Density Lab Activities
Young scholars 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
Concrete Canoes
Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.

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...

The Letter Ff: Alphabet Theme
Students complete several cross-curricular activities to learn the letter Ff. In this letter recognition lesson, students complete activities that include geography, music, physical education, science, seasonal, space science, and online...

What are Properties of Wood?
Students 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
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
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.

Day Two: Generating New Questions
Learners investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Learners analyze which items float and do not while...
Curated OER
Technology of the Deep: Experiments with Buoyant Forces
Young scholars 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
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.
Curated OER
Soap, Wood, and Water
Students 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.
Curated OER
Exploring the Properties of Matter in the Preschool
Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...
Reach Out!
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.

You Are What You Eat: Plastics and Marine Life
Young scholars study the different types of plastics and see which ones sink or remain buoyant. In this ocean environmental lesson plan students complete several handouts, and view a film on PBS.
Curated OER
Save the Bay
Students explore the concept of environmental stewardship. In this science lesson, students examine the environmental effects of oil spills as they replicate a contained oil spill and clean up.
Curated OER
Pumpkin Science
Young scholars investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Young scholars measure...
Curated OER
Science: Water States
First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.

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.
Curated OER
Wipe Out
Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson has streaming video, resource links to access, and a good hands-on activity that is clearly described in the...
It's About Time
Mass and Volume
Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

WS 1.7 Density /Archimedes Principle
Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

WS 1.7 Density
In this density learning exercise, students calculate the density of objects given their mass and volume. They are given a table with the density of a variety of substances and given the mass or volume and must find the unknown.

Motion in the Ocean
How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Simulating Microgravity with Buoyancy
How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...
