In this antonyms activity, students read the ten words in a column and add a missing letter to a word in a second column that will make an antonym.

In this Titanic's lifeboats worksheet, students read about the specific numbers of people on the lifeboats of the Titanic. Students answer 10 questions about the text.

Students study the structure of the lungs. In this lung structure lesson, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.

Investigate objects that float and sink in water.

Students determine whether a liquid will sink or float in water by comparing its density to the density of water.

Learn why some things will float or sink.

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the instructional activity, students will understand that density and weight are different and that density matters in...

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...

Why do hot air balloons float? This resource from the NOVA Web site offers a series of interactive activities that illustrates the physics of hot air balloons.

Students determine whether an object will sink or float by comparing its density to the density of water.

Predict and test everyday objects as to whether they sink or float.

This lesson plan is designed to have young children explore the concept of sinking vs. floating by using the skills of prediction, observation and classification.

Students sort objects according to whether they sink or float.

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.

Students find the densities of objects based on sinking or floating in this activity that demonstrates Archimedes Principle.

An experiment to determine if either a regular or a diet can of soda will float or sink when placed in water, and what causes this.

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.

This investigation introduces the concepts of volume, mass, and density and how they interact. Students will make predictions of whether an object will float or sink after finding mass and volume of an object.

Sixth graders predict if different types of coke will float or sink.

An experiment in density where colored water, both hot and cold, are poured into containers of water at room temperature. Students will observe that the warm water rises and the cold water sinks due to their different densities.

This is an inquiry-based activity in which students will need to work together as a class to solve the following problem: they must construct a "boat" entirely out of modeling clay that is capable of supporting 150 grams of cargo without...

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

Have you ever wondered how a ship made of steel can float? In this project you'll investigate how much weight boat hulls of various shapes and sizes can support without sinking.

A lesson where students learn how warm water is less dense than cold water, and what this means for global climate change as ice from the polar regions melts. Students will do experiments in buoyancy and water density when hot or cold,...
