Curated OER
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...
Curated OER
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.
Curated OER
Density - To Float or Not to Float? That is the Question!
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.
Curated OER
Density Laboratory Gizmo
In this mass worksheet, students fill in a chart with different items and their volume, whether they float or sink, and their density. Students complete this for 10 items and answer 6 multiple choice mass questions.
Curated OER
Technology of the Deep: Experiments with Buoyant Forces
Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.
Curated OER
The Floating Golf Ball
Students explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring, they...

Activity # 13 Float or Sink?
Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

Scuba Training
How does a scuba diver control whether they sink or float? Scholars observe the relationship between absolute pressure and depth below the surface in an undersea simulation. They control the diver size and depth to center of mass to...
Curated OER
Sink or Float?
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...
Curated OER
The Weight of Water
Pupils examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
Curated OER
Move that Tower
Young scholars investigate ways to find the density of irregular shaped objects. For this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.
Curated OER
Leaky Seal
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...
Curated OER
Water Olympics
A fascinating and engaging instructional activity on the properties of water awaits you. In it, learners engage in four activities that are designed to teach about the properties of water. This exciting plan has worksheets embedded in it...
Curated OER
Density Studies of the Earth
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...
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.
Curated OER
States of Matter
Properties in measurement, pressure and viscosity of solids, liquids, and gases are the main topics covered in this slideshow. The explanations of Pascal's, Bernoulli's, and the Venturi effects are very clear. Easy to understand diagrams...
Discovery Education
Future Fleet
Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...
Curated OER
Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...
Curated OER
Immiscible Liquids and Density
Students will make a lava lamp. In this density lesson plan, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.
Curated OER
Plate Tectonics Study Guide
In this plate tectonics worksheet, students answer questions about plate tectonics including topics such as the lithosphere, the asthenosphere, rising and sinking convection currents, continental drift and the types of boundaries.
Curated OER
Water and Ice
Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.
Curated OER
Exploring Buoyancy
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...
