Action Figure Diver
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...

Density
Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.
Curated OER
Sink or Float
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.
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...

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...

A Cartesian Diver—Classic Chemistry Experiments
Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

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...

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
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
Immiscible Liquids and Density
Students will make a lava lamp. In this density instructional activity, 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
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Present Time and Past Time
Assess your English language learners and their ability to distinguish between present tense and past tense. Thirty multiple-choice questions are provided here, and learners must choose the correct verb conjugation.
Curated OER
Present Time and Past Time
Review past and present tense, and then give your class this worksheet to assess their current knowledge. There are 30 sentences to complete, and the sentences all deal with present and past tenses.

To Float or Not to Float - A Lesson on Density
Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.
Curated OER
Does Soap Float?
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.

Design a Submarine
Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...
Curated OER
What is Density?
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...

Defining Density
Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...
Curated OER
Design a Plankton
Young scholars explore animal and plant adaptation. In this ecosystems science lesson, students view websites to gain information about plankton and its interdependence within ecosystems. Young scholars identify ways in which...
Cornell University
Buoyancy
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...
Curated OER
Can You Make A Penny Float?
Students explore the concept of density by trying to make a penny and other materials float.
Curated OER
Vegetable Olympic Swimming: Will it Float?
Students inspect nutrition by conducting a science experiment in class. In this vegetable identification instructional activity, students examine a group of different veggies and predict whether they will sink or float in a tub of water....
Curated OER
Condiment Diver: The World's Simplest Cartesian Diver
Students examine buoyancy. In this density lesson students form a hypothesis, collect data and draw a conclusion using the data.
