A Field View of Soil - Digging Around

(Complete Item Description)

Abstract:: The purpose of this resource is to understand that variations in landscape can affect soil properties. Students investigate variations in the soils around their school to discover that soil properties like moisture and temperature exhibit considerable variability across a single landscape. They also identify factors such as slope, shade, plants, compaction, which affect the appearance of soils and their ability to hold moisture.

Investigating evaporation

(Complete Item Description)

Abstract:: Students will investigate evaporation as a cooling process. They will witness that temperature is affected by moisture content and the process of evaporation. Next, they will explore websites related to the processes of evaporation and condensation. Students will apply gained knowledge to real-life situations, and will share their new knowledge with a person outside the classroom.

NASA KSNN How do you measure the weather?

(Complete Item Description)

Abstract:: Everyone seems to talk about the weather, and it certainly has a huge effect on our daily lives. Weather is a result of day-to-day changes in the atmosphere. Changes in temperature, wind, moisture, and pressure combine to create weather. We describe it by talking about sunshine, cloud cover, temperature, wind, and precipitation.

Precipitation Protocols

(Complete Item Description)

Abstract:: The purpose of this activity is to determine the amount of moisture input to the local environment by measuring rain and snowfall and to measure the pH of precipitation. To do so students use a rain gauge and a snowboard to measure the daily amount of precipitation. Special pH measuring techniques for precipitation are used to determine the pH of rain and melted snow. Intended outcomes are that students will understand that precipitation is measured in depth and this depth is assumed to apply to a large area, that precipitation has a pH that can vary, and that snow is an input of water to the surface just like rain and each snowfall is equivalent to some amount of rainfall. Supporting background materials for both student and teacher are included.
