In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

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

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners explore how salt water freezes in comparison to fresh water.

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

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners use whale count data from the Hawaiian Islands Humpback Whale National Marine Sanctuary to compare whale counts in relation to environmental factors.

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

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

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners model erosion using a clear shoebox and sand or soil.
