What is DBH?
When measuring the circumference of a tree, does it matter how high you place the measuring tape? Most scholars have never considered this question, but scientists know that measurement techniques must be standardized. The 13th...

Mass Measurement
Middle schoolers explore geometry by completing a physics activity on-line. In this mass measurement lesson, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...

Symmetry in Paper Airplanes
Students explore symmetry. For this geometry and scientific inquiry lesson, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles. Students measure the plane's angles using a...

Altitude Locator
High schoolers use protractors, strings, and straws to construct a device used to determine the height of tall objects. In this applied geometry instructional activity, students use common objects to construct a tangent height guide....

From Molecules to Mole Day Do's
Students recognize methods used to define the mole. After converting various quantities to the mole, students provide a context for understanding the usefulness of scientific notation and the mole.

Properties Of Building Materials
Young scholars investigate the concept of building materials and how they are used to create different things. They focus upon the availability, cost, flexibility, and strength of different building materials. This is done by taking part...

From Where to Where?
Students find locations based upon their latitude and longitude coordinates. For this latitude and longitude lesson, students locate points on a grid and learn how to use an astrolabe.
Curated OER
Follow The Falling Meteorite
Middle schoolers investigate the supposed traveling path of a meteorite. They use sound in order to triangulate the path. The results of the experiment are written on a map to display the path of the meteorite. The culminating activity...
