Unit 2 Forces Acting at a Distance

  • This unit has two Power Standards.

    The first Power Standard for this unit is the Next Generation Science Standard MS PS 2-5 which states that students will be able to conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

    The rubric for this standard is as follows:

    If your child achieves a level 1, she/he is considered not proficient for this Power Standard.  However, it means that the student can identify fields that act at a distance.

    If your child achieves a level 2, she/he is considered partially proficient for this Power Standard.  However, it means that the student can conduct an investigation showing that fields exist between objects exerting forces on each other even though the objects are not in contact.

    If your child achieves a level 3, she/he is considered proficient for this Power Standard, such that the student can provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

    If your child achieves a level 4, she/he is considered advanced for this Power Standard, because the student can evaluate the design of an investigation and make suggestions for improvement.

     

    The second Power Standard for this unit is the Next Generation Science Standard MS PS 2-4 which states that students will be able to construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

    The rubric for this standard is as follows:

    If your child achieves a level 1, she/he is considered not proficient for this Power Standard.  However, it means that the student can state that gravitational interactions are attractive and depend on the masses of interacting objects.

    If your child achieves a level 2, she/he is considered partially proficient for this Power Standard.  However, it means that the student can present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

    If your child achieves a level 3, she/he is considered proficient for this Power Standard, such that the student can construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

    If your child achieves a level 4, she/he is considered advanced for this Power Standard, because the student can evaluate evidence that supports the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
