Science: Floating and Sinking Objects
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.

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...
Curated OER
Buoyancy
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.
Curated OER
Dragon Boats
Students create a model boat. In this art lesson plan, students identify what makes a boat float and use milk cartons to create their own boat.
Curated OER
I've Got That Sinking Feeling
Students 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 on buoyancy!
Curated OER
Ice Floats
Young scholars explore the changing density of water. In this physics instructional activity, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is...

Comparing the Density of an Object to the Density of Water
Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...
Curated OER
Will It Sink or Float?
Students perform experiments to see if items will sink or float. In this sink or float lesson, students work in groups to make predictions, and record the results. After the experiments are complete students make a book of the results.

Floaters and Sinkers
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...
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 is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.

Floating Fishes: How do Fishes Control Buoyancy?
Playing with balloons, water, oil, and bottles help put this lesson over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with buoyancy. Included...
Curated OER
What is Density?
Students explore physical science by conducting an in-class experiment. In this density activity, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink or float"...
Curated OER
To Float or Not to Float, That is the Question?
Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on
water or not, based on density, explain why some objects sink or float based on...
Curated OER
Ships 2: What Floats Your Boat?
Students design, build, and test the specifications (water displacement and load line) for a model boat. The instructional activity focuses especially on integrating design principles with inquiry-based experimental skills.

Density Workbook
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 cubes,...
Curated OER
Buoyancy and Viscosity
Some of these beautiful diagrams should help your students understand the connections between pressure and flight. Pressure and density are also discussed, and a number of links are included to give fantastic interactive examples of...
Curated OER
What Floats Your Boat?
Learners are introduced to the concept of buoyancy. The Video used in this lesson demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

Types of Marine Debris
Young scholars conduct an experiment. In this marine debris and environment protection lesson, students categorize trash into piles, predict whether these trash items will sink, float or be picked up and carried by the wind and then...
Curated OER
I'm Warm Now
Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. In this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...
