Oceanography: Density: Designing a Hydrometer Lab

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...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

Elementary and middle school physical science learners explore density in a hands-on lesson. They measure the mass and calculate the volume of different metal and wood blocks. From these two values, they compute the density for each....

What kind of design challenges are there in building structures to support rocket engines? The unit takes design teams through the process of building the lightest possible thrust support structure that can withstand the necessary forces...

Get kids' heads spinning by challenging them to design a top that will rotate for a minimum of 10 seconds without leaving a 30-cm circle. Groups of learners collaborate through a planning stage, testing stage, and evaluation stage. Some...

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and assessments....

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.
