Double or More
Source Institutions
Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?
Are you a Supertaster?
Source Institutions
In this activity, learners examine their tongue and taste buds.
