Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Students extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or destroyers.

Students make and test predictions about sinking and floating, and classify objects according to whether they sink or float.

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

How does a scuba diver control whether they sink or float? Scholars observe the relationship between absolute pressure and depth below the surface in an undersea simulation. They control the diver size and depth to center of mass to...

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...

Students investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Students measure and dissect...
