Newton’s 3 Laws Technology Utilized: Activboard Khan Academy (www.khanacademy.org)- Newton’s 1st, 2nd, and 3rd Law Videos USA Test Prep (www.usatestprep.com) – Newton’s Laws Practice- Create your own or use previously created activities www.usatestprep.com Gizmo’s (www.explorelearning.com) - Force and Fans / Measuring Motion

Newton’s 3 Laws S8P3: Students will investigate relationship between force, mass, and the motion of objects. a) Determine the relationship between velocity and acceleration. b) Demonstrate the effect of balanced and unbalanced forces on an object in terms of gravity, inertia, and friction. S8P5 Students will recognize characteristics of gravity, electricity, and magnetism as major kinds of forces acting in nature. a)Recognize that every object exerts gravitational force on every other object and that the force exerted depends on how much mass the objects have and how far apart they are.

Newton’s 3 Laws Essential Question: How do Newton’s Three Laws of Motion affect our daily lives? Learning Target(s): Students will use Newton’s Laws to describe motion. What should students KNOW? What should students DO? Motion is change in an objects position over time relative to a frame of reference. Speed is a measure of the distance traveled per unit of time. Velocity is speed in a particular direction. Acceleration is the change in velocity per unit of time. Acceleration depends on force and mass. A force is a push or a pull. Explain the relationship between velocity and acceleration. Use the formula v=d/t to calculate speed, distance, and time. Use the formula a = (vf-vi)/t to calculate acceleration. Use graphs to describe the motion of objects. Use Newton’s laws to describe motion. Use the formula p = m x v to calculate momentum.

Newton’s 3 Laws ActiviBoard Do Now: Activity to complete upon entering the classroom Possible Sentences – students will write three possible sentences using content vocabulary. Each sentence must contain two words from the list below. Motion Speed Velocity Acceleration Force Newton Net force Inertia Friction Frame of Reference Mass Gravity Weight Distance

Waves S8P4: Students will explore the wave nature of sound and electromagnetic radiation. a. Identify the characteristics of electromagnetic and mechanical waves. b. Describe how the behavior of light waves is manipulated causing reflection, refraction, diffraction, and absorption. c. Explain how the human eye sees objects and colors in terms of wavelengths. d. Describe how the behavior of waves is affected by medium (such as air, water, solids). e. Relate the properties of sound to everyday experiences. f. Diagram the parts of the wave and explain how the parts are affected by changes in amplitude and pitch.

WAVES Essential Question: 1) How are light waves affected by reflection, refraction, absorption and diffraction 2) What causes us to see the color red? Learning Target(s): Students will use key terms to describe light wave properties and behaviors. What should students KNOW? What should students DO? Waves carry energy that can be transferred or transformed in interactions with matter or other waves. The pitch of sound is a measure of its frequency. The speed at which sound travels is dependent upon the material in which it travels. As a wave encounters an obstacle or an opening it may be reflected, refracted, and/or diffracted. The energy of a wave can be determined from the wave’s physical characteristics. Discuss the features of electromagnetic and mechanical waves. Draw a picture of the parts of a wave and explain how those parts change when the size of the wave changes and when the pitch of the wave changes. Describe how changes in light waves cause reflection, refraction, diffraction and absorption Explain how light waves with different properties are detected by the human eye as different colors. Explain how sound affects your everyday life.
