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
Marine Debris
Young scholars will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.

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.

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...
