This video segment adapted from NASA's Goddard Space Flight Center explains how hurricanes develop and why there are fewer hurricanes in the Atlantic Ocean in strong El NiŰ__ŒóíŠo years.

This video segment adapted from NASA's Goddard Space Flight Center shows how integral satellites are to everyday life and describes the different types, including orbital and geostationary.

This interactive activity from the Adler Planetarium explains the reasons for the seasons. Featured is a game in which Earth must be properly placed in its orbit in order to send Max, the host, to different parts of the world during particular seasons.

This video segment adapted from NOVA tells the tragic story of two Japanese seismologists who disagreed about the threat of earthquakes in the early twentieth century. Today, seismologists in California offer residents a probability of risk that an earthquake might occur.

In this video segment adapted from NOVA, animations are used to show how the hills around Los Angeles were formed by earthquakes at small thrust faults that extend outward from the larger San Andreas fault.

The history of earthquakes in the San Francisco Bay area is plotted on a digital map and analyzed in this video segment adapted from NOVA.

In this video segment adapted from NOVA, a geologist digs a trench along the San Andreas Fault to reveal three thousand years of earthquake history. Information from the layers of sediment may help geologists to predict earthquakes.

This video segment adapted from NOVA uses historical illustrations, photographs, and animations to explain how seismographs work, the difference between P and S waves, and the Richter scale.

The purpose of this activity is to recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and students will perform several velocity calculations. Also, students will have to design and build their lander within a pre-determined budget to help reinforce a real-world design scenario.

In this video segment from NASA, robotics researcher Ayanna Howard uses engineering to improve the intelligence of robots in space exploration.

Nursery (or Kindergarten or Preschool) students enjoy seeing the evening sky with the teacher from the playground or through a big window (indoor). This is especially relevant for students who stay for extra-hour care. During late evening hours, some students feel a little lonely waiting for their parents, but they have a wonderful natural treasure: the evening sky. By observing the evening sky with the naked eye, they will notice many colours, changing colours, the first star, the subtle colours of stars, twinkling stars, and the movement of stars. Nursery teachers who think they are not science-oriented will also gain guidance skills of introducing science to students. This activity is also useful for primary school students, especially younger-grade students.

In this adapted video segment, ZOOM guest Tommy takes us on a tour of the Florida Everglades. He describes what makes a wetland biome unique, including the soil, precipitation, and biodiversity.

This video segment adapted from NOVA tells the story of two scientists who inadvertently discovered microwave radiation that is now believed to be heat left over from the Big Bang.

In this video segment adapted from NASA, students in Matsuyama City, Japan, interview Expedition 8 Commander and NASA Science Officer Mike Foale and Flight Engineer Alexander Kaleri about life and work aboard the International Space Station.

See what it is like to walk on the Moon by viewing this collection of QuickTime images from NOVA Online. Stunning 360-degree panoramas from each of the six successful Apollo Moon landings are featured.

In this video segment adapted from Interactive NOVA, astronaut John Young experiences extreme temperatures on the Moon that are a result of the Moon's low gravity and lack of atmosphere.

This activity is an interactive “out-of-the-seat” demo that allows the students to become involved in learning about fibre optic cables by imitating the way that one basically functions. While enjoying the physicality of the demo the children will pick up basic details of light, reflection, optical properties, and applications to technology. Additionally, the activity will go into details of how fibre optics are used in astronomy technology and how it is used to improve our understanding of the universe. An emphasis should be placed on asking direct questions to the children about how these concepts can influence technology, astronomy, and our world to reinforce the concepts that they are learning about.
