Solar Cars 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. This kit is provided free for educational use. This Kit is available in Spanish.

Sonar technology allowed scientists to produce high-resolution maps of the sea floor for the first time. This sonar demonstration uses a Human Sound Wave to image the "sea floor" in a lecture hall. In doing so, students can see two-way travel times collected and plotted in real time. Students also evaluate sources of error that can be applied to a real sonar device.

This simulation lets you see sound waves. Adjust the frequency or volume and you can see and hear how the wave changes. Move the listener around and hear what she hears.

This example engages students in a simple simulation of specialization and division of labor. All that is needed are staplers and some paper.

Explore the factors that affect a spring's motion. A spring is a resilient device that can be pressed or pulled but return to its original shape when released. Springs are commonly helical coiled metal devices. When a spring is compressed or stretched and then released, it will vibrate at a particular frequency. This frequency is called the period of the spring. Experiment by changing the spring constant (a measure of the elasticity of the coils), the mass of the weight at the end of the spring, the initial extension or compression of the spring or the friction (or damping force) exerted on the spring. Which of these factors affect the period of the spring?

This is a simulation for a beginning econometrics course that shows students how heteroskedasticity biases an estimator and why the power of a statistical text is important.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

In this simulation, you see, on the left, a picture of a box at rest on a table. You can apply a force to the box - note that you set the y-component and the x-component separately. On the right, you can see the full free-body diagram of the box. The free-body diagram shows the gravitational force exerted on the box by the Earth, the normal force exerted by the table, the force that you apply, and, if there is one, the static force of friction. Note that, on the free-body diagram, the force of gravity and the normal force have been shifted horizontally a little so they can be seen more easily. If there is a net force, that is also indicated.

A resource for learning about probability and statistics. The text is motivated by real data and is integrated with interactive features such as applets, videos, and example prompts.

The classic Stern-Gerlach Experiment shows that atoms have a property called spin. Spin is a kind of intrinsic angular momentum, which has no classical counterpart. When the z-component of the spin is measured, one always gets one of two values: spin up or spin down.

Explore the interactions between a charged balloon and a neutral wall at the atomic-level.

Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched. Is DNA more like a rope or like a spring?

In spring 2020, the world was hit by a pandemic that spread globally by March, causing universities and most of the world to move to remote means. Summer field camps, long hailed as a rite of passage in the geosciences, were cancelled throughout the US. The community moved quickly, with NAGT developing remote learning tools and arranging for sharing and collaboration between instructors and institutions. As such, UNAVCO (GETSI) and University of Northern Colorado embarked on a data collection campaign for a summer field course entitled "Geoscience Field Issues Using High-Resolution Topography to Understand Earth Surface Processes" -- originally slated for in-person teaching. The team collected GNSS data, drone imagery for use in structure from motion, and terrestrial laser scanning from a site near Greeley, Colorado on the Poudre River. In this assignment, students conduct a Structure from Motion (SfM) survey of the Sheep Draw field site. The end product is a point cloud used in additional assignments to conduct analyses.

Map the probable locations of electrons around a nucleus to understand probability distributions and the electron cloud model.

This visualization is an interactive Energy System Map, which includes short write-ups introducing students to fundamental energy system topics, paired with animated videos and deep dive resources.
