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

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

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

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 explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

This quiz lets you estimate your annual radiation exposure.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, learners explore sports engineering and advanced materials development.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.
