This lab activity is designed to have students use their knowledge of balancing and identifying chemcial reactions and apply it in a fun and interesting way!

This lesson is a presentation of famous scientist throughout history where the students will learn and take notes about the contributions and discoveries made in science.

This activity is an observation lab where students observe the colors emitted by various metal ions in salt solutions.

This is a classroom lab where students will explore the concept of density by investigating how various solids and liquids interact.

In this video segment adapted from NOVA, scientists investigate how farming along the Mississippi River impacts floods and what can be done about it.

This activity is a guided inquiry activity where students take simple measurements and use unit analysis to determine the thickness of a sheet of aluminum foil, the volume of an aluminum atom, and the radius of an aluminum atom.

In this lesson designed to enhance literacy skills, students learn how the forces of gravity and air resistance affect the motion of falling objects.

Students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending and torsion. In this activity, students play the role of molecules in a beam that is subject to various loading schemes.

This media-rich essay from NOVA Online describes the challenges of forecasting volcanic eruptions and includes information about specific cases.

This activity is an extension where students freeze a liquid, making ice cream.

In this interactive activity adapted from the University of Utah's ASPIRE Lab, investigate frequency in terms of trampoline jumps, pendulum swings, and electromagnetic waves.

In this video segment adapted from NOVA scienceNOW, hydrogen fuel cell cars promise pollution-free driving, but will we see them anytime soon?

In this video segment adapted from FETCH!, contestants are challenged to use materials from a garbage dump to build a boat that floats, can be steered, and is propelled by something other than oars.

Just after World War II, nuclear scientists turned their attention from fission to fusion. This video segment adapted from AMERICAN EXPERIENCE looks at the beginnings of thermonuclear power generation.

This video segment adapted from NOVA shows how Galileo, using his newly developed refracting telescope, observed four of Jupiter's moons, the first astronomical bodies to be discovered since ancient times.

Einstein called Galileo the "father of modern physics." This media-rich essay from the NOVA Web site looks at Galileo's quest to understand the mathematics of motion.

In the early 1600s, most people believed that the Sun revolved around a stationary Earth. This video segment adapted from NOVA tells how Galileo proved that the Sun, not Earth, is at the center of our universe.

This video segment adapted from NOVA shows how Galileo used his telescope to carefully observe and study sunspots.

Scientists don't always get it right. This video segment adapted from NOVA looks at Galileo's failed theory for the motion of the tides.

This video from NASA describes the GLAST satellite, which is equipped with a gamma-ray telescope, and shares some background about the kinds of extreme universal phenomena indicated by the presence of gamma rays.
