Chapter 15 – Characteristics of Waves Click here for a copy to PRINT

Section I, C-Level - Basics Complete the following assignments as directed in (or out of ) class. We will correct the work as we complete it be sure to write down your scores. Some of the work will be collected and put into the grade book as an individual assignment, some you must keep to study from.

Late Unit sheets will lose 25 points each day late. If you do not add up your scores correctly or lie about scores you may receive 1/2 credit on the whole unit. In order to keep your parents informed of your work and what we are doing in class let them see this list of assignments. It must be signed before you turn it in. This can be done any time. This is REQUIRED or I will not accept your work.

Science Benchmark

Movement involves one form of energy being transformed into another form. Energy has the potential to exert a force over a distance. Waves transfer energy such as sound, heat, light, and earthquakes through different mediums. Sound and light waves allow organisms to "hear" and "see" the world around them. Energy is classified as either kinetic or potential energy.

Every object exerts a gravitational force on every other object. The distance between objects and mass of the objects determine the force of gravity between them. This force is difficult to measure unless one of the objects has a very large mass. Unbalanced forces cause change in the motion of objects, while balanced forces do not.

Standard IV: Students will understand the relationships among energy, force, and motion.

Objective 1: Investigate the transfer of energy through various materials.

a. Relate the energy of a wave to wavelength.

b. Compare the transfer of energy (i.e., sound, light, earthquake waves, heat) through various mediums.

c. Describe the spread of energy away from an energy-producing source.

d. Compare the transfer of heat by conduction, convection, and radiation and provide examples of each.

e. Demonstrate how white light can be separated into the visible color spectrum.

Objective 2: Examine the force exerted on objects by gravity.

a. Distinguish between mass and weight.

b. Cite examples of how Earth’s gravitational force on an object depends upon the mass of the object.

c. Describe how Earth’s gravitational force on an object depends upon the distance of the object from Earth.

d. Design and build structures to support a load.

e. Engineer (design and build) a machine that uses gravity to accomplish a task.

Science language students should use:

*Energy, *gravity, wave, *amplitude, Potential energy, kinetic energy, force, complex machine, * friction,
