The Online Lemonade Stand Project Whether you're a public school teacher or a homeschooler, the Online Lemonade Stand Project is a resource that brings practical business principles into your classroom.
Give teams fifty straws and one hundred paper clips to design the tallest freestanding tower they can build within the challenge rules. Students sketch a plan, build, test a 100 g load for thirty seconds, then refine the structure and reflect on stability and teamwork. Teacher guidance, a blueprint page and a science briefing support the lesson, with extension questions connecting classroom designs to larger engineering problems.
Problem-based learning (PBL) activity where students design and run an experiment (dropping a ball onto a target) to practice the scientific method, data analysis (mean, mode, standard deviation), and evidence-based argument writing.
A project-based environmental science curriculum reading students through the science of waste (lifecycle assessment, landfill/incineration/leakage), the neuroscience of habit formation, and the zero-waste hierarchy, with embedded comprehension checks; per the title, later sections (not reached in extraction) are meant to be habit-tracking journal pages.
