Density and Solubility of Liquids

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.    

Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

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...

In this forces in liquids worksheet, students read their notes and answer short answer questions about forces in liquids. Students complete 6 questions total.

After collecting carbon dioxide bubbles from a cup of club soda, learners attempt to make their own lemon soda while preventing the loss of carbonation. They do so by creating a syrup before mixing the substances into the club soda....

In this forces of nature worksheet, students read a 2 page article on the forces of nature and answer 4 detailed comprehension questions about the forces of nature on Earth.

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Will a grape float in oil? Will a metal nut sink in corn syrup? Watch as the ZOOM cast tests the buoyancy of a variety of liquids and objects. [4:22]

Students experiment with objects of different densities. In this density activity, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar...

Learners investigate factors affecting the rate of solubility. In this rate of solubility lesson plan, students experiment by crushing, heating and cooling solutes and solvents to see how the solubility is affected. For each situation,...
