April 8th -18th

Students explored simple machines and the uses of simple machines in complex machines. They had to complete a Rube Goldberg cartoon which was due Monday, April. 15th.  Students then investigated Work, Mechanical Advantage, Speed Ratio, and Efficiency. Thursday April 18th they completed a topic 1-3 quiz.  Students will begin looking at Force and Pressure when they are back from the long weekend.  If students completed all in class work than there is no homework over the long weekend.
