This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...

Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.

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 investigate buoyancy by participating in a lab experiment. In this density instructional activity, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float...

Students observe earth science by examining results from an experiment. For this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

In this buoyancy worksheet, students review Archimedes principle and the difference between positive, negative, and neutral buoyancy. This worksheet has 1 fill in the blank and 7 short answer questions.

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.

Collaborative groups work together with a variety of materials to design an eight-inch canoe that floats for at least three minutes. There is no direct instruction involved in this plan, just a list of materials and a procedure for...

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, students 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 simulate...

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...

Learners look at clippings of boats. They are able to define the following terms displacement, and density. Students construct a clay boat. After they complete their clay boat learners answer questions about their clay boats.

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...

Students design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Students 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 living things.

Learners 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.

Cut milk cartons in half to make boats and let investigators attempt to sink them. They add dividing walls and observe what happens if marbles are put into only one of the newly formed compartments. Vocabulary is provided: buoyant force,...

High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

Have you ever examined a pumpkin and estimated the number of lines it has? For this math lesson, students count the actual number of lines, record and graph the results. They investigate the circumference, weight and buoyancy of the...

Fifth graders investigate buoyancy by conducting a science experiment.  In this water properties lesson, 5th graders predict which of their different paper boat designs will float for the longest period.  Students conduct the...

Students explore the concept of buoyancy through experimentation. Given materials of various weights and composition, they drop them in club soda and determine which substances sink or float. Students discuss their results in terms of...

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...
