It Floats

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Build a floating vessel capable of carrying cargo. Groups create a vessel that floats and can carry at least 10 pennies to model a mass transit system. After learning about buoyancy, density, and energy, they redesign their vessels in...

Learners conduct a science experiment to determine whether a variety of objects will sink or float. They discuss the concept of density, and then make predictions about whether the objects will sink or float. They then conduct the...

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.

Mixing substances together causes their properties to change. This resource illustrates that concept for fifth graders by having them consider four questions that have to do with buoyancy and boiling point. Learners begin to understand...

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.

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.

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.

Students predict and test different items to see if they sink or float. For this sink and float lesson plan, students predict whether an item is buoyant or not, and learn that size and weight do not matter when it comes to buoyancy.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
