Picture this Overall learning objectives:  Developing a sense of scale and proportion with regard to measurement of frequency.  Understanding of concepts of sound and ultrasound with use of wave model.  Use of frequencies to compare waves.  Assessing the advantages of a particular technology. Page 2Introduction: Picture this

Picture this Overall learning outcomes:  To explain what ultrasound is and how it can be used to form images.  To explain how these images can be applied to medical diagnostic situations.  To use images and other evidence to form ideas and conclusions. Page 3Introduction: Picture this
