Adding dyes to salting out experiments can create a variety of interesting color effects as the dyes differentially dissolve in the aqueous and organic layers. Can this differential solubility of dyes be explained using intermolecular forces as a guide?
Nina Hike shares a storyline and lesson that seamlessly integrates NGSS with a culturally relevant storyline, making learning chemistry both engaging and impactful.
Nora Walsh reflects on her experience using phenomena in her chemistry courses and assessments for the first time.
The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
The concepts of Measurement and Significant Figures can induce discomfort for both teacher and students. Michael Jansen shares his approach to teaching this important topic.
Find out how laboratory activities can be used as the starting point for scientific model development rather than as the endpoint, or verification, of concepts presented in lecture. This post deals with density.
Continuation of the practical application of chemistry to seemingly something unrelated- global maritime trade. In this classroom activity students predict the buoyancy (and hence stability) of a merchant cargo ship based on interpretation of seawater surface salinity values. Like in the first three posts, the question types are conceptual.
This is the second blog post describing a classroom activity relating seawater chemistry to oceanic shipping. Included are questions that challenge students to apply conclusions drawn from observations to making predictions.
Maritime shipping is the backbone of global commerce and trade. How is the chemistry of seawater involved in the complex, intertwined network of international trade? Let's find out.
The Wisconsin initiative for Science Literacy has published Science Climate Concepts Fit Your Classroom - A Workbook for Teachers. This is a free online Workbook, readily available for secondary teachers and college faculty. This workbook includes many hands on activities that incorporate traditional science classroom concepts within the context of climate science.
