Forces and Changes in Motion
Second Quarter
Learning Goal(s)
The student will understand the effects of various pushes and pulls on objects and be able to demonstrate
that the greater the force on the object, the greater the motion of the object.
Unit Overview
Students will learn that forces, pushes and pulls, can cause objects to move. That the speed at which an object moves is
related to the strength of the push or pull that initiated the movement of the object. Some forces act by touching, while
others can act without touching. Magnetic force can either repel (push) or attract (pull) certain objects.
Essential Question(s)
What are forces? How do forces make objects move? What are magnets? How strong is a magnet? How
can motion be described? How does friction affect movement? What kinds of forces act by touching?
How can a force act upon an object without touching it? Why is gravity important in our daily life?


observe that pushing or pulling on an object causes it to move
Be selective in choosing content from the textbook resource

observe that pushing or pulling on an object changes the directional movement of that object,
that meets the full intent of the focus benchmark(s).

Items may include a list of examples that students label with pushing or pulling.
SC.2.P.13.2:(DOK1 ) Demonstrate that magnets can be used to make some things move without touching
them.

use magnets and demonstrate that magnets can be used to move some things without touching
them

observe and explain that the amount of movement a magnet can cause on a magnetic object is
affected by the strength of the magnet and its distance from the object

explain that magnets can cause change in motion with or without touching some objects

recognize that the change in motion (pushing or pulling on the object) is dependent on the
direction the magnet is facing
FCAT 2.0 Content Limits:

Items will not include the uses of magnets.

Items may include a chart of items that students will label as magnetic or nonmagnetic based
on whether the magnet caused an object to move.
SC.2.P.13.3:(DOK 1) Recognize that objects are pulled toward the ground unless something holds them up.

demonstrate that an object will fall to the ground when dropped

explain that when something is falling it is actually being pulled by Earth with a force called
gravity

relate that the gravity of Earth is strong and pulls objects without touching them

observe falling objects (feathers, papers, balls, keys) and identify things that either slow down
the pull of Earth or prevent the objects from reaching the ground altogether (e.g., a heliumfilled balloon)
FCAT 2.0 Content Limits:

Items may include pictures that students can identify as pulled to Earth quickly, pulled to Earth

Physics Motion Activities for Second Grade:
Students will observe and discuss motion in
learning stations or in demonstration. They will
observe and discuss push and pull affects motion.

Forces and Movement: This interactive site will
have the students select items to complete a


Items may use the word weight instead of mass. Even though weight is not technically correct,
it is a better word choice for this age group.

Items will not discuss the gravitational pull of other planets or how Earth’s gravity affects other
planets.

Items will not discuss scientists who made discoveries in this field, such as Newton or Einstein.

SC.2.P.13.4: (DOK2) Demonstrate that the greater the force (push or pull) applied to an object, the greater
the change in motion of the object.

explain that force is a push or pull on an object that causes it to stop, change speed, or change
direction

demonstrate that the greater the force (push or pull) applied to an object, the greater the
change in motion of the object

observe and explain that the more massive the object being pulled or pushed, the more force it
takes to change its motion
FCAT 2.0 Content Limits:

Items will not discuss the concepts of kinetic or potential energy. Items may include an
animation of an object being given a soft or hard pull or push.

Students would then indicate whether the object would move to a closer or farther position.

journal two forces that move the truck and write at
least one sentence telling about what they learned
from the activity.

push (repel) and pull (attract).
What is Gravity? After reading the passage either as
an individual or groups, students will answer the 5
questions in complete sentences.
“Wonders - Literature Anthology”, after reading
“Move It!” pages 230 and 231, students will take a
tour of the playground, with their journals, while n

cause motion and explain how. Students will explain,
with examples, how force and speed are used in our
daily lives.

each of the simulations and the answers to the quiz
in the “My Journal”.
