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...

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....

Tectonic relationships prove when there is too much friction, the fault lies near. This STEM science lesson is designed as a guided inquiry experiment. Scholars know the question but must choose their materials, formulate their...

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,...

Using a stream table, erosion enthusiasts examine how the density of sediment and how the slope of land contribute to the amount moved by waves. You will not be able to use this entire resource as is; there are teachers' names and...

For this student-designed experiment worksheet, middle schoolers decide on an experimental problem to solve. Students use the scientific method to perform an experiment and record the data. Middle schoolers calculate the density of...

Starting with a guide to finding the density of water using a graduating cylinder, this lab sheet also provides the steps for an unknown liquid sample.  The steps for the calculations are given and pupils are expected to design their own...

This is a strong visual display of density. It requires a mountain of materials and is quite messy, so you most likely will not want to have lab groups perform this activity. You could demonstrate it for your class when exploring the...

Students investigate the properties of liquids, solids and gases. They apply their research in the design and construction of a hot air balloon. The balloons are displayed along with a multimedia presentation on the topic of density.

This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...
