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

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 investigate the different salinity levels of oceans, rivers and estuaries.

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

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

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

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.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

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

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

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.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
