Curated OER
Modeling Permutation Group
Students explore the concept of transformations. In this transformations lesson, students construct an equilateral triangle and a square with a circumscribed circle. Students reflect and rotate their constructions.
Curated OER
Rotations
Young scholars discuss the concepts of reflection, rotation, and translation. For this rotation activity, students investigate rotations through examples on an overhead projector. No additional worksheet or student assignment is included.
Curated OER
Comparison of Images Formed by Plane, Cylindrical, and Spherical Mirrors
Students observe how reflections differ in various types of mirrors. In this reflection lesson plan, students use cylindrical mirrors, plane mirrors, and concave mirrors to observe how each reflects the student's face.
Curated OER
To Absorb or Reflect...That is the Question
Students learn how different objects absorb and reflect sound. In this sound lesson plan, students actively listen to a lecture on sound absorption and sound reflection.
Curated OER
Notetaking Worksheet
In this notetaking worksheet, students practice the skill of notetaking by listening to the speaker, writing down key words and ideas. Then students reflect on their notes.
Curated OER
Transformations
In this transformations worksheet, 10th graders identify and complete 10 different problems that include various types of transformations. First, they label each figure with the correct term listed on the top. Students also identify and...
Curated OER
Transformation
In this transformation learning exercise, students identify and solve 10 different problems that include various images. First, they determine whether each object illustrated is a mirror image or reflection of the other image in the...

How Does Light Interact With Matter?
In this light worksheet, students will brainstorm problems associated with the interaction of light with matter. Then students will write in possible solutions to those problems in this graphic organizer.
Curated OER
Line Symmetry
In this line symmetry instructional activity, 10th graders solve 10 different problems related to various forms of line symmetry. They classify each line of symmetry illustrated as horizontal, vertical, both, or neither. Then students...
Curated OER
Enlightening Explorations, Part II
Sixth graders review their results from the previous experiments. After viewing a kaleidoscope, they make their own pattern on paper and describe the role of light. To end the lesson, they examine light being relfected and refracted and...
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...
Curated OER
Which Colors Absorb the Most Energy?
Students measure the temperatures over time of different colored envelopes in order to explore the different rates at which each color absorbs energy from a heat lamp. They record their data and graph their results.
Curated OER
Geometrical Optics: Reflection and Refraction of Light
Students define and discus the concepts of wave fronts and rays. In groups, they distinguish between specular and diffuse reflections and use Snell's Law to predict the path of light rays. They calculate the speed of light through...
Curated OER
Preparation -- The Right Way to Help and FOrm for Poetic Reflection
Students prepare for their service learning project by listening to a representative from the Lake Michigan Federation. They volunteer their time to clean up the coast line. They reflect on the event by writing a poem about their...
Curated OER
Reflection of Light With Two Plane Mirrors- Double Mirrors Placed at a Number of Angles
Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.
Curated OER
Magnificent Monet
Students research the water lily paintings of Claude Monet and the impressionistic art period. They create their own impressionistic art works and display them in the classroom.
Curated OER
Look What We Did Together!
Students reflect on and record what they do together as a class each week. They record it on a strip of butcher paper and draw a picture and write what they did.
Curated OER
Reflecting on Learning Experience
Students internalize learning experience by writing about it.
Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.
Curated OER
Reflection with a Friend
Students listen to story and respond with illustrations and comments.
