The transition of our inventory to a new warehouse is taking longer than we anticipated. As a result, we are experiencing fulfillment delays and order(s) are taking longer to ship out. We are working hard to get the stock moved to our new facility as quickly as possible so that we are better equipped to meet your needs. We apologize for any inconvenience this may cause you.

What’s the Next Step?

by: John Zenchak and Mary Jean Lynch

The authors developed a demonstration with two similar setups that provide students with both the prior experience to form an expectation and the discrepancy to grab their attention. They follow the demonstration with a structured exploration format that gives students a method for experimenting to find the one built-in difference (i.e., the variable) that caused the different results between the two setups. Because the demonstration-experiment approach can be applied to various science content areas, inquiry is not the focus of just a single unit, but is used to teach content throughout the school year. This article describes one such activity that deals with the concepts of density and convection currents and is called “Chill Out.”
