The Moon is Earth’s closest neighbor in space - the only other member of our solar system that humans have actually visited. This video answers key questions about the Moon, like: What keeps it revolving around the Earth? Why do we see only one side of the Moon? What is the origin of the Moon? Students will learn about how the Moon has been studied throughout history-including recent lunar missions-and about its phases, eclipses and how it causes tides on Earth
The universe is incredible-but the Earth is unique! In this fun and informative program, students will learn that, despite the vastness of outer space, Earth is the only place where we know life exists. Earth explains why our planet is so special. Students will learn about the factors that allow life to flourish on Earth, including our position in the solar system, the water cycle and the composition of the planet. This program includes a visit to the real Biosphere2 in Arizona, hands-on activity Junio (4-6), Intermediate Grades (7-8)(JI)
In the 19th century when asteroids were first discovered, the continuum of sizes in the solar system was not understood, because many people thought of the solar system as a Sun orbited by nine planets. However, as observers' abilities to see smaller and smaller bodies in the solar system improves because of better instrumentation, and as scientists continue trying to catalog the number of large asteroidal bodies that someday might collide with the Earth, the solar system is viewed as a collection of objects with a whole continuum of sizes.
A complete overview of solar technologies relevant to the built environment, including solar thermal energy for heating and cooling, passive solar energy for daylighting and heating supply, and photovoltaics for electricity production.
From the new set The Solar System, Mars explores the relationship between the Sun and Mars from the point of view of a planetary scientist. This title focuses on the universal unknowns and results of space missions, examines the role of Mars as a recorder of the formation of the solar system, and encourages a more complex understanding of the many sizes and types of bodies that orbit the Sun.
