This bilingual SciGirls en Español activity is a set of two components that builds on the model of science inquiry presented in the short, Spanish language DragonflyTV-SciGirls en Español video. Educators are encouraged to use the companion video as a catalyst or motivator to get students enthused about doing science investigations. In Maquillaje (Makeup), Jazi and Danielle develop and test their own lip gloss, varying the formula and trying it out on prospective customers. The activity set begins with an Icebreaker, a simple activity which introduces one skill that is part of the full inquiry process. The icebreaker activities are intentionally short, lasting perhaps 30 minutes to one hour. In this quick activity, learners will investigate how the tiny molecules of scent from makeup, lotions, and perfumes make their way to the nose by placing drops of vanilla extract in a balloon then sniffing for any vanilla scent that escapes through the wall of the balloon. The second component of the set is a main Investigation, a more rigorous activity that includes all the elements of a full science inquiry. This activity is often a replication of the video investigation seen on SciGirls en Español. Allow an hour or two to complete a main Investigation, perhaps even letting it spill over across several days. This activity is an investigation into testing and optimizing a formula for lip gloss. Learners will create their own homemade lip gloss using a basic formula and food grade ingredients, further customize their formula, then gather friends and family to collect data to see which lip gloss they prefer and why.
