Spectrum - Directions
Using the Spectrum Concept Builder is quite simple. There are two question types in each of the two activities. The first type involves ranking three regions of the EM spectrum or three colors of the visible spectrum in order of their wavelength, their frequency, or their energy. The three regions (or colors) are listed and a ranking box is displayed to the right of the name. Tapping on the box toggles through possible ranks - smallest, middlest, and greatest. Continue tapping until you are satisfied with the rank. Once all three ranks are used, a Check Answer button appears. Once you are satisfied with your answer, tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated.
The second question type involves identifying all those regions of the EM spectrum or colors of the visible spectrum that have a greater wavelength, frequency or energy than a specified region or color. All the remaining regions (or colors) are listed and you must identify those with the greater wavelength (or frequency or energy). This can be done by simpling tapping on the name of the region (or color). Tapping once hilights the option; its text turns red and the radio button to the left of the text is turned on; Tapping a second time deselects the option. You must select all that apply. As long as one of the options is selected, a Check ANswer button is displayed. Once you are satisfied with your selection(s), tap on the Check Answer button. Your answer(s) will be evaluated and your Progress Report will be updated.
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 activity, you will earn the trophy for that activity.
