Division I (Grades 1-3)
Embedded Files
GRADE 1: Direction, pathway, and speed of moving objects.
GRADE 2: Sources, pathways, and behaviours of light and sound.
GRADE 3: Explain how forces affect movement of objects.
GRADE 1
Q. How can movement of objects be understood?
KNOWLEDGE
Movement that can be observed & described as:
direction
pathway
speed
UNDERSTANDING
Movement of objects can be observed & described.
SKILLS & PROCEDURES
Move objects in various of ways.
Observe & describe movement of objects.
Directions of movement can include:
• up • down
• forward. • backward • sideways
• toward • away from
Movement occurs in different directions.
Describe the direction of movement using appropriate vocabulary.
GRADE 2
Q. Where do light and sound come from, and how do they move?

KNOWLEDGE
Sources of light include
the Sun
electricity
fire
some plants & animals (bioluminescence)
Sources of sound include anything that produces sound vibrations, such as
musical instruments
speakers and headphones
vocal cords of humans and animals
objects hitting each other
UNDERSTANDING
Sources of light and sound can be identified.
SKILLS & PROCEDURES
Identify sources of light and sound.
Sound is caused by vibrations of objects and air.
Vibration is a rapid back-and-forth movement.
Characteristics of sound include:
volume (quiet or loud)
pitch (high or low)
duration (short or long)
Sound is produced by an interaction between objects or substances that causes vibration.
Relate vibration to the production of sound.
Listen to sounds and describe their characteristics.
GRADE 3
Q. How can forces relate to changes in movement?
KNOWLEDGE
A force is a push or pull upon an object resulting from an interaction with another object.
Contact forces occur between objects that touch each other.
Contact forces include forces that:
are exerted by a person or an object upon another object (applied)
oppose the movement of objects when they come into contact with other objects or surfaces (friction)
are exerted by pulling on a string or rope connected to an object (tension)
are exerted by a compressed or stretched elastic object or spring (elastic or spring)
Ways to apply a contact force to an object include:
stretching
pulling
squeezing
pushing
UNDERSTANDING
Contact forces can affect the movement of objects.
An object that is not moving will stay still until a force makes it move, and an object that is moving will keep moving until a force stops it.
SKILLS & PROCEDURES
Describe where forces may exist in everyday situations.
Perform simple experiments to demonstrate changes in motion.
Comparative vocabulary can be used to describe the strength of a force, such as:
stronger and weaker
larger and smaller
Vocabulary to describe the direction of a force on an object includes:
upward
downward
from the left
from the right
from both sides
from all directions
UNDERSTANDING
A force is characterized by its strength and direction.
SKILLS & PROCEDURES
Describe forces using vocabulary representing both strength and direction.
