This is a hands-on laboratory unit from the U.S. Department of Energy exploring the concepts of heat and movement. Teachers set up six laboratory stations that will introduce students to the basic concepts of thermodynamics, including atomic structure, atomic and molecular motion, states of matter, heat transfer, thermal expansion, specific heat, and heats of fusion and vaporization. It also includes a unit exam and teacher demonstrations.
Here is an interesting point as I research inquiry based learning and move to look in a database that is largely built from overseas. Many places called "inquiry" "enquiry" so in this set of lessons across the curriculum, I have to search using the term "enquiry" to turn up what have been tagged as "inquiry based" lesson plans.
There are many nuances like that as you start looking at best practices across the world to remember. Eventually, hopefully, language searches will translate between common languages (like English) to help us bridge best practices.
If you're looking into inquiry-based learning (or equiry-based depending upon where you're from) - this is a database of lesson plans from Kindergarten up in different categories.
