In this activity you will use seeds to model mining valuable materials from rocks.
How much precipitation falls in your area? To find out, use the instructions below to create your own rain gauge. Then head outside to measure rainfall in your neighborhood.
Atmospheric scientists study weather processes, the global dynamics of climate, solar radiation and its effects, and the role of atmospheric chemistry in ozone depletion, climate change, and pollution. They observe what's going on in our atmosphere today and compare it to records from years past. To monitor the weather, atmospheric scientists use highly specialized instruments that measure rainfall, wind speed and direction, humidity, and atmospheric pressure. You can measure these at your home or school. Begin creating a weather station by building a psychrometer, also called a hygrometer, to measure the relative humidity.
