Learners construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

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...

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...

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...

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...

Build an air lift siphon using your mad physics skills! Learners first investigate the importance of circulating water in aquaponics systems. They then use density to their advantage as they engineer an air lift siphon

Potentially get all the way across the water. The fourth of five design challenges asks pupils to develop a plan for a paddle-powered boat that will store its energy. Given a limited number of supplies, the class members design, build,...

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 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 work with "ice" in order to gain a practical application of math concepts that evolve into an inquiry-based study. They determine if the dimensions of the ice make a difference in the way the ice floats in the water.

Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

After reading about the history and science of personal floatation devices, patents, and intellectual property, engineering teams design a life vest for a can of soup. To evaluate which groups considered the need for waterproofing, hold...

Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.

A neat handout immerses learners in the history of canoe making. After reading, small groups of mini engineers work to craft a canoe that will not be immersed! This is an ideal exercise in engineering design for your STEM curriculum or...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

Amaze your scholars with an activity that uses a Cartesian diver to demonstrate Pascal's Law, Archimedes' Principle, and the Ideal Gas Law. Groups then repeat the process and make their own diver move up and down in a bottle.

Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

In this Archimedes' principle instructional activity, high schoolers answer 13 questions about the concepts of Archimedes' principle such as water displacement, buoyancy and force. The answer questions from a lab they did in class to...

Students take a provided ocean Trivia Quiz in order to start a discussion of the ocean. They then perform an experiment on how the amount of salt in the ocean affects it and varies from ocean to ocean.

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.

In this density worksheet, students review how to calculate density and how to apply Archimedes' Principle, Boyle's Law, and Charles' Law. This worksheet has 10 matching, 13 short answer, and 6 fill in the blank questions.

Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.
