It Won't Budge: Balloon
Eighth graders use the scientific method to discover why a balloon is not inflated.
American Statistical Association
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.

Our Class Record Book
Second graders, in groups, prepare a list of proposed record ideas for the class book.
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...
Curated OER
Triangle Explorer
Students calculate the area of triangles using a variety of materials including computer applets.

Inner Space Cavern Cave Field Activity: Drip Rate Analysis
Learners 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.
Curated OER
Rice (Gohan) Observations
Second graders investigate rice or gohan as it's called in Japan in a couple of experiments. They tally the results.
