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.
Who is not interested in food, right? Why not use what happens in the kitchen everyday to teach some chemistry? This blog post shares some conceptually based questions based on the information found on the backside of a popular dry mix brownie product.
Assembling a large graduated cylinder with colored sugar solutions of various densities is described. By filling the cylinder in the reverse order from bottom up, very little mixing occurs resulting in an attractive classroom demonstration to illustrate density. Students also have to opportunity to practice density and dilution calculations.

Per label, 39 grams of table sugar (sucrose) are in a 12fl.oz. can of a Red Bull beverage. Visually, how much is 39 grams of anything? Check it out in this post.
Observing the floating and sinking behavior of diet and sugared sodas is a classic chemistry demonstration. Learn how to perform this experiment as a quantitative lab that can be accomplished as an at-home activity!
Have you seen the rainbow candy experiment? It's a very simple experiment that involves pouring water into a plate that has M&M's candies or Skittles arranged in a pattern. Very curious shapes of sharply divided regions form spontaneously. How does this happen?!
