Scaling Galileo's Solar System - Size of the Globes
In this activity students determine the sizes of the various planets in the solar system, scaled such that the orbit of Saturn fits on campus. The students also compare the planet sizes, given the scale, to the grain sizes of different sediment types. Students recreate spreadsheets, shown in a Powerpoint module, with formulas that answer various pieces of the overall question. This module is the second in a series of four on the Galilean Solar System, and was designed for an undergraduate class

Wireless Sensor Networks for Ecology
Field biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to "observe the unobservable" through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals -- even multiple times per second -- over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively

Terrific Tastebuds
Developed for third grade. The students will be given an introduction to tastebuds, focusing on the different types of tastebuds, what they taste, and where they are located on the tongue. They will do this by sampling four different tastes (lemon - sour, sugar - sweet, salt - salty, and tonic water - bitter) and determining which can be tasted the best in what areas of the tongue. Given a diagram that maps out the main regions of the tongue, the students will indicate which area is designated f
