[b]Background[/b][br]Shirley likes designing skateboard equipment.  After she completes her designs, she shares her construction plans with other skateboarders on her website.[br]She is experimenting with different ramp angles as she tries to find just the right combination for her new design.[br][br][b]Collect Data[/b][br]Shirley needs the following data to help with her design. Make a Data Table on a piece of paper:[br][br]Data Table [br][u]Number of Blocks              Ramp Angle [/u][br]1 block [br]2 blocks [br]3 blocks [br]4 blocks [br]5 blocks [br]6 blocks [br][br]Use the MOVE tool [icon]/images/ggb/toolbar/mode_move.png[/icon]to lift the ramp (by the yellow point at the end) and to move [br]blocks under the ramp to raise it for the measurements.[br][br]When you are ready to measure the angle between the ground and the ramp, use the MOVE tool [icon]/images/ggb/toolbar/mode_move.png[/icon]to drag the protractor into place.
