Tips
Extend the experience by turning the market into a multi‑week project: have students keep a detailed ledger to graph weekly profit trends, then analyze which pricing or packaging changes boosted sales. Pair the scrub‑making with a simple chemistry experiment—test how different oils affect the rate of sugar dissolution and record observations. Invite a local business owner to discuss budgeting, marketing, and customer service, followed by a role‑play where students draft a short commercial script. Finally, incorporate a community‑service angle by donating a portion of proceeds to a local charity, prompting a reflection journal about social responsibility.
