A Learning Activity is a strategy a teacher chooses to actively
engage students in learning a concept or skill using a digital tool/resource.

Phase:
After/Explain/Elaborate
Activity:
The teacher will ask the students what translucent, opaque, and transparent mean. The teacher will display a Lego and ask whether the object is translucent, transparent, or opaque.
Students will respond that it is opaque. Ask them what happens if we shine a light on the object. Students should respond by saying the Lego will not allow light to pass through and that it can create a shadow.
Give groups of students (two to four students each) a bag of Legos. Tell students they are to build a tower using the Legos so that they can then use the opaque object to cast a shadow on their paper.
Allow students the ability to manipulate a flashlight to cast a shadow off of the tower they created onto a piece of paper. Another student will trace the shadow using the pencil. Have students repeat this step until all students have a traced shadow.
Ask students to share why their shadows might look different. Some answers will be different shapes and the difference in how far or close the light was to the object.
Next, have students turn this traced shadow into a piece of art using their imagination. Students may use any media to complete this project.
Assessment Strategies:
Teachers will take up artwork and assess student work for completion.
The teacher will observe student responses during the initial discussion to assess students' knowledge of opaque, translucent, and transparent materials. The teacher will observe the students' investigation of building materials.
Advanced Preparation:
Students need to be placed in groups of two to four.
Each group will need a bag of Legos, a flashlight, and a pencil.
Each student will need a piece of blank paper to trace a shadow. Legal size paper works best.
Students will need to have an understanding of the terms translucent, transparent, and opaque.
Variation Tips (optional):
Any opaque building object will work for this activity.
Notes or Recommendations (optional):
You might need to help students keep flashlights still when they are tracing the shadow.
