Begin the lesson by discussing the concept of shadows. Ask students if they have ever noticed their own shadow on a sunny day. Explain that shadows form when an object blocks light.

Shadow Shapes
Learning Objectives
- Understand that shadows form when an object blocks light.
- Recognize that the shape of a shadow is similar to the shape of the object causing it.
- Experiment with creating different shadow shapes using a flashlight and various objects.
Introduction and Hook
Introduce the idea that the shape of a shadow is similar to the shape of the object causing it. Use simple examples like a tree or a person to illustrate this concept.
Direct Instruction
Explain that shadows are dark areas that form when something blocks light. Use a flashlight and an object to demonstrate how shadows are created.
Show the video 'Changing the Size of Shadows' to illustrate how the position of a light source affects the size of the shadow. This visual demonstration helps explain the relationship between light, objects, and shadows.
Guided Exploration
Encourage students to experiment with creating different shadow shapes using a flashlight and various objects. Discuss how the shape of the shadow changes with different objects.
Watch the video 'All About Light' to help students understand the essential role of light in visibility and its sources. This supports their understanding of how light interacts with objects to form shadows.
Hands-On Activity
Have students use their hands to create shadow shapes on the wall. Challenge them to make shadows in the shape of different animals and see if their classmates can guess what they are.
Use the assessment 'Light and Shadows' to explore how different hand gestures create various shadow shapes. This hands-on activity helps students understand the relationship between an object's shape and its shadow.
Independent Practice
Ask students to observe shadows in their environment at home. Encourage them to note the shape of the shadow and the object causing it.
Check for Understanding
Use the assessment 'Observing Shadows' to assess students' understanding of how light interacts with objects to create shadows. This activity engages students by having them identify the objects creating various shadows depicted in images.
Review and Reflection
Discuss with students what they learned about shadows and light. Ask them to share their observations from the independent practice activity.
Assessment and Extension
Use the quiz to test students' comprehension of the lesson on shadows and light.
Try the QuizFor further exploration, use the assessment 'Can You See in Darkness?' to investigate how objects can be seen in darkness only when there is light or if the object emits light. This encourages hands-on experimentation and critical thinking.
