Archimedes and the King's Crown
Learners will shout "Eureka!" in this quick but deep activity replicating the famous bathtub experiment of Archimedes. Given the scenario of a king with a suspected fake crown, young investigators develop formulas using density to...

Discovering Density
Students explore the physical properties of density. In this hands-on activity, students calculate density and distinguish between intensive and extensive properties.

What is Matter?
Students investigate what matter is and how it changes states. For this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter. Students perform a...

Heavy Ice: Day Five
Students explore physics by conducting a class experiment. In this density lesson plan, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five...
Curated OER
Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy instructional activity, students practice floating different items in two different liquids and identify why certain objects will float and others...
Curated OER
Recycling of Plastics
Students separate plastics according to their densities, develop a method for separation and identify variables in an experiment and a fair test, changing only one variable at a time for a fair comparison. After testing, they develop a...

The Sun as the Driving Force of the Water Cycle
Students study the water cycle and how the sun is an important factor. In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.
