angle of the plate is adjusted (and then use a group of plates placed at different DemoUrls on the Earth) and measure the incoming radiation on each plate.

Seasons: Earth, Moon, and Sun
Observe the motions of the Earth, Moon and Sun in three dimensions to explain Sunrise and Sunset, and to see how we define a day, a month, … and a year. Compare times of Sunrise and Sunset for different dates and DemoUrls. Relate shadows to the position of the Sun in the sky, and relate shadows to compass directions.

Seasons in 3D
Gain an understanding of the causes of seasons by observing the Earth as it orbits the Sun in three dimensions. Create graphs of … solar intensity and day length, and use collected data to describe and explain seasonal changes.
-
Seasons Around the World
Use a three dimensional view of the Earth, Moon and Sun to explore seasonal changes at a variety of DemoUrls. Strengthen your knowledge … of global climate patterns by comparing solar energy input at the Poles to the Equator. Manipulate Earth’s axis to increase or diminish seasonal changes.

Greenhouse Effect
Within this simulated region of land, daytime's rising temperature and the falling temperature at night can be measured, along with heat … flow in and out of the system. The level of greenhouse gases present in the atmosphere at any given time can be adjusted, allowing the long-term effects to be investigated.

Weather Maps
Learn about standard symbols used in meteorology to construct weather maps. Rain, sleet, snow, temperature, cloud cover, wind speed … and direction, and atmospheric pressure can all be recorded at two different weather stations on a map.
-
Coastal Winds and Clouds
Learn about atmospheric conditions near a coast using basic observables: wind and temperature. Measure daily temperatures over both land … and water near a coastline, along with the wind speed and direction. The conditions can be recorded at a variety of altitudes.
-
Hurricane Motion
Use data from up to three weather stations to predict the motion of a hurricane. The wind speed, wind direction, cloud cover and air … pressure are provided for each station using standard weather symbols.
-
Relative Humidity
Measure the temperature on both a wet and dry bulb thermometer to determine the relative humidity over time. The two thermometers show … the temperatures as time passes on a clock, and the temperature of a bucket of water can be adjusted to learn about the dew point, condensation, and saturated air.
-
Freezing Point of Salt Water
Control the temperature of a beaker of water. As the temperature drops below the freezing point, a transformation of state will occur that … can be viewed on a molecular level. Salt can be added to the water to see its effect on the freezing point of water.
