Land and People: Cape Cod Activity 1
Students make a model aquifer to study the uniqueness of Cape Cod's ground-water system. Using the model., they determine how easily contamination spreads in the aquifer system by completing and recording three activities. Using the...

Exploring Geometric Probabilities with Buffon’s Coin Problem
Scholars create and perform experiments attempting to answer Buffon's Coin problem. They discover the relationships between geometry and probability, empirical and theoretical probabilities, and area of a circle and square.
Curated OER
Perimeters, Patterns, and Conjectures
Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...

Inner Space Cavern Cave Field Activity: Drip Rate Analysis
Students compare drip rates at several different locations throughout a cave. They observe, first hand, the heterogeneity in flow paths present in karst aquifers such as the Edwards aquifer.
Curated OER
Investigating Porosity and Permeability
Student describe porosity and permeability in sand, gravel, clay and potting soil. They experiment using different materials to discover the different porous substances and the permeability of the same substances. Students place data on...
Curated OER
Geometry in Tessellations
Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.
