Yesterday we started working on our new STEM unit.  Yi Min's Great Wall.  We have read the story which is about a girl and a boy trying to build a wall to protect their garden at school.  They use the design process to create mortar mixtures that will hold their wall together.  We analyzed materials that could possible be used to create walls here is an example of our thinking.  We also discussed the design process they used in the book and filled in the engineering design process form to show the steps they went through.
