In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

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 will see how UV light affects colors over time by making their own sunprint on construction paper.

In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.

In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.

This multi-part activity from the National Parks Service blends the science of plate tectonics with the culture and history of places with dramatic geologic landscapes.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.
