    4.  Select the sensor of the Micro:bit that control the movement of an arrow on the
                             screen.

                                    (i)  Tilt                                  (ii)  Temperature

                                    (iii)  Direction                           (iv)  Light

                         5.  Spot the block which is used to trigger an action when the Micro:bit is shaken.

                                    (i)  on shake                              (ii)  on start

                                    (iii)  on button A pressed                 (iv)  on tilt

                      B.  Write ‘T’ for true and ‘F’ for false.

                         1.   The compass sensor works based on the Earth's magnetic field.

                         2.   The Micro:bit uses a motion sensor to detect shaking, tilting and movement.

                         3.   The sensors cannot understand the world around them and detect
                             movement.

                         4.   Motion sensor can detect changes in speed and direction.

                         5.  The compass heading block can be found in loops category.

                      C.  Fill in the blanks using the given hints:
                         1.                  can detect  movement, direction,  temperature,                   Hints

                             light and more.                                                                Compass
                         2.  The Micro:bit can measure the angle of tilt along the                            Motion

                                            ,                and                  axes.                      Sensors
                         3.                  sensor quickly measures how much the Micro:bit                Directional
                             has moved.                                                                       X, Y, Z

                         4.  The                  sensor works based on the Earth's magnetic
                             field.

                         5.  In compass-based games Micro:bit reacts to                         changes.

                      COMPETENCY-BASED QUESTIONS

                      1.  Aman is building a security system using the Micro:bit. Which block would he use to
                         trigger an alarm when the device is moved or shaken?
                      2.  Priya is designing an interactive game using the Micro:bit. Which block would she use

                         to detect the tilt direction and display an arrow accordingly?
