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...

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...

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...

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...

Fourth graders examine pumpkins and use the scientific method to explore its contents.  In this Pumpkin Science lesson, 4th graders measure pumpkins for circumference. Students dress as if they were in a lab and work in pairs to...

Students explore physical science by conducting an in-class experiment. In this density instructional activity, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Students experiment with different objects to test if they sink or float. They predict what the object will do before it is put into the water. They are allowed to play with the items after the experiment is over.

First graders conduct an experiment. In this density lesson, 1st graders work in groups to test 10 different objects to see which ones sink and float. Students discuss why certain objects float and others do not.

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

Students explore the concepts of float and sink by playing a game where they build things on mud, water, rock and jelly. In this Anthony's sink or float game lesson, students discover what materials remain strong in various conditions....

Students observe and classify objects that float or sink.

Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...

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...

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.

High schoolers consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how...

First graders drop items into water, and discuss why some things float and others sink.

Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...

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...

Learners construct clay boats and predict whether the boats will sink or float. Students will hypothesize what caused the boats to sink or float.

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.

Playing with balloons, water, oil, and bottles help put this instructional activity over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with...

Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...
