C. Force and Motion: 2. The student understands that the types of force that act on an object and the effect of that force can be described, measured, and predicted.: 6-8: The student...

SC.C.2.3.1 Add Website - Add Activity

knows that many forces (e.g., gravitational, electrical, and magnetic) act at a distance (i.e., without contact).

SC.C.2.3.2 Add Website - Add Activity

knows common contact forces.

SC.C.2.3.3 Add Website - Add Activity

knows that if more than one force acts on an object, then the forces can reinforce or cancel each other, depending on their direction and magnitude.

Activity: Toothpick "Planetary Probe Lander"

SC.C.2.3.4 Add Website - Add Activity

knows that simple machines can be used to change the direction or size of a force.

Exploring Leonardo

Describes with photos, explanation & brainteasers, simple machine operations Brainteasers provide reinforcement. Photos are excellent

SC.C.2.3.5 Add Website - Add Activity

understands that an object in motion will continue at a constant speed and in a straight line until acted upon by a force and that an object at rest will remain at rest until acted upon by a force.

Activity: Blast Off

SC.C.2.3.6 Add Website - Add Activity

explains and shows the ways in which a net force (i.e., the sum of all acting forces) can act on an object (e.g., speeding up an object traveling in the same direction as the net force, slowing down an object traveling in the direction opposite of the net force).

Basics of Space Flight

A description of Newtonian Physics with an emphasis on force and motion.

SC.C.2.3.7 Add Website - Add Activity

knows that gravity is a universal force that every mass exerts on every other mass.

Sir Isaac Newton:The Universal Law of Gravitation

This is an exciting website that begins with the historical background of Sir Isaac Newton and continues with a discussion of gravity, Law of Universal Gravitation, Kepler's Laws and its application to our solar system.

A Guide to Microgravity Science for Students of All Ages

This is a very comprehensive resource providing background information on microgravity ranging from fundamental science to applications, demonstrations and references for both teachers and students.

Exploring Gravity

As the title of this site suggests "Exploring Gravity", there are neat graphical areas in which the explorer can visualize the law of gravity. This site is well organized and contains a wealth of historical information as well.'s

With an easy-to-read screen, this site will interest budding scientists with an understandable explanation of not just how gravity works but what it is and it effect on daily activities.
