Just Passing Through (Beginner version)
The purpose of this resource is to develop an understanding of how water flows through different soils and how it is transformed when it flows through these soils. Students time the flow of water through different soils and observe the amount of water held and also the filtering ability of the soils. They will also observe the filtering ability of soils by noting the clarity of the water before and after it passes through the soil.

Just Passing Through
The purpose of this resource is to develop an understanding of some of the relationships between soils of different types and water. Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes through the soil and observing changes to the clarity of the water and to the characteristics of the soil.

Studying the Instrument Shelter
The purpose of this activity is to discover why an instrument shelter is built the way it is. Students construct shelters that have varying properties and place them in the same location or place similar shelters in different locations and compare temperature data taken in each shelter. Students should predict what will happen for each of the different shelter designs or placements and perform the steps of student research. Intended outcomes are that students gain an understanding of GLOBE speci

Optional Barometric Pressure Protocol
The purpose of this activity is to measure air pressure. Students record atmospheric pressure using a barometer or altimeter. Intended outcomes are that students gain an understanding that barometric or altimeter pressure varies and its increase or decrease indicates an upcoming change in the weather. Students also learn that the air has weight. Supporting background materials for both student and teacher are included.

Spot-Overlay Ames Test of Potential Mutagens
This protocol represents a cost-effective modification of the Ames Test that allows students to investigate the mutagenic potential of various common substances. Potential mutagens are tested using well-characterized auxotrophic strains of Salmonella typhimurium. By analyzing the results, students determine if any of their compounds may be mutagenic. Follow-up experiments are designed to determine the dose response of these potential mutagens. Using this protocol, we have achieved reproducible r
