Float and Sink
We're not talking about the kitchen sink. Learners explore what types of objects sink and float in water in an inquiry-based lesson. With experimentation, they find similarities between materials that float and those that sink.

Sink or Float
Second graders explore floating and sinking and make predictions about whether certain objects are likely to sink or float. They read the story Who Sank the Boat? by Pamela Allen. Pupils loacate rhyming words and discuss the events of...

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
Sink or Float
Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.

Liquids: Floating and Sinking
Third graders conduct an experiment. For this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

Water: Float and Sink
First graders work in small groups to observe the tendency to float or sink for a variety of objects in water. They sort the objects and discuss their observations. They use aluminum foil to construct a boat and test it for weight capacity.

Density: Sink and Float for Solids
Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

1st Grade - Act. 19: Will it Float?
First graders drop items into water, and discuss why some things float and others sink.
Curated OER
Sink/Float Discovery bottle
Investigate which items float and which ones sink using this resource. Learners participate in an activity in which they investigate this phenomena. Then they describe the experimental process, and learn how to display their results.

MEASURING THE DENSITY OF WATER
Students perform an experiment to measure the density of tap water vs. salt water.

Sink It
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.

Floating and Sinking
Students conduct experiments in which they investigate which materials float and which sink. They examine what qualities the materials that float have in common. They carry out a scientific investigation, predict, and test their...

Sink or Float?
Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Sink or Float?
Students investigate whether different objects sink or float in water using the Scientific Method. They listen to the book "Christopher Columbus" by Stephen Krensky, identify the steps of the Scientific Method, conduct the sink or 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...

Will It Sink Or Float?
Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Why Do Some Things Float?
Students recognize that density determines whether objects sink or float. In this sink or float instructional activity, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and...
