In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity, learners discover how NASA engineers develop experimental aircraft.

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.

In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

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

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

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

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
