Conductivity - Pass the Buoy and Pepper, Please
Buoys around our coastlines are equipped with sensory devices which monitor temperature, salinity, and water pressure. Emerging earth scientists examine some of this data and relate salinity to the electrical conductivity of the surface...

Water in the Atmosphere
A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...
Curated OER
Reflection and Absorption of Light
Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of radiation for different surfaces. Students follow instructions in this guided inquiry based lab and are then asked...
