This science unit for 2nd grade students introduces the concepts of push and pull forces and how they can make objects move in different ways depending on an object's size, shape, weight, and the surface it is moving on. It also explains how forces can change an object's shape and how gravity causes all objects to fall to the ground, with heavier objects hitting first due to their greater weight. Magnets are also noted for their ability to attract metal objects without touching them.

3. Push and pull forces can make an
object move in different ways:

4. An object can move easier or harder
depending on…
SIZE
SHAPE

5. An object can move easier or harder
depending on…
WEIGHT
SURFACE

6. Forces can change the shape of the
same object

7. Gravity
makes everything fall to the ground

8. Thanks to gravity, the heaviest object
will always hit the ground first

9. Magnets
attract objects made of metal without touching them
