Strand 3.3: FORCE AFFECTS MOTION

Forces act on objects and have both a strength and a direction. An object at rest typically has multiple forces acting on it, but they are balanced, resulting in a zero net force on the object. Forces that are unbalanced can cause changes in an object's speed or direction of motion. The patterns of an object's motion in various situations can be observed, measured, and used to predict future motion. Forces are exerted when objects come in contact with each other; however, some forces can act on objects that are not in contact. The gravitational force of Earth, acting on an object near Earth's surface, pulls that object toward the planet's center. Electric and magnetic forces between a pair of objects can act at a distance. The strength of these non-contact forces depends on the properties of the objects and the distance between the objects.

Standard 3.3.3

Construct an explanation that the gravitational force exerted by Earth causes objects to be directed downward, toward the center of the spherical Earth. Emphasize that "downward" is a local description depending on one's position on Earth. (PS2.B)

• 3rd Grade Rollercoasters Lesson Plan & Resources
  Phenomenon-based, 5E lessons that align to the SEEd standards. Lesson folders include lesson plans, a slideshow, and supporting materials for teaching the lesson to your students.
• Creating a Mini Golf Course
  Students will engage with one another to design, create, and build a mini golf course hole using recycled materials.  Once completed, the students will need to explain how their hole works using scientific terminolgy such as force and gravity.  This hands-on, fun, creative activity will serve as an assessment tool on what students understand about the concept of force and gravity.
• The Eye Juggler Coyote
  This lesson utilizes the Ute Indian Tribe of the Uintah and Ouray Reservation (UIT) tale, ?The Eye Juggler Coyote? to enhance comprehension skills, provide an introduction to how force affects motion and give information about the UIT. The students will read the tale and then use the story to learn about gravity and balanced forces. The connection of the Ute people to the bison will also be explored. The Ute people tell stories about Coyote and other animals to their children. Based on Coyote?s mistakes, the elders teach children about proper behavior and positive attitudes. The lessons learned help them avoid making the same mistakes Coyote made and suffering the consequences in their own lives.
• What is Gravity?
  A lesson where students explore the effects of gravity (Better Lesson). This is part of unit on motion. Lessons 6 and 7 deal with gravity.
