How can people control a hot air balloon? The simple simulation allows scholars to adjust the payload mass, burner, and vent position on a hot air balloon and observe the changes in velocity and altitude over time. Challenge questions...

Cut it in half with a compass and straightedge! Using construction tools, a video shows how to create an angle bisector. The presenter points out what it means to bisect an angle in terms of the measure and distances from the sides of...

Split it down the middle. Using the tools of geometric construction, the video shows two different methods of constructing a 30-degree angle. The first method bisects an angle of an equilateral triangle. The second uses the diagonal of a...

Figure out what to do when there is no grid to count. Using a ruler and a sharp pencil, the narrator shows how to perform a dilation when the figure is not on a grid. The ray method works by drawing a ray from the center of dilation...

Creating a 60-degree angle also creates an equilateral triangle. By watching the video, individuals learn the steps required to construct a 60-degree angle. The presentation shows that the process is the same for constructing an...

Experimentally, come up with a study design. Learners hear about different types of study designs, observational studies, and experiments. They identify the subjects, response variable, treatment, and whether there was a cause and...

Here is an activity that blends genetic technology, literacy skills, and critical thinking. Pupils review background information about cell lines and CRISPR by video and teacher-led discussion. Scholars collaborate to analyze two...

Some words are best left unspoken.  Words matter, according to Benjamin Zander, conductor, teacher, and lecturer. To illustrate his point, Zander recounts a story told to him by a survivor of Auschwitz. As a result of her experience...

Your learners will dance in their seats as this talented drummer connects math to music in a short video clip. Clayton Cameron shows how math puts the "cool" in various genres of music, including jazz, hip-hop, pop,...

Find out the science behind ancestry testing! Investigators watch a video exploring how ancestry works before participating in a hands-on group activity. Scholars role play scientists while learning about testing protocols and test...
