ViewUse Compare in the View area to examine the data from your car and from thePilot program. Look at the maximum value of each line. Did your car find thebrightest spot?JournalUsing the Describe template to write a conclusion to your experiment. Developanswers to these questions:1) Did your system optimize the available light?2) How could you improve your car and program if you had more time?PresentCreate a presentation of your experiment containing the following pages: Journalpage describing the car and algorithm, Program page, Data page(s), Journalpage of conclusions.©2002 The LEGO Group.

Teacher’s Notes for Here Comes the SunLEARNING OBJECTIVES________________________________________________________________Students will understand:ü How to write a computer program that includes sensors.ü What an algorithm is and why it is useful.ü That, through experimentation, a value (such as light intensity) can beoptimized.ü That sensor readings provide feedback to control the behavior of a device.DISCUSSION________________________________________________________________This activity can be used in a number of different ways. For example, thestudents could be given plans for building the car and could concentrate onprogramming it. Or, students could be given one or more algorithms to programand test, rather than inventing their own.Building IdeasThe car can be built using one or two motors. The student handout assumes thatthe students will build their own two-motor cars. Alternatively, they can be givenbuilding plans for single-motor cars. This design will allow the car to go forwardor turn using just one motor.Sample building idea for a one-motor car:©2002 The LEGO Group.
