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

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

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

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

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

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

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 invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

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

In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.

In this activity, learners explore clouds and how they form.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this environmental activity (page 6 of the PDF), learners identify household products that are recyclable and explore the different types of recyclable plastics.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.
