Got Science!

Each of the Got Science! content standards is explored on two levels. Each video serves as a point of departure. The student videos introduce the Physical Science academic content standard and underlying concepts in an engaging manner designed specifically for 9th grade students. The instructor development videos examine the academic content standards in greater detail, and provide instructions for in-class demonstrations, and recommended topics for further discussion with the students.

Wave Behavior: Reflection and Superimposition

Show how the properties of a wave depend on the properties of the medium through which it travels. Recognize that electromagnetic waves can be propagated without a medium. Describe how waves can superimpose on one another when propagated in the same medium. Analyze conditions in which waves can bend around corners, reflect off surfaces, are absorbed by materials they enter, and change direction and speed when entering a different material.

Student Video - 4:22 min.
Waves are a form of energy. Using a ripple tank this video demonstrates the characteristics of water wave reflection, wave frequency, wave length and wave superimposition.

Teacher Video - 4:03 min.
Energy creates waves. The Got Science instructor demonstrates the classroom use of a ripple tank and in that process describes wave reflection, wave frequency, and angle of reflection.
