2. Science Olympiad Mission The mission of the Science Olympiad is to promote and improve student interest in science and improve the quality of k-12 science education throughout the nation. The purpose of the competition is to emphasize problem solving, develop teamwork, make science exciting, promote a commitment to excellence, and attract more students to careers related to science.

3. Crave the Wave 2 nd year for this event Division B ( grades 6- 9)

4. Description “Students will demonstrate knowledge and process skills needed to solve problems and answer questions regarding all types and areas of waves and wave motion.”

5. National Science Education Standards Crave the Wave is not just an interesting, fun event but also a challenging one based on several National Science Education Standards.

6. National Science Education High School Standard B Physical Science - Physical science focuses on science facts, concepts, principles, theories, and models that are important for all students to know, understand, and use. H.B.5.b – H.B.6.a,b

7. National Science Education Standards H.B.5 - Conservation of energy and increase in disorder b. All energy can be considered to be either kinetic energy, which is the energy of motion; potential energy, which depends on relative position; or energy contained by a field, such as electromagnetic waves.

8. National Science Education Standards H.B.6 - Interactions of energy and matter a. Waves, including sound and seismic waves, waves on water, and light waves, have energy and can transfer energy when they interact with matter.

9. National Science Education Standards H.B.6 - Interactions of energy and matter b. Electromagnetic waves result when a charged object is accelerated or decelerated. Electromagnetic waves include radio waves (the longest wavelength), microwaves, infrared radiation (radiant heat), visible light, ultraviolet radiation, x-rays, and gamma rays. The energy of electromagnetic waves is carried in packets whose magnitude is inversely proportional to the wavelength.
