Buoyancy
This is a brief survey of the states and properties of matter directed toward upper elementary physical scientists. Solids and liquids are compared. Density and buoyancy are related. Use this presentation just prior to demonstrating...
Curated OER
Immiscible Liquids and Density
Students will make a lava lamp. In this density lesson, 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
Buoyant Boats
Students design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.
Curated OER
Density and Mass
Students experiment to find which liquids are more dense. In this density and mass instructional activity, students predict and then test objects to observe and measure their density. students observe which items sink and float....
Curated OER
Design a Plankton
Students explore animal and plant adaptation. In this ecosystems science lesson, students view websites to gain information about plankton and its interdependence within ecosystems. Students identify ways in which plankton...

Paper Clip Sailing
Students explore water, molecules, and surface tension. In this floatation lesson, students discover why some objects are able to float on water as they follow the procedures included in this activity.
Curated OER
Move that Tower
Students investigate ways to find the density of irregular shaped objects. In this physics lesson plan, students calculate density using its mass and volume. They explain why some objects float or sink in 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
Density Phenomena-Using the Concept of Density
Learners investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...
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.
Anglophone School District
Fluids: Force in Fluids
Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Manifest Density
There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...
Curated OER
Mystery Canisters
For 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
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
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
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
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
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
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
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.
