10 STEM Challenges for Kids of All Ages

Pulley

Simple machines are part of the National Common Core Standards.  One of the most memorable activities I do in my classroom each year is a simple machine workshop in which we build all 6 simple machines.  The pulley activity is particularly cool for kids.  Some are more complicated than others but I like this one because it’s both inexpensive and easy to build.  Pull up the DIY info on Little Bins For Little Hands.
