Curated OER
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...
Curated OER
Forces in Fluids
In this forces in fluids learning exercise, students identify the principles behind the forces acting upon objects in fluids that make them float, lift and spray.

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
Density Lab
In this biology worksheet, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in a graduate...
Curated OER
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. In this physics activity, 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
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
Density Challenge
Students calculate the densities of several liquids that appear similar. In this physical science instructional activity, students go beyond understanding the way liquids of different densities behave to researching how this...
Curated OER
Dunkin` for Density
In this density worksheet, 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...
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.
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
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
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
Density Destiny
Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.
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
Surface Tension and Bubbles
Students investigate surface tension and bubbles. In this scientific inquiry lesson plan, students explore how the surface tension of water is able to support tiny objects that actually weigh more than the water as they collect date by...
Curated OER
Science: Exploration Tubs
First graders develop skills of scientific inquiry. They determine which objects float and which sink.
Curated OER
The Weight of Water
Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.
Curated OER
Activity #16 Dancing Spagehetti
Students experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density materials. The...

Buoyant Force
Students illustrate Archimedes' Principle of Buoyant Force. In this graphing lesson, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Students will then create a graph showing...

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
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.
Curated OER
The Buoyancy Factor
Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...
