An earthquake is a shaking of the ground caused by the sudden release of stored energy along a fault. Think of it like snapping your fingers. You push your fingers together enough so that they don't move when you try to slide them sideways. Then suddenly, one finger slips past the other finger and...

"Some days it feels """"""""dry"""""""" and some days it feels """"""""muggy-"""""""" even though the temperature is the same. This is due to differing amounts of water vapor in the air. In this activity, you will measure relative humidity in the air using just a temperature sensor, by comparing the...

There is always some water vapor in the air. For the most part we can't see it directly, but we can measure its presence with a relative humidity sensor. In this activity, you will use a relative humidity sensor and a soda bottle to measure humidity near surfaces, such as over a leaf or above an ice...

Much of the water cycle is visible, both in the form of liquid water (oceans, rivers, lakes, and precipitation such as rain) and in the form of solid water (ice, snow, and precipitation such as falling snow or hail). However, some of the water in the water cycle is invisible because water is also...
