Sunlight and Temperature
Students will investigate how sunlight can warm objects and surfaces through hands-on experiments and data collection.
Key Questions
- Compare the temperature of an object in the sun to an object in the shade.
- Design an experiment to show how sunlight can warm water.
- Explain why a dark-colored object gets hotter in the sun than a light-colored object.
Ontario Curriculum Expectations
About This Topic
Investigating Light explores how light behaves when it hits different objects. Students learn that light travels in straight lines and can be blocked, reflected, or passed through. The Ontario curriculum focuses on classifying materials as transparent, translucent, or opaque. This topic is essential for understanding how we see and how technology, like mirrors and windows, works in our daily lives.
Students also explore the creation of shadows and how their size and shape can be manipulated. This topic is highly experimental and thrives in a 'darkened' classroom environment where light sources become the focus. Students grasp this concept faster through hands-on modeling where they can move light sources to see immediate changes in shadows.
Active Learning Ideas
Stations Rotation: Light Pass-Through
Students visit stations with flashlights and various objects (wax paper, cardboard, clear plastic, a mirror). They sort the objects into three bins based on whether the light goes all the way through, some through, or none through.
Simulation Game: Shadow Puppets
In pairs, students use a light source and their hands to create shadows on a screen. They experiment with moving their hands closer to and further from the light to see how the shadow's size changes.
Inquiry Circle: Mirror Maze
Groups try to 'bounce' a beam of light from a flashlight off a series of small mirrors to hit a target on the wall. This helps them visualize that light travels in straight lines and can be reflected.
Watch Out for These Misconceptions
Common MisconceptionShadows are 'things' that come out of objects.
What to Teach Instead
Students often think a shadow is a physical part of the object. Active modeling with flashlights helps them see that a shadow is actually just the *absence* of light where an object blocked its path.
Common MisconceptionLight only travels as far as we can see it on the floor.
What to Teach Instead
Children often think light 'stops.' Using a dusty chalkboard eraser or a little fog in a jar can help students see the beam of light traveling through the air, proving it continues until it hits something.

Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
