Common Core Reading (CCSS):

• Informational/Nonfiction Standards R.I. 1-10 for grades 3-5

Next Generation Science Standards (NGSS):

Performance Expectations (PE): (Text supports students to reach PE)

• 3-PS2-1. Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
• 3-PS2-2. Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.
• 3-PS2-3. Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other.
• 3-PS2-4. Define a simple design problem that can be solved by applying scientific ideas about magnets.

Science and Engineering Practices (SEP): (Text supports students to reach SEP)

• Planning and carrying out investigations..
• Make observations and/or measurements to produce data.
• Asking Questions and Defining Problems

Disciplinary Core Ideas (DCI):

• PS2.A: Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object’s speed or direction of motion.
• PS2.B: Objects in contact exert forces on each other.
