Ever wonder why a stone sinks in water? Let's make sense of it with science. If you've ever tossed a stone into a lake, you know what happens next-it sinks. Let's find out why. Key vocabulary words are density, volume, sink, float, natural force, gravity, upward force, and weight. This is a great resource to help build background knowledge for students and would work well in conjunction with a lesson/unit or reading non-fiction texts on properties of waters, oceans, physics, etc. (01:46)

Powered by the force of gravity, the world's rivers deliver about 20 billion tons of loosened rock and soil to the oceans each year. For the past 100 million years, redeposited sediment has gradually increased the size of the Mississippi River Delta. But over the past several decades, the coast of southern Louisiana has been losing rather than gaining land. These aerial views from NASA, the Lunar and Planetary Institute, and U.S. Geological Survey illustrate how river management practices and severe weather events, including Hurricane Katrina, dramatically changed the size and shape of the Louisiana coastline and the Mississippi River Delta in the 20 years between 1985 and 2005.

This interactive activity from NOVA allows you to explore the important forces of lift and drag and how they affect everything from airplanes to wind turbines. In order for an object to move through the air in a stable manner, it must balance four forces: lift, gravity, thrust, and drag. Lift and drag arise as air moves over and past an object like an airplane wing. The special shape of a wing that enables it to fly is called an airfoil. Airfoil design varies depending on the purpose of the object. Learn about the wings used on different types of planes, as well as airfoils used on helicopters, wind turbines, and even race cars.All lift and drag data for the airfoils in this interactive activity were generated using NASA's FoilSim III software, version 1.3. Data assume average cruise speed for each type of aircraft.

Gravity exerts a powerful force on all of us -- relentlessly pulling us toward Earth's surface. Everything we do, from standing up and running to getting dressed and eating breakfast, requires us to expend energy, and much of that energy goes toward our struggle against gravity. However, despite the powerful force that gravity exerts, we take it for granted precisely because of its constancy. This interactive resource from the Exploratorium gives you the opportunity to imagine how the differing gravities on other celestial bodies would affect your weight.

What is mass and where does it come from? Video explains mass, inertia mass of an object, and what causes mass. There are many things about mass which we don’t know. Mass has two definitions, one is gravity, the more massive an object is the more massive the gravity. The second is how much something doesn’t like to be pushed around. So, the higher the mass the more you have to push it. The video also gives examples to these two definitions. Video is of good quality. Video would be good for middle elementary, middle and high school students. This is an interesting video for any student studying electric charge. (08:38)

Join award winning teacher Jonathan Bergmann as he interactively teaches Astronomy: Solving the Problem of Astronomical Motion. Astronomers of antiquity did not connect gravity and astronomical motion. Galileo investigated this connection with experiments using projectiles and balls rolling down planks. Galileo put science on course to determine laws of motion and to develop the scientific method. After this introduction, the concept of gravity is explained and demonstrated. Newton's theories on the motion of the moon are also explained. (09:14)

All buildings, and tall ones in particular, are subjected to pushing and pulling from gravity, the weight of their own parts, and natural forces like wind. Unchecked, these forces can destabilize or even topple or collapse a building. This interactive activity from the Building Big Web site challenges you to make the structural fixes needed to help some big buildings avert disaster. The students may need help getting started with this site.

The stone arch is one of the simplest and most elegant structures in architecture. But if an arch is built incorrectly, gravity can quickly cause it to crash into a heap. To prevent catastrophic collapses, architects came up with several tricks to keep their arches standing, including buttresses, pointed arches, and pinnacles. In this interactive activity from NOVA, try your hand at constructing a stone arch and learn more about the physics behind it.

Wearing a helmet is all about impulse, change in momentum and the force of impact. This video illustrates why you should secure your helmet to your head. Thank you very much to Colton and Jean Johnson who said yes when I asked them if I could film myself riding my bike off their dock. Colton also said, “In my 75 years of living, that has got to be the strangest request I have ever received.” Thank you also to Chris Palmer and Larry Braak for being my on-site camera operators.

The Earth's moon reflects the light from the Sun, so it is visible at night. It also rotates at the same rate that it orbits, 29.5 days, which means that we only see one side of it. The moon has one-sixth the gravity of the Earth and no atmosphere at all. Learn more about our moon with this slide show from StudyJams. Vibrant pictures are set to music while information is written under each photo. A short, self-checking quiz is also included with this link.

In this interactive resource adapted from the University of Colorado's Physics Education Technology project, hang various masses from different springs and observe how kinetic, gravitational potential, elastic potential, and thermal energy are related. A bar graph illustrates the conservation of energy by showing how the total energy of the system remains the same while the levels for the different forms of energy vary. Options allow you to choose the stiffness and amount of friction of a spring and see how different amounts of gravity affect the system.
