Student Exploration: Density Laboratory
In this density laboratory worksheet, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

How Does the USS Alabama Float?
Students investigate buoyancy. In this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.
Curated OER
Cartesian Diver Lab
In this Cartesian diver lab, students explain using text and diagrams how the Cartesian diver works. Students evaluate ways in making their lab design better. Students make predictions of how changing the variable would change the...
Curated OER
Biocomplexity Lab Activity: Density and Buoyancy of
Students investigate how the density of water changes the buoyancy of
water. Students create a hypothesis about what will happen when placing the
egg into the water.Students can research online different bodies of water (The Red Sea, The...
Curated OER
Floating Vegetables
Students design a craft that safely floats vegetables across a classroom. The teacher provides some materials, but the child may as well. As the experiment is created, they have to fill out worksheets to keep the actiivity organized....
Curated OER
Density and Buoyancy Experimental Design
Students must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."
Curated OER
Hot Air Balloon
Students view a video and discuss the mechanics of a hot air balloon. They, in groups, construct a functioning hot air balloon.
Curated OER
Earth: The Water Planet
Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.

Paper Clip Sailing
Students explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.
Curated OER
Diving Raisins
Young scholars hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.
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.
Curated OER
Technology of the Deep: Experiments with Buoyant Forces
Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.
Curated OER
Float Your Boat
Students design an experiment to find density using Archimedes' Principle. In this physics lesson, students calculate density using mass and volume. They share their findings in class.
Curated OER
Condiment Diver: The World's Simplest Cartesian Diver
Students explain what density is in their own words. For this physics lesson, students perform the condiment experiment and explain why some float and some sink. They share their findings in class.

What Boat Designs Float the Best?
Fifth graders investigate buoyancy by conducting a science experiment. In this water properties lesson, 5th graders predict which of their different paper boat designs will float for the longest period. Students conduct the experiment...
Curated OER
Radical Raisins!
Students explore the concept of buoyancy through experimentation. Given materials of various weights and composition, they drop them in club soda and determine which substances sink or float. Students discuss their results in terms of...
Curated OER
Clay Boats
Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...
Curated OER
What Floats Your Boat?
Learners discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.
Curated OER
Buoyancy
Students look at clippings of boats. They are able to define the following terms displacement, and density. Students construct a clay boat. After they complete their clay boat students answer questions about their clay boats.
Curated OER
The Buoyancy Factor
Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...
Curated OER
Secrets Beneath the Waters
Students work in small groups and design a ship out of balsa wood. They hypothesize what happens when the ship is placed in water then make predictions as to which ship stays afloat the longest with the greatest amount of weight added.
Curated OER
How Wet Can You Get?
Students visit a swimming pool and brainstorm different water sports and what benefits swimming has over other types of exercise. They then discuss buoyancy and water pressure and when how objects sink or float before playing a game of...
Curated OER
Galapagos Rift Expedition Come On Down!
Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. In this oceanography lesson, students calculate the density of objects by determining the mass and volume.
Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
