Grade 4 Model Science Unit 8: Waves and Information (draft 11.18.15) Instructional Days: 20 Unit Summary How can we use waves to gather and transmit information? In this unit of study, students use a model of waves to describe patterns of waves in terms of amplitude and wavelength and to show that waves can cause objects to move. The crosscutting concepts of patterns; interdependence of science, engineering, and technology; and influence of engineering, technology, and science on society and the natural world are called out as organizing concepts for these disciplinary core ideas. Students demonstrate grade-appropriate proficiency in developing and using models , planning and carrying out investigations , and constructing explanations , and designing solutions . Students are also expected to use these practices to demonstrate their understanding of the core ideas. Student Learning Objectives Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move. [Clarification Statement: Examples of models could include diagrams, analogies, and physical models using wire to illustrate wavelength and amplitude of waves.] [Assessment Boundary: Assessment does not include interference effects, electromagnetic waves, non-periodic waves, or quantitative models of amplitude and wavelength.] ( 4-PS4-1 ) Generate and compare multiple solutions that use patterns to transfer information. [Clarification Statement: Examples of solutions could include drums sending coded information through sound waves, using a grid of 1’s and 0’s representing black and white to send information about a picture, and using Morse code to send text.] ( 4-PS4-3 ) Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem. ( 3-5-EST-1-2 ) Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

Grade 4 Model Science Unit 8: Waves and Information (draft 11.18.15) Instructional Days: 20 Unit Sequence Part A: If a beach ball lands in the surf, beyond the breakers, what will happen to it? Concepts Formative Assessments Science findings are based on recognizing patterns. Similarities and differences in patterns can be used to sort and classify natural phenomena.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
