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,...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Engage young scientists in the upper-elementary and middle school grades with this collection of simple experiments. Whether you're teaching about heat transfer, density, or potential energy this resource has a lab for you.

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...

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...

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the...
