Students participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom graph.

In this buoyancy worksheet, students read about why objects float or sink. Students apply the Archimedes' Principle in a buoyancy lab. Students complete 1 graphic organizer.

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.

Save the soup! Scholars devise a flotation device using straws, balloons, foam, corks, and other objects. A can of soup must stay afloat for at least a minute with this device—your dinner might depend on it!

In this buoyancy worksheet, students read about the principles behind objects floating including density, buoyancy and Archimedes' Principle. Students complete a buoyancy lab where they use a balloon and water and a film canister and...

In this density learning exercise, students read about density, volume and mass. They then use what they learned to answer the 8 questions on the page. The answers are on the last page.

Young scholars explore the changing density of water. For this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to...

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's as good a material as any to build a boat, right? An introductory lesson plan sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure...

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...

It's all about density! Here's a dense workbook for young scientists; they solve (and show work for) 29 density word problems, including a problem where they solve for the density of Godzilla. They complete labs analyzing metal...

Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...

In this deducing density worksheet, students follow the procedures to set up an experiment about objects floating in water and liquids of different densities, answer questions, collect data and complete charts.

Students investigate buoyancy. In this buoyancy instructional activity, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

Students observe teacher demonstrations that illustrate density. In this density instructional activity, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but...

Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens.  In this Hindenburg lesson, 10th graders watch a demonstration called the invisible...

Students explore water, molecules, and surface tension. For this floatation lesson, students discover why some objects are able to float on water as they follow the procedures included in this activity.

In this forces in fluids worksheet, students identify the principles behind the forces acting upon objects in fluids that make them float, lift and spray.

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...

Pupils explore the characteristics of water. In this water exploration lesson, students participate in various learning centers to inquire how water drains and how to increase the flow of water. Pupils use estimation and measurement in...

Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.

How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...
