Students describe motion by the use of adding vectors. They identify the difference between the x and y components of vector quantities. Students are given the Paper Bridge Building handout and the instructions as to where to perform...

In this space science worksheet, students answer 14 essay questions pertaining to the Earth, moon, and sun and their relationship. Prior knowledge is assumed, or this could be a pre-test.

Students study scientific names and descriptions of forces.  In this motion instructional activity students organize information into a graphic organizer then teach it to other students. 

In this geometry worksheet, 10th graders examine the special segments that occur in a triangle.  The three page worksheet contains twenty-five problems.  Answers are not included. 

Students explore the aircraft used in World War II. In this World History lesson, students read an article that describes a "flying saucer" created by the Nazi's. Upon completion of the reading, students answer questions on the article,...

A brief lesson about the inter-workings of gravity and inertia.

Investigate what keeps us grounded and who spent a lot of time studying its details. How does gravity impact plant growth?

[Free Registration/Login may be required to access all resource tools.] Identifies causes and effects of landslides and mudslides and explains how slump and creep occur.

In this activity, students will perform a series of experiments with inclined planes. They will learn that as the angle of inclination of the inclined plane approaches 90 degrees, the value of the acceleration of the cart traveling down...

Learners investigate the effects of zero gravity. The resource has students measure the change in the area of calf muscle from before and after the flight to determine if muscle loss has occurred. Some topics included are muscle loss,...

Activity investigates weight and its relationship to gravity.

Did you know the rising and falling of the sea level is caused by the gravity of the Moon and the Sun? Kids learn about ocean tides including tidal currents and types of tides on this site.

Asteroids can be single large rocks, or they can be collections of rocks loosely bound by their mutual gravity "rubble piles." The difference is important to understand, so we know how to deal with these if they head towards Earth. A...

Vasarosnamenyi Baro Eotvos Lorand, better known as Roland Eotvos or Lorand Eotvos throughout much of the world, was a Hungarian physicist who is most recognized for his extensive experimental work involving gravity, but who also made...

This study guide on gravitation covers some key vocabulary, Kepler's Laws of Planetary Motion, and orbiting bodies or satellites. Includes important equations. It is available for download with free registration.

A collection of simple experiments your students will enjoy! Each activity only requires a few household items, and will certainly spark the creativity in young scientists!

This essay from the NOVA Web site explores the impact Einstein made on physics and most everything we know about the cosmos.

This site is on the science and art of skateboard design, including equipment, tricks, glossary of terms, and a live webcast of a skateboard performance.

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back. What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing.

Animated simulation re-enacts Galileo's experiment of dropping objects off the Leaning Tower of Pisa.

Using the LEGO MINDSTORMS NXT kit, students construct experiments to measure the time it takes a free falling body to travel a specified distance. Students use the touch sensor, rotational sensor, and the NXT brick to measure the time of...

Students learn about the mechanical advantage offered by pulleys in an interactive and game-like manner. By virtue of the activity's mechatronic presentation, they learn to study a mechanical system not as a static image, but rather as a...

Students learn about contact stress and its applications in engineering. They are introduced to the concept of heavy loads, such as buildings, elephants, people and traffic, and learn how those heavy loads apply contact stress. Through...

This well-written explanation of relativity includes animations and pictures which may be helpful in understanding a tough topic.
