In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

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

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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

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 will imagine the challenges and opportunities of asteroid mining.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

¡En esta tira cómica, Mateo y Cientina son detectives! Ellos usan sus destrezas investigativas para identificar de dónde provinieron algunas muestras de arena.

In this collaborative storytelling activity, learners and caregivers develop a strong story about science and exploration.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

En esta actividad, los aprendices harán un terrario usando materiales simples.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.
