This lesson I did with my kindergarten class. Students will measure (we created our own measuring cups using clear cups and marked them with a sharpie), and also the learn the beginning science terms of observe, dissolve, suspension and solution. They will investigates what types of mixes are created when they mix salt with water, and pepper with water. Will it be a solution or suspension? There is a youtube video that helps introduce the topic, and a checklist for students to complete the task on their own, or with a partner. Easy STEM lesson for your students!
