First graders love experimenting and pretending to be scientists. They also enjoy playing in the kitchen and mixing ingredients to create something new. It's especially exciting for them when they can make something change in some unexpected or dramatic way. In this activity, your child will learn scientific terms such as "acid" and "base", "chemical reaction" and "indicator" as she watches liquids change colors. She'll love being a “colour Scientist” and—who knows—this activity might even spark an interest in chemistry!
