Update

We are now in our 3rd Science Unit Pulleys and Gears.  We have identified the 3 main pulleys systems ( e. g.  fixed, movable and compound) and found some systems that are used in our daily lives ( e.g. clotheslines, flagpoles, cranes).  We even built the systems in class using small pulleys, string and a weight which helped us to understand the purposes of pulley systems.  We have also identified types of gears   ( (e.g. spur gears, bevel and worm gear) and found some systems that are used in our daily lives ( bicycles, can openers and drills).
