Waves - Case Studies - Directions
Using the Case Studies: Waves Concept Builder is quite simple. You will be presented with a wave pattern displaying a particular wavelength and amplitude. There is a grid in the background to assist in obtaining a quantitative measure of both wavelength and amplitude. You will then be asked to identify the wave pattern that results for a particular change. For instance, you might be asked to determine the wave pattern for the case of two times the wavelength and one-half the amplitude. There will be three choices, with each choice being a diagram of a wave pattern. You can select an answer by tapping on one of the diagrams. The diagram will be highlighted by a grey box and the Check Answer button will appear. If you are not satisfied with your answer, then you can tap on another choice. Tapping on a selected choice removes the selected answer and hides the Check Answer button. When you are satisfied with your answer, tap on the Check Answer button. Your answer will be evaluated and feedback will be given. The Progress Report will be updated and you will be given a new question.
Your goal is to earn "Stars" and to complete one or more activities. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular activitiy, you will earn the Trophy for that activitiy.
