Curated OER
Student Exploration: Density Laboratory
In this density laboratory worksheet, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.
Curated OER
Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. In this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...
Curated OER
Specific Gravity-The Relative Density of Liquids
Students explore a hydrometer. In this gravity lesson students construct a hydrometer and create a liquid density column.
Curated OER
Density
Students explore the meaning of density. In this density lesson, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.
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
Muddy Waters: A historical view of land use patterns, water quality, and the conservation movement
Students research the impact that human activity had on Pennsylvania's water supply over time. In this water quality lesson plan, students research, discuss, and write about how Pennsylvania's water quality has been affected and what...
Curated OER
Density Discoveries
Learners participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.
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
Will It Sink Or Float?
Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.
Curated OER
What Floats Your Boat?
This open-ended boat building exercise is meant to be part of a three-activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load...
Curated OER
Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...
Curated OER
Buoyant Behavior
Combine science and literature with this lesson on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an egg...
Curated OER
Air Density and Temperature
Young scholars investigate the effect of temperature on the density of air by putting an uncovered bottle in a bucket of hot water. Then they place a balloon over the mouth of the bottle. They repeat the procedure using ice water and...
Curated OER
It's A Gas!
Fifth graders complete a learning exercise which has them place a list of gases in order from the least to the most dense. The density in grams is given for each. There's a good paragraph which provides background knowledge about the...
Curated OER
Liquids of Different Densities
Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.
Curated OER
Modeling Estuaries
Students create a model estuary. In this modeling estuaries lesson plan, students identify characteristics and mix water of varying densities. Students form a hypothesis, conduct an experiment, and analyze the results.
Curated OER
Big Enough?
Students explore the concept of density and buoyancy. In this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Students conduct several investigations to further understand...
Curated OER
Ice Floats
Students explore the changing density of water. In this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living things.
Curated OER
Fishy Physics
Learners explore how fish are able to move easily from one depth to another in water. In this fish lesson students create their own balloon fish.
Curated OER
Sink or Swim
Learners explore sinking and floating. In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Learners drop various soda cans into water and then discuss why some float and some sink.
Curated OER
Weighing a Dinosaur
Learners role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.
Teach Engineering
Aerogels in Action
Model an oil spill cleanup. An engaging engineering lesson has groups using aerogels to simulate an oil spill cleanup (vegetable oil in water). Along the way, they learn about nanotechnology and hydrophilia/hydrophobia.
Curated OER
Water Layering and Circulation
Young scholars examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
Curated OER
Activity: Float a Clay Boat
Written to introduce pupils to buoyancy, this activity has collaborative groups work to design a floatable clay boat. They first observe that a stick of clay sinks in water and then are given their own stick to reshape into a floating...
