Rube Goldberg project was to feed the money pig. For our first step a ball rolled down an inclined plane and hit ten dominios. Then the dominios hit a marble for our second step. For our third step the marble rolled off a table and went through a funnel and triggered a mouse trap. In our fourth step the mouse trap went off and a popsicle stick fell off an inclined plane and made a golf ball to roll down it. For our fifth step the golf ball hit another ball on a table.

Purpose: In this lab‚ a mixture of naphthalene (C10H8)‚ common table salt (NaCl)‚ and sea sand (SiO2) will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically
