Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

Second graders explore floating and sinking and make predictions about whether certain objects are likely to sink or float. They read the story Who Sank the Boat? by Pamela Allen. Pupils loacate rhyming words and discuss the events of...

Students explore sinking and floating.  In this buoyancy instructional activity, students conduct an investigation dealing with regular and diet soda. Students drop various soda cans into water and then discuss why some float...

First graders discuss and predict if a given object sinks or floats. They record their predictions on a data sheet. Pupils test the objects and organize them into floating/sinking groups. Students observe the floating and sinking of a...

Students perform experiments to see if items will sink or float. In this sink or float lesson, students work in groups to make predictions, and record the results. After the experiments are complete students make a book of the results.

How can you place a rectangular tile around a pipe? Scholars first use a model of a kitchen sink cabinet to take measurements. Using a compass and their knowledge of circles, they then cut out a circle from a piece of poster board (which...

Students observe and classify objects that float or sink.

An engating lesson plan relates mass and volume to better understand density. Young scientists explore and experiment with floating and sinking as well as density cubes. Then, they solve how to make a sinking item float.

What sunk the Sultana? Scholars become investigators to uncover the facts behind the 1865 sinking just after the end of the Civil War. Through group work, videos, and primary documents, they research and analyze why 1,800 men died....

First graders drop items into water, and discuss why some things float and others sink.

Will your next buoyancy lab rise to the occasion? Make a splash with action figure divers! Teams of young physicists explore the relationship between mass and buoyancy by adding weights or balloons to achieve a diver that neither sinks...

One of the key objectives of Europe's Copernicus Earth program is to monitor the temperatures of the oceans and seas on Earth. Young scholars learn the effects of different heat capacities through two experiments. These experiments...

Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.

Students answer questions about the Titanic, then read a news article about possible causes of the disaster. For this current events lesson, the teacher introduces the article with a discussion and vocabulary activity, then students read...

We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

They sunk our battleship! An engaging activity focuses on the Gulf of Tonkin Incident and the sinking of the USS Maddox. Young historians learn how it increased tensions leading to the Vietnam War and read through a first draft of the...

Students use their background knowledge of how scientists work to discuss and predict if a given object will sink or float. They record their predictions on a data sheet. Students test the objects and organize them into floating or...

Remember the Lusitania! As part of their study of the causes of World War I, class members examine newspaper articles and propaganda posters about the sinking of the Lusitania and then craft their own news story about the event.

You'll find everything but the kitchen sink here ... or just a carbon sink. In the activity, pairs or groups of middle school learners go outside and measure a tree's circumference and height to estimate its carbon storage potential and...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Were your chances of surviving the sinking of the Titanic better if you were a first-class passenger?  Capture learners' attention with actual historical data to find the answer. They use two-way tables to calculate conditional and...
