Comparing the Density of an Object to the Density of Water
Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Finding Volume: The Water Displacement Method
We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...

Tossing Cylinders
Everyone loves a lesson that involves throwing things around! To understand probability, your experimenters will predict how different cylinder-shaped objects will land when tossed. When the data is collected, they will calculate the...

Operations and Algebraic Thinking
How to use the relationship between multiplication and division to solve math word problems is the focus of the instructional activity presented here. In it, fourth graders work in groups to solve problems posed by the teacher. Then,...

Planetary Distances on the Playground
There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

Phonics: Letter- Sound Correspondence, Brown Bag It
Sorting objects according to their initial sound get scholars thinking about letter-sound correspondence. With 26 brown bags labeled with a letter of the alphabet, learners browse magazines and cut out images that begin with the...

Why Does the Wind Blow?
Without wind, the weather man wouldn't have much to talk about! Blow away your junior meteorologists with a creative demonstration of how wind works. The activity uses an empty soda bottle and compressible Styrofoam peanuts to illustrate...

Two Wheels and a Belt
Geometry gets an engineering treatment in an exercise involving a belt wrapped around two wheels of different dimensions. Along with the wheels, this belt problem connects concepts of right triangles, tangent lines, arc length, and...

Projectiles: Target Practice
Angry Birds prepared them, but now pupils must prove their skills with projectiles! Scholars test different variables to determine which ones impact the distance the projectile flies. The experiment provides connections to kinetic and...

Viscosity: The Fluid Lab
There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

Defining Density
Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

What is Density?
Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...
Cornell University
Constructing and Visualizing Topographic Profiles
Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

The Newton Challenge
Make Newton proud. Scholars apply their understanding of forces and energy to an engineering design challenge. They learn about simple machines, create a presentation on Newton's laws, and develop a balloon-powered car.
