Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this activity (on page 134 of the PDF), learners explore reaction time.

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

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

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

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

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 activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity (on pages 2-8), learners experience how scientists use classification in their study of animals.

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

In this multi-faceted game (on pages 25-35), learners recreate what happens to creatures in the Brazilian rain forest as they grow from egg to adult—especially those that use fallen, empty Brazil nut

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.
