Curated OER
The Weight of Water
Students 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
Buoyant Force
Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...
Curated OER
Icebergs Ahead!
Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.
Curated OER
Density and Buoyancy Lesson Plan
Young scholars 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.
Curated OER
Density Lab Activities
Pupils 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.
Curated OER
Making Predictions
First graders write with his or her pencil on a worksheet created by the teacher his or her prediction of whether each part of a pumpkin will sink or float. They drop each of five objects in the water one at a time allowing enough time...
Curated OER
Ice is N"ICE"!!
Students observe and describe, both orally and in writing. the different forms of water on the surface of the Earth and measure the approximate size of an iceberg. They also estimate and measure the amount of ice that floats above the...
Curated OER
Science: Different Levels of Density
Students observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into each...
Curated OER
Using Inspiration To Support Logical Reasoning
Young scholars share descriptions of science experiments they have conducted. They create a thin film on the surface of water in order to float light objects and observe that a paper clip does, indeed, float on the surface of the...
Curated OER
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...
Curated OER
Lusitania: Murder on the Atlantic
Pupils explore the pride of the Cunard line and a jewel in the British crown; a floating four star hotel. But during World War I, the RMS Lusitania carried more than well-to-do travelers luxuriating in her sumptuous appointments.
Curated OER
The Earth's Magnetic Field
Pupils explain how the earth's magnetic field works and looks. They create
their own free-floating compass using the everyday materials. After constructing their compass, they test it and determine north.
Curated OER
Properties of Matter: "Sink or Swim"
Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...
Curated OER
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...
Curated OER
Cold Hard Facts? What Inquiring Minds Will Know -- Inquiry-Based Ice Investigations
Students are introduced to the concepts of perimter, diameter, circumference and measurements. In groups, they complete two worksheets in which they determine if the ice dimensions make a difference in the way it floats. They discuss...
Curated OER
Density and Buoyancy Experimental Design
Students 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."
Curated OER
Air and Water Pressure
Students examine buoyancy and fluid pressure. They conduct a series of fun experiments to discover the effects of pressure and explore how pressure differences can be used to float, lift, transport, or hold a material in place.
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
I Need Air
Learners examine and research the organs of the respiratory system. They participate in a vocabulary card matching game, create a graphic organizer, and participate in an experiment titled, Floating on Air.
Curated OER
Instructors Lesson Plan for Casting Shadows
Students create quilts with shadow effects, that create three dimensional effects that make the pieces appear to float right off the surface. They use several techniques to create the shadows such as; color and value, piecing, applique...
Curated OER
Flotation
Pupils examine how one of the ways the mining companies extract coal is through the flotation method where air bubbles float coal particles to the top of a solution. The coal is scooped off and separated. They participate in the "Popcorn...
Curated OER
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...
Curated OER
Ship Building in Action
Students define the purpose of several different types of boats. They develop a list of materials one would ideally use in the construction of a particular type of boat. Students work cooperatively in a group to decide what type of boat...
Curated OER
Deep Ocean Currents
Young scholars observe the interactions of different temperatures of water using colored ice and a thermometer and then compare the results with global ocean current solar heating. They identify where floating ice would be found in the...
