In this 8-13 day lesson bundle, students complete 3 lessons to engage in measuring, precision, and unit conversions.  This lesson bundle is intended for introductory science classes and can be scaled up or down as needed. 
 
Lesson 1: Flour & Flatbread: Measurements & Precision (2-3 days)
Explore the importance of precision and accuracy when measuring ingredients by gathering evidence in multiple activities that can be used to support a Claim in a Claim-Evidence-Reasoning response.
 
Lesson Flour & Chocolate Chip Cookies: Measurements & Precision (2-4 days)
Explore measurements, precision/accuracy, conversions and scaling through a classroom-friendly chocolate chip cookie recipe.
*This lesson builds and overlaps with some of the same content from Lesson 1, but expands this idea to unit conversions. It could be used as an assessment task.
 
Lesson 3: Scaling a Brownie Recipe: Volume, Units, & Heat Transfer (4-6 days)
Explore volume, unit conversions, and the relationship between energy transfer and mass by comparing pan sizes and scaling a brownie recipe.
 
Each Lesson Includes:
Teacher Lesson Plan with Essential Questions, Objectives, and NGSS standards, Lab Preparation (Materials, Ingredients, Amazon Lists when appropriate, and Tips & Tricks) and day-by-day lesson plans
