In the past ten years we have written over fifty STEM units. These ranged from lower elementary units on magnetism and weather to upper elementary units on hydro power, garden design and swing-set physics.  Most units are designed to be completed in ten to twelve class periods.

Each unit is filled with science and math and these tools are woven through activities structured  on an engineering core:

• a problem or project scenario
• a design challenge
• an EDP outline
• interactive notebook prompts and inserts
