Learn about an important physics experiment that uses an invention that manipulates light in this interactive activity adapted from NASA.
Mini Mathilda is a digital project that was created by Alexis Matarangas-King. It shares activities from the Crucian Christmas Festival, such as the Coquito Festival, Boat Parade, Jump Up, and Christmas Spoken Here. Additionally, the subject of madras, as well as Virgin Islands foodways and characters like the moko jumbie, are explored.

An interactive simulation in which students use a model of charged objects to explain how charges interact and construct an understanding of Coulomb's Law. It is concerned with comparing ions and neutral atoms. The model allows the user to investigate the relationships between sign of charge, magnitude of charge, and distance between ions. The model illustrates the operation of three types of electroscopes. Next it visually explores how a static charge can bend the path of a moving electron, and then graphically and numerically explores Coulomb's Law. Lastly a model that illustrates polarization of charge illustrates why a charged balloon is attracted to a neutral wall. The system allows students to enter their multiple choice and written answers throughout the activity and generate a report of their responses at the end even if they are not logged into the system.
In this interactive activity adapted for grades 3–5 from Annenberg Learner’s Teaching Math Grades 6–8, use virtual Cuisenaire® Rods to represent fractions and to perform operations with fractions.
Many children may have heard of black holes and already have the understanding that they are ‘bottomless wells’. If something falls into a black hole, it is impossible for it to escape—even light cannot escape and is swallowed. The lack of light is how black holes get their name. These objects are mysterious and interesting, but they are not easy to explain. This activity will allow children to visualize, and therefore help them decompose, the concepts of space-time and gravity, which are integral to understanding these appealing objects.
