Simulating Microgravity with Buoyancy
How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Pumpkin Science
Fourth graders examine pumpkins and use the scientific method to explore its contents. In this Pumpkin Science lesson, 4th graders measure pumpkins for circumference. Students dress as if they were in a lab and work in pairs to...

Density
Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.
Curated OER
Exploring Buoyancy
Learners use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...
Cornell University
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...

Ocean and Great Lakes Literacy: Principle 1
Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...
Curated OER
Liquids: Floating and Sinking
Third graders conduct an experiment. In this floating and sinking liquids instructional activity, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a...

Construct a Buoyant Scuba Diver
Groups of young oceanographers get to use action figures to experiment with the property of buoyancy! This memorable lesson plan provides detailed background information, a link to the laboratory worksheet, and thorough instruction...
Curated OER
I've Got That Sinking Feeling
Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!
Curated OER
Why Cheerios Don't Sink
Students investigate Archimedes' Principle and show how it relates to density. For this Archimedes' Principle lesson plan, students experiment with a beaker of water, a Styrofoam "boat" and a weight. They predict what will happen when...
Curated OER
Density and Mass
Students experiment to find which liquids are more dense. In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...
Reach Out!
Paper Clip Sailing
Students explore water, molecules, and surface tension. In this floatation lesson, students discover why some objects are able to float on water as they follow the procedures included in this activity.

Buoyancy Boats
What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design an object out...

MEASURING THE DENSITY OF WATER
Students perform an experiment to measure the density of tap water vs. salt water.
Curated OER
Grand Designs And Great Failures
Students extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or destroyers.
Curated OER
Ships 3: Grand Designs And Great Failures
Middle schoolers engage in this, the third in a three-part series on ships. The overall instructional activity series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to...

Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Rock My World
Students conduct a hands-on experiment designed to demonstrate how continents and oceans formed and why the manner of formation is relevant to a study of volcanoes.

Build Your Own Submarine
High schoolers construct their own submarine following a certain procedure. In this physics activity, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.
Curated OER
Density - An Introduction
Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...
