Students study an ancient bronze statue, analyze its pose, and discover how conservators remove and prevent corrosion. They learn that the bronze used to make this sculpture is an alloy of copper and tin with small amounts of other elements. They use the periodic table to research the chemical formulas of compounds used to make bronze. Students compare conservation techniques in two ancient bronze objects.

In this activity, students critically analyze prior conceptions and textbook visuals of the relative sizes and orbiting distance of the Earth-moon system (and other bodies in our solar system), search out sources for this data, and construct scale models by using balls of various sizes. There are tips for helping learners understand the large scales (i.e., millions rather than thousands) that characterize our solar system, and examples are provided of scaling using different sizes of athletic balls.

In this activity, students investigate how pressure affects the temperature of air and how this relates to the formation of clouds in the troposphere. They will form a cloud in a bottle, find the dew point and relative humidity of air at different places in the school and use a chart to estimate how high that air would have to rise to form a cloud.

In this activity, students use a National Weather Service flood forecast, USGS gauging data, and other reports to estimate the maximum storm discharge from the New River and Wolf Creek, two streams in the Southeast U.S. which experienced flooding in November 2003. Topographic and urban maps are used to predict where flooding would occur and to evaluate strategies for reducing flood risk for the residents of the region.

This is the data collection portion of a semester-long project. Before this lab, students will have graphed discharge data for one previous water year, graphed similar data collected by classes during a previous year, written one-page explanations of the techniques that they will be using, and speculated about the results they expect to get. After this lab, their data will be shared with other lab sections, which will have collected similar data at other sites along the same river. Each research group will present their preliminary data to the class during a later lab meeting, and the class will discuss how the different types of data relate to one another. The project culminates in a final paper (one per research group).

This group research project serves as the focus for our introductory Earth Systems Science classes. Each of four to six lab sections of 15-25 students collect discharge, sediment load, and water chemistry data from a different site along a local river, and compare their data to that collected in previous years and at other sites along the river. The project incorporates topographic map reading and graphing as well as collecting and analyzing data, and presenting the results in oral and written form. Labs on rocks and minerals use samples from the project area to encourage students to make connections between the solid Earth and surface processes.
Each component of the Florida River Project is described below, with a link to the activity sheet and related files.

The fluid mosaic model describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments.

This activity is a guided inquiry activity where students take simple measurements and use unit analysis to determine the thickness of a sheet of aluminum foil, the volume of an aluminum atom, and the radius of an aluminum atom.

Students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending and torsion. In this activity, students play the role of molecules in a beam that is subject to various loading schemes.

Students begin this activity by using the IPCC4, carbon diagram to distinguish natural and anthropogenic carbon. (A point that students may need to have clarified is that CO2 from natural and anthropogenic sources is the same molecule.). Students begin with Activity 1 , calculating the overall carbon transfer for a year, followed by an examination of the role of forests in the carbon cycle. This suite of activities includes 7 parts, and the selection of additional activities depends upon the discretion of the instructor and focus of the class.
