In this video adapted from NASA, two members of a NASA research team working to produce carbon nanotubes share some background behind this new technology, show examples of how it will be useful, and explain the various tests being performed to ensure readiness for spaceflight.
This video from NASA describes the detailed computer modeling used to predict that colliding neutron stars can produce gamma-ray bursts similar to those associated with black holes.
This interactive activity helps learners visualize the role of electrons in the formation of ionic and covalent chemical bonds. Students explore different types of chemical bonds by first viewing a single hydrogen atom in an electric field model. Next, students use sliders to change the electronegativity between two atoms -- a model to help them understand why some atoms are attracted. Finally, students experiment in making their own models: non-polar covalent, polar covalent, and ionic bonds.

This concept-building activity contains a set of sequenced simulations for investigating how atoms can be excited to give off radiation (photons). Students explore 3-dimensional models to learn about the nature of photons as "wave packets" of light, how photons are emitted, and the connection between an atom's electron configuration and how it absorbs light. Registered users are able to use free data capture tools to take snapshots, drag thumbnails, and submit responses.

This video, adapted from NASA, presents rare experimental evidence from the Fermi Gamma-ray Space Telescope supporting Einstein's prediction that space-time is smooth.
In this NASA video, scientists describe how the Extreme Ultraviolet Variability Experiment will sample and track the Sun's ultraviolet irradiance, providing a detailed time sequence of extreme ultraviolet output -- data that can provide advance warning for potentially disruptive energy bursts.
This unit includes 4 lessons where in Biology, students design a proposal or program to help the environment at a tourist location and in Math, students will calculate how tourism affects the economy.
Using inquiry-based reading, students will explore an anchor text and then develop their own essential and supporting questions to guide their research.
Over the course of the unit, students will explore a variety of texts and grow in their knowledge of the impact of tourism on the environment and the economy. They will also grow in their ability to use informational text to support their inquiry and research.
This animation adapted from Garland Science Publishing takes a close look at the DNA double helix and its individual components, describing their chemical structures and how they function together to make the DNA molecule unique.
This video from NASA explains the process by which gamma-ray flashes associated with storms produce matter/antimatter particle pairs.
This animation produced by WGBH and Digizyme, Inc. demonstrates the experimental technique used to introduce DNA plasmids inside bacterial cells, a process called bacterial transformation.
