Have you ever noticed that the salt you’re using says it’s “iodized”? Iodine is a micronutrient, which means we need it in small quantities to be healthy. Because iodine is relatively rare in many people’s normal diets, it’s added to table salt. Then when people salt their food, like tasty turkey, stuffing and mashed potatoes, they’re also getting some iodine. In this science activity, you’ll use some kitchen-friendly chemistry to investigate… Read more
