Junior high schoolers explore possible theories for the cause of the Hunley submarine sinking. Through hands on activities, they investigate how to create a waterproof seal. Afterwards, they discuss how seals work and various...

An engating lesson plan relates mass and volume to better understand density. Young scientists explore and experiment with floating and sinking as well as density cubes. Then, they solve how to make a sinking item 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...

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

Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.

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...

Some of these beautiful diagrams should help your students understand the connections between pressure and flight. Pressure and density are also discussed, and a number of links are included to give fantastic interactive examples of...

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...

Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...

Students use the Scientific Method steps to complete an experiment on various brands of soap to determine their floating capabilities. In this scientific method lesson, students write a hypothesis about the ability of various soap bars...

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students explore the density of soap. In this science lesson, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.

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.

In this buoyancy worksheet, students read about why objects float or sink. Students apply the Archimedes' Principle in a buoyancy lab. Students complete 1 graphic organizer.

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

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!

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

Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. In this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...

Pupils 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.

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...

Learners design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills.

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....

Third graders conduct an experiment. In 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.

Middle schoolers are introduced to the concept of buoyancy. The Video used in this lesson demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.
