Semiconductors are the materials that make modern electronics work. Learn about the basic properties of intrinsic and extrinsic or 'doped' semiconductors with several visualizations. Turn a silicon crystal into an insulator or a conductor, create a depletion region between semiconductors, and explore probability waves of an electron in this interactive activity.
One of the difficult concepts for students to understand is how stacked parasequences form and what they tell us about the interaction between relative sea-level change and sediment supply. A dated but easily manipulated (and free) modeling program (Fuzzim) allows the creation of increasingly complex depositional scenarios. A single parasequence generated over one sea-level cycle demonstrates the relationship between the rate of sea-level rise and transgression/regression. By superimposing shorter sub-cycles, the model builds aggrading, prograding and retreating depositional packages. The sea-level curve, initial topography (e.g., ramps vs. more abrupt shelf margins), and sediment supply can be easily modified by the instructor or the student. Students work through basic model set-up and complete several model runs. They are encouraged to modify input conditions and explore the effects on sedimentary output. The goal is to develop an intuitive understanding of how large-scale sedimentary cycles relate to the interplay between sea level and sediment supply. In the course at Oberlin College, model output is used in conjunction with a Walther's Law exercise (will be available) and a week-end field trip where the sedimentary cycles generated by the model can be observed in outcrop. This approach integrates the use of hand samples, thin sections, and outcrop observation to provide a hands-on connection to the more abstract concepts developed by the models.

This short video and interactive assessment activity is designed to teach third graders about shortening multiplication expressions (associative property).
Build coin expressions, then exchange them for variable expressions. Simplify and evaluate expressions until you are ready to test your understanding of equivalent expressions in the game!
This short video and interactive assessment activity is designed to teach fifth graders about single-unit, multi-step problems - word problems.
The purpose of this resource is to investigate the center pixel of a homogeneous land Cover Site in order to understand that individual land areas are part of a larger land system.
The purpose of this resource is to investigate the idea that every dynamic system has energy and matter in different forms.
Algebra students need practice determining equations of lines given a pair of points, or the line parallel or perpendicular to a given line through a given point. This Demonstration, along with guiding worksheets or a teacher presentation, gives students a chance to see the relationships between these lines and points.
Soil Carbon STEM Kit. The Natural Sciences Education & Outreach Center collaborates with CSU faculty, National Parks and citizen science programs to translate their current scientific research into unique STEM experiences for students in the form of Educational Kits that can be checked out. Each kit contains just about all of the materials needed (minus common things like water and paper towels) to explore some really interesting scientific research topics.The kits are available for teachers and informal educators in Colorado to check out for a duration of a week by submitting either a local pickup form or a delivery form available at the linked website. https://www.youtube.com/watch?v=AVNHtSSSa8c This kit is provided free for educational use. This kit is available in Spanish also at the link provided. .
