Curated OER
MEASURING THE DENSITY OF WATER
Learners perform an experiment to measure the density of tap water vs. salt water.

Displacement and Density
High schoolers explore displacement. In this displacement and density lesson plan, pupils find the volume of irregular shaped objects. Afterward, they determine the volume of containers. They compute the amount of water displacement.

Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...
Curated OER
Volume Lab
How can we find volume if it a shape isn't easy to measure? Investigate methods for determining this as the volume of regular and irregular objects is explored in several stations. Learners discover that when the standard formula for...
Curated OER
Displacement of fluids
Learners understand the meaning of volume. In this displacement of liquid lesson, students experiment with various weights and a balance scale to find the liquid displaced.
Curated OER
Water Displacement to Determine Volume
Sixth graders explore the water displacement method to determine the volume of solid objects such as rocks, nails, and marbles.
Curated OER
Rising Waters
Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Worksheet 26: Vector Force
In this vector force worksheet, students determine the total velocity of objects, the displacement direction, and vector movement. This two-page worksheet provides a total of six multi-step problems.
Curated OER
Density as a Unique Physical Property
Learners find the density of objects by finding their mass and their volume. In this density lesson plan, students determine the mass of objects, the find the volume by using formulas or by water displacement and they calculate the...

Barge Building: What Floats Your Boat?
Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.
Curated OER
Move that Tower
Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.
Curated OER
Concrete Canoes
Learners explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.
