In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

In this online activity, learners can test their skills at finding constellations in the northern hemisphere's night sky.

Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.

In this activity, learners craft their own model of a comet on a stick to make it fly around the room.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.
