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

Physical Science- Sink or Float?
Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.

Sink or Float?
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.

Will It Sink or Float?
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...

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.

Sink or Float?
Students predict and test different items to see if they sink or float. In 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.

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.

A Weighty Issue
Want to get your students motivated in science class? Given only a piece of aluminum foil, assign groups the task of designing a "barge" that will support the weight of a bunch of pennies. The group who is able to put the most pennies...

Which Objects Will Sink or Float?
First graders work in cooperative groups and utilize a variety of materials to test objects ability to sink or float. In this sink or float lesson, 1st graders discover why some object sink and others float. Students will graph results...

Will it SINK or Float?
Students predict whether objects will sink or float in water. They classify objects as sinking or floating in water. Students identify and explain similarities between objects that sink and float.

Sink or Float
First graders explore items that sink or float. They cut and glue pictures of objects that they predict will sink or float. Students place thir pictures on a picture of a bucket of water. Students then color the objects that they had...

Sink or Float
Third graders sort objects into those they think will float and those that will sink and test their predictions. They experiment with clay molding it into shapes that float. They place pennies in them until they sink. They test other...

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!

Buoyancy-Why Things Float
In this buoyancy worksheet, students read about the principles behind objects floating including density, buoyancy and Archimedes' Principle. Students complete a buoyancy lab where they use a balloon and water and a film canister and...

Can You Make A Penny Float?
Students explore the concept of density by trying to make a penny and other materials float.

Buoyancy: What will float and what will sink
Students write and explain why an object sinks or floats. In this buoyancy lesson students demonstrate how items float or sink and graph the results.

Foil Boats
How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...

Density
Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

How Does the USS Alabama Float?
Young scholars investigate buoyancy. In this buoyancy instructional activity, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.

Designing and Floating Boats
Students participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom graph.

Solve a Problem: Build a Boat
Students build a boat that float and hold as many pennies as possible, then discuss the process of building the boat and relate the experience to experiences they encounter in life.
