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...

Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Students create a model boat. In this art lesson, students identify what makes a boat float and use milk cartons to create their own boat.

Students conduct an experiment.  In this marine debris and environment protection instructional activity, students categorize trash into piles, predict whether these trash items will sink, float or be picked up and carried by the...

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...

Combine science and literature with this activity on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

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...

Students examine how weight and balance can effect if an item sinks or floats. They listen to the book "Who Sank the Boat?" by Pamela Allen, and discuss how the smallest animal sank the boat. Students then conduct an experiment in...

Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...

In this density worksheet, students complete a science lab experiment to determine the density that an object will float or sink in water. Students fill in a chart with their data, answer 4 short answer questions and write 1 conclusion...

Will your next buoyancy lab rise to the occasion? Make a splash with action figure divers! Teams of young physicists explore the relationship between mass and buoyancy by adding weights or balloons to achieve a diver that neither sinks...

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...

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...

In this density learning exercise, students read about density, volume and mass. They then use what they learned to answer the 8 questions on the page. The answers are on the last page.

Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...

First graders discuss with the teacher if everything will float in water. They observe a marble and determine whether it will float making predictions as a class. After observing the results, they discover that liquids exert an upward...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...

In this density worksheet, students calculate the density of objects given their mass and volume. They are given a table with the density of a variety of substances and given the mass or volume and must find the unknown.

Let's go sailing! An instructive unit includes six lessons with multiple activities to teach scholars about density, center of gravity, buoyancy, and the Archimedes Principle. They can complete the final project of building a boat...

In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...
