Lesson Planet: Curated OER

#### Ice Floats

Young scholars explore the changing density of water. In 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...

Lesson Planet: Curated OER

#### Freshwater/Saltwater "Eggs-Periment"

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...

Lesson Planet: Curated OER

#### Creating the Ideal Cargo Boat

Students build boats out of clay to test the buoyancy of the boat in water. Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.

Lesson Planet: Curated OER

#### Staying Up

Students will explain the Archimedes's Principle. In this lesson on plankton, students will describe three factors that can affect the buoyancy of plankton. This lesson contains extensive background information, extensions, and multiple...

Lesson Planet: Curated OER

#### What's the Best Design to Float Your Boat?

Students design a boat with buoyancy. In this designing a boat with buoyancy lesson, students design a boat out of foil, tape, clay, glue, toothpicks, straws, etc. Students design a boat that displaces the most water. Students watch a...

Lesson Planet: Curated OER

#### Ships to a New World

Students experiment with buoyancy as a force. In this buoyancy lesson plan, students access an assigned website to examine the sailing vessels that came to the New World. They work as teams to build boats out of aluminum foil to see...

Lesson Planet: Curated OER

#### How Fish Maintain Neutral Buoyancy

In this buoyancy instructional activity, students read about neutral buoyancy and that the downward force of gravity is equal and opposite to the upward force of water. They answer four critical thinking questions about buoyancy.

Lesson Planet: Curated OER

#### Sink or Float: Exploring the Laws of Buoyancy

Students explore the relationship between density and buoyancy. After watching a video explaining buoyancy, students discuss displacement and floating. Students have a raft building competition. Afterward, they conduct experiments to...

Lesson Planet: Curated OER

#### Who Sank the Boat?

Fifth graders experiment with student-made aluminum boats to test for buoyancy. They design a boat and determine how many marbles it takes to sink it while recording their data in a spreadsheet. They design a graph using the data and...

Lesson Planet: Curated OER

#### Floating and Falling Flows

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Lesson Planet: Curated OER

#### Salinity

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.

Lesson Planet: Curated OER

#### I've Got That Sinking Feeling

Middle schoolers design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson plan on buoyancy!

Lesson Planet: Curated OER

#### What Floats Your Boat?

Young scholars are introduced to the concept of buoyancy. The Video used in this instructional activity demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and...

Lesson Planet: Curated OER

#### Cold Hard Facts...What Inquiring Minds Will Know

Young scholars 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.

Lesson Planet: Curated OER

#### What Floats Your Boat?

Students explore the principles of buoyancy and Archimedes' Principle and design their own flotation device. They compare the dimensions of a model to the real object to determine scale and analyze the models to suggest improvements.

Lesson Planet: Curated OER

#### Barge Building: What Floats Your Boat?

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Lesson Planet: Curated OER

#### Buoyant Boats

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.

Lesson Planet: Curated OER

#### Does Soap Float?

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

Lesson Planet: Curated OER

#### Floating Fishes: Boat Sinking Lab

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,...

Lesson Planet: Curated OER

#### Activity: Float a Clay Boat

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...

Lesson Planet: Curated OER

#### Day Two: Generating New Questions

Students investigate buoyancy by participating in a lab experiment. In this density activity, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float and do not...

Lesson Planet: Curated OER

#### Density and Buoyancy Lesson Plan

Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.
