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.

Written to introduce pupils to buoyancy, this activity has collaborative groups work to design a floatable clay boat. They first observe that a stick of clay sinks in water and then are given their own stick to reshape into a floating...

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.

Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...

Students work in small groups and design a ship out of balsa wood. They hypothesize what happens when the ship is placed in water then make predictions as to which ship stays afloat the longest with the greatest amount of weight added.

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

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.

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Learners examine the relationship between density and buoyancy.  In this physics lesson students use Archimedes' Principle to complete calculations on buoyancy and a lab activity.

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.

Students study how buoyancy, pressure, and light can effect the work of underwater scientists.  In this marine science lesson students complete a lab that allows them to better understand how pressure varies with altitude and...

Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...

Students examine buoyancy.  In this density lesson students form a hypothesis, collect data and draw a conclusion using the data. 

Students research the implementation of a research vessel used for ocean exploration.  In buoyancy instructional activity students will construct a device that shows neutral buoyancy.

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...

Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.

Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.
