In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this multi-part activity learners examine non-point water pollution.

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

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

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.

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.

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 Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

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 tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners work together to interpret an "alien message." The group pretends that this is the only message from an imaginary civilization, so there is no "key" and thus no "correct" wa

In this data activity, learners will explore shipwrecks from four National Marine Sanctuaries on the West Coast of the United States.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
