They begin by investigating the properties of inclined planes and how implementing them can reduce the force necessary to lift objects off the ground.  </summary><engrConnection>Engineers are constantly looking for and designing new tools to make life easier.  Students are introduced to this idea by exploring tools that they know and see everyday, in particular the inclined plane.  They then use these ideas to identify tasks in their own lives they would like to make easier and design tools to help them accomplish this.  </engrConnection><learningObjectives><learningObjective>Identify inclined planes as a type of simple machine.  </learningObjective><learningObjective>Identify at least one way in which simple machines make a specific task easier to accomplish.  </learningObjective><learningObjective>Explain that the purpose of simple machines and tools is to make a specific type of work or task easier to do.  </learningObjective></learningObjectives><timeRequired unit="minutes">50</timeRequired><publisher>TeachEngineering.org</publisher><contributors><contributor>Mike McGroddy</contributor></contributors><requirements><requires>http://www.teachengineering.org/collection/duk_/lessons/duk_heaveho_music_less/intro.pdf</requires><requires>http://www.teachengineering.org/collection/duk_/lessons/duk_heaveho_music_less/intro.doc</requires><requires>http://www.teachengineering.org/collection/duk_/lessons/duk_heaveho_music_less/experiment.pdf</requires><requires>http://www.teachengineering.org/collection/duk_/lessons/duk_heaveho_music_less/experiment.doc</requires><requires>http://www.teachengineering.org/collection/duk_/lessons/duk_heaveho_music_less/design.pdf</requires><requires>http://www.teachengineering.org/collection/duk_/lessons/duk_heaveho_music_less/design.doc</requires></requirements><eduStandards><eduStandard><id>S100E7DC</id><locale>American_Assoc_Advancement_of_Science_Proj_2061</locale><type>Science</type><description>8B (K-2) #3 Tools are used to help make things, and some things cannot be made at all without tools.
