Serc: Bowling Balls: Will They Sink or Will They Float?
Students will investigate what determines whether a material will sink or float. They will be given a bowling ball and have to make measurements and conclusions on whether their bowling ball will float, hover, or sink when placed in an...

Serc: Investigating Density in Solutions: How Can You Make an Egg Float?
For this activity, students will learn about density by determining how to make an egg float in water. By the end of the lesson, students will understand that density and weight are different and that density matters in floatation. They...

Serc: Mn Step: Sink or Float: All Liquids Do Not Have the Same Density
An experiment in density. After a review of floating and sinking of different materials, students test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar...

Serc: Mn Step: Sink or Float? Inquiry Investigation
For this activity, learners make predictions about whether different objects float or sink, then test them. They are asked to record their observations and results for each, and compare their results to others'.

Uen: 1st Grade Act. 01: Exploration Tubs
In this lesson, students will investigate different categories related to safety, organisms, sink or float, boats, seeds, and water droppers. Students will use exploration tubs to make observations.

Serc: Water Activity
Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.
Utah Education Network
Uen: 1st Grade Act. 24: Interactive Writing
In this lesson, students will listen to nonfiction books about items that sink and float. Students will participate in filling in words to fill in a teacher-created chart that is connected to the information. Students will then write a...

Alex: What's the Matter: A Sinker or Floater?
Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...

National Engineers Week Foundation: Flinker
Students investigate with common objects to see if they can make something that neither floats nor sinks, but rather "flinks" in the middle.

Science Is Fun: Bowling Balls Float or Sink?
In this experiment, you test whether two different bowling balls will float or sink, then determine the density of each of the balls to see if they are less than that of water.

Uen: Does Coke Float?
Sixth graders predict if different types of coke will float or sink.
National Association of Geoscience Teachers
Nagt: Density Mystery Canisters
Learners experiment with items that sink or float, and learn that water's density is equal to one, and objects/solutions with a density greater than one will sink, and those with a density less than one will float.
American Chemical Society
Inquiry in Action: Changing the Density of an Object: Changing Shape
Throughout the activities in this investigation, students may have wondered how a boat made out of steel, which is more dense than water, can float. This activity addresses that question. Students will see that changing the shape of an...
