Design a Flotation Device
Save the soup! Scholars devise a flotation device using straws, balloons, foam, corks, and other objects. A can of soup must stay afloat for at least a minute with this device—your dinner might depend on it!

Note Taking And Skills And Lab Reports
Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...

Temperature Affects Density
Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

Buoyant Boats
Students design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Design a Plankton
Students explore animal and plant adaptation. In this ecosystems science lesson, students view websites to gain information about plankton and its interdependence within ecosystems. Students identify ways in which plankton...

Move that Tower
Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Density Phenomena-Using the Concept of Density
Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...

It Matters
Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Forces in Fluids
In this forces in fluids worksheet, learners identify the principles behind the forces acting upon objects in fluids that make them float, lift and spray.
Curated OER
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. For this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.
Curated OER
Density Lab Activities
Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

"Mr. Betts and Mr. Potts"
First graders listen to the book "Mr. Betts and Mr. Potts" and examine the career of being a veterinarian. They categorize animals based on whether they could be house pets or not, develop a class pet graph, and list the various...

Rock and Boat
Present the class with a question on whether the water level of a pond will rise they take a large rock out of a boat and drop it into the pond. Groups come down on all sides of the question and try to justify their answers. The activity...
Curated OER
Water and Ice
Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Mystery Canisters
In this density worksheet, students modify three film canisters in order to make one float in a tank of water, another suspend in the middle of the tank, and the third should sink to the bottom. They collect data on their canisters and...

Dunkin` for Density
In this density activity, 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...

Density and Buoyancy Experimental Design
Young scholars must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

What are Properties of Wood?
Young scholars use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...

Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Who Sunk the Titanic
Students discuss possible reasons for the Titanic sinking. They are split into small groups to research a historical figure involved in the sinking of the Titanic. They formulate a way to prove their characters guilt or innocence....
Curated OER
Soap, Wood, and Water
Young scholars measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

Paper Clip Sailing
Students explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.

Chemistry: The Case of the Sunken Ice Cube
Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...
